something I did before letting bitwarden take over my passwords, was using a phrase consisting of 2-3 words + a series of numbers and special characters. Safer than anyone I knew at the time's passwords. Admittedly it was not the most secure, as i only changed the beginning part of the 2-3 word phrase, and left the last word, numbers and symbols the same. So if one of those passwords were breached, it wouldn't be too difficult for AI to brute force the missing pieces. So yeah I don't do that anymore.
