Gem Wallet now offers to turn on Face ID, fingerprint, or a passcode right after you create or import a wallet, if app lock is still off. The screen has been live for our users on iOS and Android since October 1, 2026, in version 2.114.57 - you turn on protection with one tap, right at the start.
What Is App Lock in Gem Wallet?
App Lock is a Face ID, fingerprint, or passcode check every time you open Gem Wallet. Without it, anyone who picks up your unlocked phone can see your wallet and balances.
Now Gem Wallet offers to turn on the lock once - at the moment your wallet is ready. For example, you create a Bitcoin Wallet, and on the next screen Gem Wallet offers to turn on Face ID - from the first minute, only you can access your assets.
How Gem Wallet Locks the App
- Face ID and Touch ID: On iPhone and iPad, the button on the screen names the method set up on your device.
- Android Biometrics: Fingerprint or face unlock, as set up in your phone’s system.
- Passcode: If there are no biometrics, Gem Wallet offers your device passcode.
Benefits for Gem Wallet Users
Gem Wallet is a mobile self-custody wallet with 100% open-source code for iOS and Android. Here are its main benefits:
- Full Self-Custody: Your private keys stay on your device - only you sign transactions, and no intermediary ever touches your assets.
- Fully Open-Source Code: Gem Wallet’s code is 100% open and passed a CertiK audit in April 2026 - anyone can check how the lock works.
- Privacy by Default: No sign-up needed - no email, phone number, or ID, and Gem Wallet collects no personal data.
- Protection From the First Minute: The lock turns on right after you create or import a wallet, not whenever you happen to remember it.
- Biometrics Stay on Your Phone: Your device’s system checks your face or fingerprint, and Gem Wallet only gets a “confirmed” answer.
- Shown Once: The screen appears only once - you can skip it and turn on the lock later in settings.
- Simple and Clear Interface: The app is easy to figure out from the first seconds - every feature is at hand, and it works equally well for crypto beginners and experienced users.
How to Enable Face ID in Gem Wallet
