Use the "passwords" feature to check if one of yours is compromised. If it shows up, never ever reuse those credentials. They'll be baked into thousands of botnets etc. and be forevermore part of automated break-in attempts until one randomly succeeds.
You can right click any password field in Chrome and the first option is "generate random password".
2 Issues are the they (1) it is unreadable by humans instead of being a passphrase, and (2) The generator does not read any rules off the page so you might have to add a special character.
But the functionality has existed for over a decade
@Rooster326 @1984 it also asks if you would like to generate a secure password, rather than it just being on right-click, in most "new password" fields.
Google password manager also warns you if you have duplicated passwords saved in it and prompts you to create new, unique ones.
I don't like Google but they do ok with password management I think.
