Enable guest access

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.

The AWS Cognito Auth Plugin can be configured to automatically obtain guest credentials once the device is online so that you are able to use other categories "anonymously" without the need to sign in. You will not be able to perform user specific methods while in this state such as updating attributes, changing your password, or getting the current user. However, you can obtain the unique Identity ID which is assigned to the device through the fetchAuthSession method described here.

Follow these steps to enable guest access on your Auth category:

amplify update auth
What do you want to do?
❯ Walkthrough all the auth configurations
Select the authentication/authorization services that you want to use:
❯ [choose whatever you initially selected - default is User Sign-Up, Sign-In, connected with AWS IAM controls]
Allow unauthenticated logins? (Provides scoped down permissions that you can control via AWS IAM)
 I want to learn more.
 [proceed through the rest of the steps choosing the values you want - default is usually "No"]

To push your changes to the cloud, execute the command:

amplify push

That's it! Now as long as you are online, you will automatically gain guest credentials (which are then cached for offline use as well).
