The Blockstream app's Security tab allows you to change how you unlock your wallet, back up your recovery phrase, and more.
On the Security screen, you can access your recovery phrase and alter your preferred unlock method:
- FaceID: If you'd like to use FaceID to unlock your wallet, make sure it is enabled in your device's system settings first. You must turn on FaceID at the operating system (OS) level for it to work within the app.
- PIN: The PIN is a locally stored security feature. It will not transfer across devices—even if you're restoring your wallet on a new phone. You’ll need to set up a new PIN after restoring with your recovery phrase.
Note: In addition to keeping your PIN number and recovery phrase hidden from others, it's also important to properly back them up for your own use. Remember, you will lose access to your bitcoin and other assets if you are unable to unlock your wallet and do not have access to your recovery phrase.
