In addition to protecting your Security Space, you can also restrict access to UPDF itself by adding a passkey to unlock the app. This way, only users who know the passkey code will be able to open UPDF and access its contents.

How to Set a Passkey for UPDF

  • Tap the UPDF logo icon on the top left.
  • Tap the “Security” option.
  • Toggle the “Passkey Lock” option to the “On” position.
  • Enter a passkey code of your choosing in both fields and “Confirm”. You can enable Face ID too.

Note: Please remember this code for future access. You will need to enter it whenever you access UPDF.
