How do I turn Face ID on or off?

Go to Profile, then Security. Use the switch on Face ID to unlock and pay. On Android it reads Your face to unlock and pay or Your fingerprint to unlock and pay.

Turning it on asks for your TempDash PIN first, so only you can switch it on. Turning it off doesn’t ask for anything.

If Face ID doesn’t recognise you, or you cancel it, you go straight to your TempDash PIN. Tap Use PIN at any time.

With it off, TempDash still locks, and you open it and move money with your PIN.
