I ran into a lot of annoyance with 1Password because they had a glib stance on their generator. It would have commas and a bunch of random characters, special characters at the front of a password, etc. which many sites - albeit arbitrary- didn’t like.
I’m for practicality of not getting ‘we don’t accept passwords that look like computer code’ rather than taking a stance that a password field should accept any character I throw at it. After all, if you change a password from OIlk*(j343 to OIlk,(j343 the hash would be entirely different. Brute forcing is just a series of guesses until one cracks the puzzle and its complexity is just based on assumptions and looking for the lowest hanging fruit. The person with a password of monkey123 is screwed compared to you.
Back to 1Password, the problem with there’s was that it would immediately pop up to update your password. If the site didn’t like the password it generated I couldn’t exit out and fill my current password back in because it had been updated. Consequently I had to do a lot of opening Notepad and pasting new passwords, then going into my vault and updating it with the password the site would take.
