FaceID (or TouchID) is not a replacement for your Passcode. The biometric authenticator provides an alternative method of accessing your device or protected credentials.
Much of your iPad’s advanced functionality simply won’t work unless a Passcode has been set. As documented by Apple in its Security Guide, for devices with TouchID or FaceID enabled, you device Passcode is reportedly required in the following circumstances…
A passcode or password is also required if the device is in any of the following states:
• The device has just been turned on or restarted
• The user has logged out of their Mac account (or hasn’t yet logged in).
• The user hasn’t unlocked their device for more than 48 hours.
• The user hasn’t used their passcode or password to unlock their device for 156 hours (six and a half days), and the user hasn’t used a biometric to unlock their device in
4 hours.
• The device has received a remote lock command
• The user exited power off / Emergency SOS by pressing and holding either volume button and the Sleep/Wake button simultaneously for 2 seconds and then pressing Cancel.
• There were five unsuccessful biometric match attempts (though for usability, the device might offer entering a passcode or password instead of using biometrics after a smaller number of failures).
When Face ID with a mask is enabled on an iPhone, it’s available for the next 6.5 hours after one of the following user actions:
• Successful Face ID match attempt (with or without a mask)
• Device passcode validation
• Device unlock with Apple Watch
Any of these actions extends the period by an additional 6.5 hours when performed.
A forgotten or unknown iPhone/iPad passcode cannot be recovered - and neither can it be reset or modified from another device. If you see a waiting period you can wait and try again to input the correct Passcode; otherwise, the iPad must be restored.
