In android; there is also a ‘lockdown’ mode you can quickly activate from the power off screen, that disables Biometrics until next unlock with a pin/pattern

On iOS, with a locked device, quickly press the lock button five times to do the same, it should bring up the power off/SOS screen, which you can dismiss.

I have used 1Password with the annual plan for years across various browsers and operating systems and have found it to be perfect for everything I need. I will definitely take a look at Proton though.
