Migrate from v5 to v6

The Auth category has moved to a functional approach and named parameters in Amplify v6, so you will now import the functional API’s directly from the aws-amplify/auth path as shown in the examples below and will need to pay close attention to the changes made to inputs and outputs. You can use the switcher on the API examples to see the differences between v5 and v6 implementations. (v6 is shown by default)

Auth.signUp

The overall input to Auth.signUp is largely unchanged, but how the object is structured is slightly different: attributes becomes userAttributes , and userAttributes and validationData are now under an options object. autoSignIn can also now be a simple boolean value.

A major difference is that a CognitoUser is no longer returned from signUp. All Auth API’s now use the current signed in user information to perform operations, so sending and receiving CognitoUser through every API is no longer required.

Also notice that userConfirmed is no longer returned, and instead we return nextStep. This follows a standardized format shared between the signUp, signIn, resetPassword, and updateUserAttributes flows, where additional authentication steps will be returned with any additional information included in the same object (in this case, codeDeliveryDetails)

autoSignIn is no longer triggered automatically in v6 and will need to be called manually through a separate API when the nextStep.signUpStep is COMPLETE_AUTO_SIGN_IN
Input

V5

// Standard
params: SignUpParams {
username: string;
password: string;
attributes?: object;
validationData?: {
[key: string]: string;
}
clientMetadata?: { [key: string]: string; };
autoSignIn?: {
enabled: boolean;
clientMetaData?: { [key: string]: string; };
validationData?: {
[key: string]: string;
}
};
}
// Legacy
username: string
password: string
email: string
phone_number: string

V6

userAttributes?: { [key: string]?: string; }
validationData?: { [key: string]: string; };
clientMetadata?: { [key: string]: string; };
autoSignIn?: boolean | {
authFlowType?:
| 'USER_SRP_AUTH'
| 'CUSTOM_WITH_SRP'
| 'CUSTOM_WITHOUT_SRP'
| 'USER_PASSWORD_AUTH';
clientMetadata?: { [key: string]: string; };
};
};
}
Output

V5

ISignUpResult {
user: CognitoUser;
userConfirmed: boolean;
userSub: string;
codeDeliveryDetails: {
AttributeName: string;
DeliveryMedium: string;
Destination: string;
};
}

V6

SignUpOutput {
isSignUpComplete: boolean;
userId?: string;
nextStep: {
signUpStep:
| 'DONE'
| 'CONFIRM_SIGN_UP'
| 'COMPLETE_AUTO_SIGN_IN',
codeDeliveryDetails: { // Not included when signUpStep is 'DONE'
destination?: string;
deliveryMedium?:
| 'EMAIL'
| 'SMS'
| 'PHONE'
| 'UNKNOWN';
attributeName?: UserAttributeKey;
}
};
}
import { signUp } from 'aws-amplify/auth';
const handleSignUp = async ({
username,
password,
email,
phone_number,
validationData
}) => {
const {
isSignUpComplete,
userId,
nextStep
} = await signUp({
username,
password,
options: {
userAttributes: {
email,
phone_number
},
validationData
}
});
}
import { Auth } from 'aws-amplify';
const handleSignUp = async ({
username,
password,
email,
phone_number,
validationData
}) => {
const { user } = await Auth.signUp({
username,
password,
attributes: {
email,
phone_number
},
validationData
});
}

Auto Sign-in

autoSignIn is no longer triggered automatically in v6
import {
autoSignIn,
confirmSignUp,
signUp
} from 'aws-amplify/auth';
// 1. Sign Up with autoSignIn enabled
const handleSignUp = async ({
username,
password,
email,
phone_number,
validationData
}) => {
const {
isSignUpComplete,
userId,
nextStep
} = await signUp({
username,
password,
options: {
userAttributes: {
email,
phone_number
},
validationData,
autoSignIn: true
},
});
}
// 2. Confirm Sign Up
const handleConfirmSignUp = async ({
username,
confirmationCode
}) => {
const {
isSignUpComplete,
userId,
nextStep
} = await confirmSignUp({
username,
confirmationCode
});
// 3. Trigger autoSignIn event - will not be triggered automatically
const { isSignedIn } = await autoSignIn();
}
import { Auth, Hub } from 'aws-amplify';
// 1. Add listener for autoSignIn event
Hub.listen('auth', ({ payload }) => {
const { event } = payload;
if (event === 'autoSignIn') {
const confirmedUser = payload.data;
} else if (event === 'autoSignIn_failure') {
// redirect to sign in page
}
});
// 2. Sign Up with autoSignIn enabled
const handleSignUp = async ({
username,
password,
email,
phone_number,
validationData
}) => {
const { user } = await Auth.signUp({
username,
password,
attributes: {
email,
phone_number
},
validationData,
autoSignIn: {
enabled: true
}
});
}
// 3. Confirm Sign Up - this will trigger autoSignIn
const handleConfirmSignUp = async ({
username,
confirmationCode
}) {
await Auth.confirmSignUp(username, confirmationCode);
}

Legacy

In the past, we've supported the ability to pass in username, password, email, phone_number as positional parameters instead of as named input parameters for Auth.signUp for backwards compatibility with older versions of Amplify JavaScript. The following guide shows you how to migrate from that legacy call pattern for Auth.signUp:

import { signUp } from 'aws-amplify/auth';
const handleSignUp = async ({
username,
password,
email,
phone_number,
validationData
}) => {
const {
isSignUpComplete,
userId,
nextStep
} = await signUp({
username,
password,
options: {
userAttributes: {
email,
phone_number
}
}
});
}
import { Auth } from 'aws-amplify';
const handleSignUp = async ({
username,
password,
email,
phone_number,
validationData
}) => {
const { user } = await Auth.signUp(
username,
password,
email,
phone_number
);
}

Auth.confirmSignUp

In v6, confirmSignUp now takes named parameters instead of positional parameters. You will send in an object with the properties username, confirmationCode, and options. This API also returns an object containing an isSignUpComplete flag, the userId, and nextStep for autoSignIn use cases in v6.

autoSignIn is no longer triggered automatically in v6 and will need to be called manually through a separate API when the nextStep.signUpStep is COMPLETE_AUTO_SIGN_IN
forceAliasCreation defaulted to true in v5 but is left undefined by default in v6
Input

V5

username: string
code: string
options?: ConfirmSignUpOptions {
forceAliasCreation?: boolean;
clientMetadata?: { [key: string]: string; };
}

V6

input: ConfirmSignUpInput = {
username: string;
confirmationCode: string;
options?: {
clientMetadata?: { [key: string]: string; };
forceAliasCreation?: boolean;
};
}
Output

V5

'SUCCESS'

V6

type ConfirmSignUpOutput = {
isSignUpComplete: boolean;
userId?: string | undefined;
nextStep: {
signUpStep:
| 'DONE'
| 'CONFIRM_SIGN_UP'
| 'COMPLETE_AUTO_SIGN_IN',
codeDeliveryDetails: { // Not included when signUpStep is 'DONE'
destination?: string;
deliveryMedium?:
| 'EMAIL'
| 'SMS'
| 'PHONE'
| 'UNKNOWN';
attributeName?: UserAttributeKey;
}
};
}
import { confirmSignUp } from 'aws-amplify/auth';
const handleConfirmSignUp = async ({
username,
confirmationCode
}) {
const {
isSignUpComplete,
userId,
nextStep
} = await confirmSignUp({
username,
confirmationCode
});
}
import { Auth } from 'aws-amplify';
const handleConfirmSignUp = async ({
username,
confirmationCode
}) {
await Auth.confirmSignUp(
username,
confirmationCode
);
}

Force Alias Creation

forceAliasCreation defaulted to true in v5 but is left undefined by default in v6
import { confirmSignUp } from 'aws-amplify/auth';
const handleConfirmSignUp = async ({
username,
confirmationCode
}) {
const {
isSignUpComplete,
userId,
nextStep
} = await confirmSignUp({
username,
confirmationCode,
options: {
// default falsy (undefined)
forceAliasCreation: true
}
});
}
import { Auth } from 'aws-amplify';
const handleConfirmSignUp = async ({
username,
confirmationCode
}) {
await Auth.confirmSignUp(
username,
confirmationCode,
options: {
// default true
forceAliasCreation: false
}
);
}

Auth.resendSignUp

In v6, resendSignUp now takes named parameters instead of positional parameters. You will send in an object with the properties username and options, with clientMetadata nested under options for consistency across API's. The output has also been updated to match other API's, returning an object with destination, deliveryMedium, and attributeName properties instead of the PascalCase CodeDeliveryDetails.

Input

V5

username: string
clientMetadata?: ClientMetaData {
[key: string]: string;
}

V6

input: ResendSignUpCodeInput {
username: string;
options?: {
clientMetadata?: { [key: string]: string; };
};
}
Output

V5

{
CodeDeliveryDetails: {
AttributeName: string,
DeliveryMedium: string,
Destination: string
}
}

V6

ResendSignUpCodeOutput {
destination?: string;
deliveryMedium?:
| 'EMAIL'
| 'SMS'
| 'PHONE'
| 'UNKNOWN';
attributeName?: AuthVerifiableAttributeKey;
}
import { resendSignUpCode } from 'aws-amplify/auth';
const handleResendCode = async ({ username }) => {
const {
destination,
deliveryMedium,
attributeName
} = await resendSignUpCode({ username });
}
import { Auth } from 'aws-amplify';
const handleResendCode = async ({ username }) => {
const { CodeDeliveryDetails } = await Auth.resendSignUp(username);
}

Auth.signIn

The input to Auth.signIn is largely unchanged in the v6 signIn API, but how the object is structured is slightly different: clientMetadata is now under an options object that also includes an authFlowType option if needed.

A major difference is that a CognitoUser is no longer returned from signIn. All Auth API’s now use the current signed in user information to perform operations, so sending and receiving CognitoUser through every API is no longer required.

Also notice that challengeName and challengeParam (returned in v5 as additional properties on the CognitoUser) are replaced in the output object by the nextStepproperty. nextStep includes signInStep and possibly additional props depending on the step. See the Confirmation Required example for a detailed example of the new signIn flow.

The signIn API no longer accepts validationData in v6: in v5 validationData was not used because the underlying Cognito API does not accept validationData
Input

V5

// Standard
usernameOrSignInOpts: SignInOpts {
username: string;
password: string;

Legacy

In the past, we've supported the ability to pass in username, password as positional parameters instead of as named input parameters for Auth.signIn for backwards compatibility with older versions of Amplify JavaScript. The following guide shows you how to migrate from that legacy call pattern for Auth.signIn:

import { signIn } from 'aws-amplify/auth';
const username = 'username';
const password = 'password';
const handleSignIn = async ({
username,
password

const {
isSignedIn,
nextStep
} = await signIn({ username, password });
}
import { Auth } from 'aws-amplify';
const handleSignIn = async ({
username,
password
}) => {
const user = await Auth.resendSignUp(
username,
password
);
}

Auth.federatedSignIn

Auth.federatedSignIn has become signInWithRedirect in v6, but is otherwise similar. The provider property accepts specific strings instead of an enum and also includes an option to send in a custom provider if you would like to use a provider not in the default list. For this use case you would pass an object containing the prop custom to provider instead of one of the predefined strings.

The usage of federatedSignIn with Identity Pools is deprecated. If you are using an Identity Pool for authentication, please follow this guide.
Input

V5

// Standard
options?: FederatedSignInOptions {
provider: { // enum
Cognito = 'COGNITO',
Google = 'Google',
Facebook = 'Facebook',
Amazon = 'LoginWithAmazon',
Apple = 'SignInWithApple',
};
customState?: string;
}
// Custom Provider
options?: FederatedSignInOptionsCustom {
customProvider: string;
customState?: string;
}
// Legacy
provider:
| 'google'
| 'facebook'
| 'amazon'
| 'developer'
| string
response: FederatedResponse {
token: string;
identity_id?: string;
expires_at: number;
}
user: FederatedUser {
name: string;
email?: string;
picture?: string;
}

V6

input?: SignInWithRedirectInput {
provider?:
| 'Amazon'
| 'Apple'
| 'Facebook'
| 'Google'
| { custom: string; };
customState?: string;
options?: {
preferPrivateSession?: boolean;
};
}
Output

V5

// Only returns when FederatedResponse from Identity Pools is provided
ICredentials {
accessKeyId: string;
sessionToken: string;
secretAccessKey: string;
identityId: string;
authenticated: boolean;
expiration?: Date;
}

V6

No output in v6

}

Custom Provider

import { signInWithRedirect } from 'aws-amplify/auth';
const handleSocialSignIn = () => {
signInWithRedirect({
provider: {
custom: 'SocialProvider'
}
});
}
import { Auth } from 'aws-amplify';
const handleSocialSignIn = () => {
Auth.federatedSignIn({
customProvider: 'SocialProvider'
});
}

import { signInWithRedirect } from 'aws-amplify/auth';
const handleSocialSignIn = () => {
signInWithRedirect();
}
import { Auth } from 'aws-amplify';
const handleSocialSignIn = () => {
Auth.federatedSignIn();
}

Identity Pools - DEPRECATED

signInWithRedirect does not allow you to pass a pre-authorized user and tokens for Amplify to consume. Follow this guide as an example of how to accomplish this in v6.

Auth.confirmSignIn

In v6, confirmSignIn is now used not only for MFA confirmation, but also in place of Auth.completeNewPassword and Auth.sendCustomChallengeAnswer. The input no longer includes mfaType and code separately, but rather contains challengeAnswer, which will allow you to pass the required information (including MFA type or a new password) as a value. See the Auth.signIn: Confirmation Required example for a detailed example of the new signIn flow.

Another major difference is that CognitoUser is no longer required as an input parameter or returned from confirmSignIn. All Auth API’s now use the current signed in user information to perform operations, so sending and receiving CognitoUser through every API is no longer required.

Also notice that challengeName and challengeParam (returned in v5 as additional properties on the CognitoUser) are replaced in the output object by the nextStep property. nextStep includes signInStep and possibly additional props depending on the step.

Input

V5

user: CognitoUser
code: string
mfaType?: 'SMS_MFA' | 'SOFTWARE_TOKEN_MFA' | null
clientMetadata?: ClientMetaData {

const handleConfirmSignIn = async ({
user,
code,
mfaType
}) => {
const user = await Auth.confirmSignIn(
user,
code,
mfaType
);
}

Auth.setupTOTP

There is now no input for setupTOTP in v6. All Auth API’s in v6 use the current signed in user information to perform operations, so sending and receiving CognitoUser through every API is no longer required.

The output is no longer just a string representing the secret code, but an object with a property called sharedSecret and the method getSetupUri that builds and returns the setup uri needed for TOTP authentication based on that secret.

Input

V5

user: CognitoUser

V6

No input in v6

Output

V5

string // secretCode

V6

SetUpTOTPOutput {
sharedSecret: string;
getSetupUri: (appName: string, accountName?: string | undefined) => URL;
}
import { setUpTOTP } from 'aws-amplify/auth';
const handleSetupTOTP = async () => {
const output = await setUpTOTP();
const secretCode = output.sharedSecret;
const setupUri = output.getSetupUri('sample-app');
}
import { Auth } from 'aws-amplify';
const handleSetupTOTP = async ({ user }) => {
const secretCode = await Auth.setupTOTP(user);
const setupUri = `otpauth://totp/AWSCognito:${user}?secret=${secretCode}&issuer=sample-app`;
}

Auth.verifyTotpToken

In v6, Auth.verifyTotpToken has become verifyTOTPSetup, and the input has changed: you no longer need to send in a CognitoUser and the challengeAnswer parameter has become the code property in the input object. The method also no longer returns a CognitoSession: see Auth.currentSession for details on how you would retrieve the current session details returned in v5.

Input

V5

user: CognitoUser
challengeAnswer: string

V6

input: VerifyTOTPSetupInput {
code: string;
options?: {
friendlyDeviceName?: string;
}
}
Output

V5

const handleVerifyTOTP = async ({ user, code }) => {
const userSession = await Auth.verifyTotpToken(user, code);
}

Auth.completeNewPassword (DEPRECATED)

This API has been deprecated: existing use cases can be migrated to the confirmSignIn API, which returns an object with nextStep instead of a CognitoUser with challengeName and challengeParam. For a comprehensive example on the full v6 signIn flow and how to respond to each nextStep value, see the Auth.signIn Confirmation Required example.

Auth.getPreferredMFA

In v6, Auth.getPreferredMFA has become the fetchMFAPreference API. This API no longer accepts a CognitoUser: all Auth API’s now use the current signed in user information to perform operations, so sending and receiving CognitoUser through every API is no longer required. There is also no longer a bypassCache option in v6, as fetchMFAPreference will always make a call to the server.

The return value in v6 is no longer just a string, but is now an object containing an enabled array and a preferred string.

Cognito can have multiple enabled MFA options: as of now, it only supports TOTP and SMS. An MFA option is considered to be enabled when it was previously setup. For instance, the TOTP set up can be done during the sign-in process when the signIn API returns the CONTINUE_SIGN_IN_WITH_TOTP_SETUP step. It can also be set up when the user is authenticated by calling setupTOTP and verifyTOTPSetup.

In addition, Cognito only allows 1 option to be preferred. This can be achieved by calling the updateMFAPreference API.

Input

V5

user: CognitoUser
params?: GetPreferredMFAOpts {
bypassCache: boolean;
}

V6

No input in v6

Output

V5

'SMS' | 'TOTP'

V6

FetchMFAPreferenceOutput: {
enabled?: ('SMS' | 'TOTP')[];
preferred?: 'SMS' | 'TOTP';
}
import { fetchMFAPreference } from 'aws-amplify/auth';
const getPreferredMFA = async () => {
const { preferred } = await fetchMFAPreference();
return preferred;
}
import { Auth } from 'aws-amplify';
const getPreferredMFA = async ({ user }) => {
const preferredMFA = await Auth.getPreferredMFA(user);
return preferredMFA;
}

Auth.setPreferredMFA

In v6, Auth.setPreferredMFA has been replaced by updateMFAPreference, which can also be used to enable and disable MFA methods. This method accepts an object with the properties sms and mfa, each of which can be set to ENABLED, DISABLED, PREFERRED, and NOT_PREFERRED.

Input

V5

user: CognitoUser
mfaMethod:
| 'TOTP'
| 'SMS'
| 'NOMFA'
| 'SMS_MFA'
| 'SOFTWARE_TOKEN_MFA'

V6

input: UpdateMFAPreferenceInput {
sms?:
| 'ENABLED'
| 'DISABLED'
| 'PREFERRED'
| 'NOT_PREFERRED'
mfa?:
| 'ENABLED'
| 'DISABLED'
| 'PREFERRED'
| 'NOT_PREFERRED'
}
Output

V5

'No change for mfa type' | 'SUCCESS'

V6

No output in v6

import { updateMFAPreference } from 'aws-amplify/auth';
const handleSetPreferredMFA = async () => {
await updateMFAPreference({ totp: 'PREFERRED' });
}
import { Auth } from 'aws-amplify';
const handleSetPreferredMFA = async ({ user }) => {
await Auth.setPreferredMFA(user, 'TOTP');
}

Auth.getMFAOptions (DEPRECATED)

This API has been deprecated and results apply only to SMS MFA configurations: existing use cases can be migrated to fetchMFAPreference (see Auth.getPreferredMFA), which will apply to both SMS and TOTP configurations.

Input

V5

user: CognitoUser

V6

No input in v6

Output

V5

MFAOption[]: {
DeliveryMedium: 'SMS' | ~~'EMAIL'~~;
AttributeName: string;
}[]

V6

FetchMFAPreferenceOutput: {
enabled?: ('SMS' | 'TOTP')[];
preferred?: 'SMS' | 'TOTP';
}
import { fetchMFAPreference } from 'aws-amplify/auth';
const getEnabledMFAOptions = async () => {

const mfaOptions = await Auth.getMFAOptions(user);
const enabled: string[] = [];
for(let option of mfaOptions) {
enabled.push(option.DeliverMedium);
}
return enabled;
}

Auth.signOut

The signOut API has not changed from v5 to v6 other than that it is now a functional API.

Input

V5

opts?: SignOutOpts {
global?: boolean;
}

V6

input?: SignOutInput {
global: boolean;
}
import { signOut } from 'aws-amplify/auth';
const handleSignOut = async () => {
await signOut();
}
import { Auth } from 'aws-amplify';
const handleSignOut = async () => {
await Auth.signOut();
}

Auth.changePassword

The Auth.changePassword API has become updatePassword in v6. It now accepts named parameters as input instead of positional parameters. The input is now an object containing oldPassword and newPassword.

CognitoUser is not required input for updatePassword. All Auth API’s now use the current signed in user information to perform operations, so sending and receiving CognitoUser through every API is no longer required.

Input

V5

user: CognitoUser
oldPassword: string
newPassword: string
clientMetadata?: ClientMetaData {
[key: string]: string
}

V6

input: UpdatePasswordInput {
oldPassword: string;
newPassword: string;
}
Output

V5

'SUCCESS'

V6

No output in v6

import { updatePassword } from 'aws-amplify/auth';
const handleChangePassword = async ({
oldPassword,
newPassword
}) => {
await updatePassword({
oldPassword,
newPassword
});
}
import { Auth } from 'aws-amplify';
const handleChangePassword = async ({
user,
oldPassword,
newPassword
}) => {
await Auth.changePassword(
user,
oldPassword,
newPassword
);
}

Auth.forgotPassword

In v6, the Auth.forgotPassword API has become resetPassword. It uses named parameters instead of positional, so the input will now be an object with username and options (clientMetadata can be passed in options if needed).

Input

V5

username: string
clientMetadata?: ClientMetaData {
[key: string]: string;
}

V6

input: ResetPasswordInput {
username: string;
options?: {
clientMetadata?: {
[key: string]: string;
};
};
}
Output

V5

{
CodeDeliveryDetails: {
AttributeName: string;
DeliveryMedium: string;
Destination: string;
}
}

V6

ResetPasswordOutput {
isPasswordReset: boolean;
nextStep: {

codeDeliveryDetails: {
destination?: string;
deliveryMedium?:
| 'EMAIL'
| 'SMS'
| 'PHONE'

attributeName?: 'email' | 'phone_number';
};
};
}
import { resetPassword } from 'aws-amplify/auth';
const handleResetPassword = async ({
username,
clientMetadata
}) => {
const result = await resetPassword({
username,
options: {
clientMetadata
}
});
const {

username,
clientMetadata
}) => {
const result = await Auth.forgotPassword(
username,
clientMetadata
);
const {
AttributeName,
DeliveryMedium,
Destination
} = result.CodeDeliveryDetails;
}

Auth.forgotPasswordSubmit

Auth.forgotPasswordSubmit has become confirmResetPassword and takes named parameters instead of positional parameters. The expected input is now an object containing username, newPassword, confirmationCode, and options. If needed, customMetadata can be sent through the options property.

Input

V5

username: string
code: string
password: string
clientMetadata?: ClientMetaData {
[key: string]: string;
};

V6

input: ConfirmResetPasswordInput {
username: string;
newPassword: string;
confirmationCode: string;
options?: {
clientMetadata?: {
[key: string]: string;

const handleDeleteAttributes = async ({ attributes }) => {
await deleteUser();
}
import { Auth } from 'aws-amplify';
const handleDeleteUser = async () => {
await Auth.deleteUser();
}

Auth.currentAuthenticatedUser (DEPRECATED)

This API has been deprecated: existing use cases can be migrated to a combination of the getCurrentUser and fetchAuthSession API's.

Also note that we no longer return refreshToken or clockDrift with the AuthSession. These values are used under the hood to refresh/validate the user session.
