Depending on your mobile device’s OS, you can unlock your Keplr Wallet using fingerprint recognition or Face ID. This article explains how to enable and disable biometric authentication.
If you enable biometric authentication and, for any reason, it stops working while you’ve also forgotten the password set on Keplr Mobile, you will not be able to unlock your wallet. In such cases, you may need to delete the app and re-import all your accounts. Therefore, even if you use biometrics, make sure to securely store your mobile app password.
Open Keplr Mobile and enter the Settings page from the bottom navigation bar.
Go to the Settings page and find [Use Biometric Authentication] under Security & Privacy. Toggle it on or off to enable or disable the option.
