I use 1pass on my phone. I have a long password (English phrase) that I only use with 1pass I guess I've entered it enough times on mobile that I don't mistype it often.

I use it to generate new passwords for whatever signups/apps I need on mobile, also for logging into websites on mobile. The workflow for password managers in mobile safari works very well.

I don't enable FaceID/TouchID/PIN for 1Password, but I do have it enabled for my device.
