Important Almost all Mobile Publisher apps were moved to the External Client App framework in the Summer '25 release. If your app is one of a few still using Connected Apps, [refer to the help documentation](https://help.salesforce.com/s/articleView?id=xcloud.connected_app_overview.htm&type=5&language=en_US) for any customizations you need to make.

Mobile Publisher apps support biometric ID app unlock using face or fingerprint credentials when the biometric authentication method is available on the Android or iOS device. Depending on the mobile device, Mobile Publisher also supports Swipe and PIN unlock.

When you enable biometric ID app unlock, users are prompted for their biometric credentials when they open the app with a cold start. A cold start is when the user opens the app for the first time or opens the app after closing the app entirely (swiping up to quit the app). If the user has no security settings enabled, they’re forced to log out of the app.

If you enable the Biometric ID App Unlock feature alone without the [User Opt-In Biometric Login](https://help.salesforce.com/s/articleView?id=xcloud.branded_apps_exp_opt_in_biometric_login.htm&release=264.0.0&type=5 "With User Opt-In Biometric Login, your Mobile Publisher for Experience Cloud app users can easily and securely log in to your app using face or fingerprint recognition.") feature, users can’t log in to your app without configuring biometric login.

Important Remember to wrap attribute values in quotation marks.

1. From Setup, in the Quick Find box, enter External Client App Manager, and then select **External Client App Manager**.
2. Select the external client app that you want to enable biometric ID unlock for.
3. In the Custom Attributes section, click the add button.
4. For the attribute key, enter ENABLE\_BIOMETRICS\_UNLOCK. For the attribute value, enter “TRUE”.
5. Save your changes.

After you enable biometric ID app unlock, your app users must configure their devices to enable unlocking apps with biometric ID credentials in order to use this login method.

If Android app users don’t configure their biometric ID credentials, they’re prompted to proceed with one of these options: log out, log in on a browser, log in with a passcode, or to open their device’s settings.

If iOS app users don’t configure their biometric ID credentials, they’re prompted to log in with a passcode. If the iOS app user doesn't have biometric ID app unlock or passcode unlock configured on their device, the user is prompted to enable a passcode.
