The 4 digit passcode entry screen looks as it does to the left. This screen appears when the TenX Wallet app is sent to the background and stays there for a certain period of time.
This passcode is not permanently stored; a new one is set on every login.
If your device is has fingerprint login already set up, you can dismiss the passcode entry screen using your fingerprint.
If your device is set up for Apple FaceID recognition, you can use FaceID to dismiss the passcode entry screen.
If you are unable to remember your 4 digit lockscreen passcode, restart your device. This will log you out of the TenX Wallet app as well as clear all cookies involved.
You may then log into the TenX Wallet app again, and be allowed to set up a new 4 digit passcode.
