Yep. Or saves the plaintext of the password elsewhere after using it once for a "legit" use.
Rule zero of security is that you can't ask people to forget things. If they had knowledge of a shared secret and they're not supposed to going forward, then that shared secret needs to be changed.
Thats the whole point of audit logs. You lookup the passwords he accessed and only rotate those (vs rotating all of team's shared secrets because you dont know which ones he used/saved/etc).
You're missing the point. The software has no way to tell if a compromised user looked at certain passwords out of band. The audit logs aren't guaranteed to be complete, so you should rotate every key they could have accessed anyway.
No it actually is not the whole point. Security is never convenient. If you do not have an active password rotation automated for all accounts, even shared, then you should be more worried about an employee reporting you to compliance officers. #justsaying
Huh? Its not reasonable to expect automated password rotation for all shared secrets, especially for external services that a team could use. Some passwords will always need to be rotated manually.
