autologin 0.2.0

This Plugin helps the developer to auto login into their app as simple as possible.

This package helps the user to login quickly. When the user has saved in the platform specific password manager credentials will be filled out by a simple confirmation or account chooser depending on the platform. You can also save the users credentials with a simply API call. On supported platforms those credentials will be synced on all your devices.

On Android and Apple devices you can also store a login token to sign in seamlessly without any interaction. So when your user uses your app on a new device for the first time your user will be already signed in.

    

You can check the web example app on the GitHub page in supported (Chromium based) browsers.

Features and compatibilities

*) It seems that saving is just supported on iOS
**) Just on chromium based browsers
***) The documentation of the API mentions that a "Pro" Version is required

The technical implementation details can be found in the corresponding package.

Compatibility checks

If you want to check if the platform you are currently using is supported you can call AutologinPlugin.isPlatformSupported. If you need a full report of all capabilities you can call await AutologinPlugin.performCompatibilityChecks() this will return the Compatibilities with the fields:

• isPlatformSupported
• canSafeSecrets
• canEncryptSecrets
• hasZeroTouchSupport
• hasOneClickSupport

So you can know if the required feature is usable at your current platform at runtime. Even if you call the possible unsupported methods of the next API they should not crash, instead they just do nothing or may return null.

Credentials

Credentials can be saved by using AutologinPlugin.saveCredentials(...) and requested by AutologinPlugin.requestCredentials().

Login Token

The Login Token can be a refresh token or anything else which you can use to identify the user. You should validate that this token is still valid before authenticating the user. Depending on your use case asking for a second factor would be a good idea.

The Login Token can be requested with AutologinPlugin.requestLoginToken() and saved with AutologinPlugin.saveLoginToken('yourToken');.
