If you use Touch ID and you do any of the following:

  • replace your device,
  • change a safe name,
  • change a safe location (local vs iCloud),
  • update Touch ID (by adding a face/fingerprint),
  • reset Touch ID.

The saved password will be lost - so before you do this make sure you remember your safe password.

If you have forgotten your safe password, you can change the password while Touch ID is still working.
