I saw this screen a few days ago in the app. Please don’t force me to use FaceID to open the app. I use all of your real security measures when making payments. Enabling FaceID to open the app isn’t real security, it’s security theatre. It also prevents me from using Monzo from my Mac via iPhone Mirroring. If anyone wants to require FaceID to open any app, iOS already supports that feature. Tap and hold an app icon and “Require FaceID” can be selected for any app.
If you turn it off, it forces you to enter your pin on launch. I don’t want either. I want read-only access without security, and security forced only if I try to change account or security settings, or make a payment.
