I meant you can auto-type (or Ctrl+V) from Keepass, usually. You go into Keepass, say “Open URL”, and go back to Keepass and say “Auto-Type”. Or yes, if you’re on the page, Ctrl+Alt+A should do the same thing.
The nice thing , IMO, is that you can set up Auto-Type to do other actions besides the default “username->tab->password”
Well, the alternative is what? Memorize them all? Like I said, password managers are encrypted, breaking into them is not trivial. If it’s gotten to that, your stuff is likely all compromised already, anyway.
Make the main password something you won’t forget. If even the CorrectHorseBatteryStaple method doesn’t work for you, try something like the first verse of your favourite song.
Yes, I said verse.
As for switching PCs, no, you keep the same keyfile, that’s what the master password unlocks.
