On the Android app, and possibly desktop too (I think it is also an issue there, but can’t check at the moment), if you have a particular item set to require re-entry of your master password to edit/view the item’s password, the dialogue which pops up asking you to do this has no option to make the password visible whilst typing. There should be an eye/crossed out eye toggle like there is when you log in, so that you can view the password.
This seems like a big accessibility issue and I’m surprised that an app focused on passwords would be missing this. I guess it was just overlooked? I’ve been being annoyed by this for months but I finally got round to requesting it here after a particularly frustrating episode of entering it wrong repeatedly and having no idea what I was doing wrong.
