Unlock

Once you open the app, you will need to unlock it. The app uses your device configured authentication method to unlock. This can be either a passcode or biometric authentication.

Once the app is unlocked, you can proceed with completing the onboarding instructions.

You will need to use your device unlock method every time you access the app and for any interactions that require authentication.

Setup

You will be prompted to enable push notifications, as the app can notify you when new credentials are available or when the status of an existing credential has changed.

If you choose not to enable push notifications during onboarding, you can do so later by accessing the Settings menu and setting Notifications to On under General.
