Setup Wizard: Set Your Blackphone’s Password
Step 5: Set up a PIN or password for your device’s screen lock. You’ll need to enter this PIN or password to unlock your device when you turn on its display.
Choose a PIN or Password to protect your device. If you decide to use a PIN, Blackphone requires a minimum of 5 digits.
Note: Blackphone automatically encrypts your data by default. When you set a screen lock PIN or Password, it will also become your decryption PIN or Password — you will enter it when your phone boots up to decrypt your device storage. However, Blackphone also supports setting up separate decryption and screen lock codes. Please see ” Encryption Password” for more information.
