Hi, I use KeepassXC and have a good, long master password which I know by heart. In my experience, if you use it regularly, this should not be an issue.

It is on a mobile device with fat fingers.
Amusingly, if this was back in the days of hardware keyboards on phones, like my G1 or G2, this would be less of an issue, as I would not have any issues banging out an accurate password on a phone when needed. I pretty much rely on swipe typing. My thumbs are not made for typing on tiny keys.
