God bless KeePass. Never have to deal with these. I just double click and ctrl+v whenever I need to use a pass. Takes extra 3 seconds but I feel like I am not giving anything to the browsers to save.
Now your security issue is other applications accessing your clipboard.
I'm quite aware of this ever since Samsung/Android started adding a whole interface for the clipboard and added integration with the keyboard (it shows some codes in the clipboard sometimes so you can quickly paste). Can the clipboard be accessed from other apps in the background? Probably?
This is less secure than autofill, though it automatic autofill. At least autofill won’t enter your password for office.com on off1ce.com, though it’s possible that a human be fooled by a lookalike URL.
