Set up password change and recovery

Amplify Flutter v1 is now in Maintenance Mode until April 30th, 2025. This means that we will continue to include updates to ensure compatibility with backend services and security. No new features will be introduced in v1.

Please use the latest version (v2) of Amplify Flutter to get started.

If you are currently using v1, follow these instructions to upgrade to v2.

Reset password

In order to reset your password, use the resetPassword api - this will send a code to the user attribute configured to receive such a reset code (e.g. email or SMS):

Future<void> resetPassword(String username) async {
try {
final result = await Amplify.Auth.resetPassword(
username: username,
);
await _handleResetPasswordResult(result);
} on AuthException catch (e) {
safePrint('Error resetting password: ${e.message}');
}
}
Future<void> _handleResetPasswordResult(ResetPasswordResult result) async {
switch (result.nextStep.updateStep) {
case AuthResetPasswordStep.confirmResetPasswordWithCode:
final codeDeliveryDetails = result.nextStep.codeDeliveryDetails!;
_handleCodeDelivery(codeDeliveryDetails);
break;
case AuthResetPasswordStep.done:
safePrint('Successfully reset password');
break;
}
}

To complete the password reset process, invoke the confirmResetPassword api with the code you were sent and the new password you want.

Future<void> confirmResetPassword({
required String username,
required String newPassword,
required String confirmationCode,
}) async {
try {
final result = await Amplify.Auth.confirmResetPassword(
username: username,
newPassword: newPassword,
confirmationCode: confirmationCode,
);
safePrint('Password reset complete: ${result.isPasswordReset}');
} on AuthException catch (e) {
safePrint('Error resetting password: ${e.message}');
}
}

Change password

A signed in user can update their password using the updatePassword api:

Future<void> updatePassword({
required String oldPassword,
required String newPassword,
}) async {
try {
await Amplify.Auth.updatePassword(
oldPassword: oldPassword,
newPassword: newPassword,
);
} on AuthException catch (e) {
safePrint('Error updating password: ${e.message}');
}
}
