Recently ran into issue of having password remembered for 7 days and couldn't log in.
From cli I reset password but browser still refused to let me log in with the reset password.
Blank password from cli I could log in.
Even putting a simple Hello123456 password I could not.
I could log in in incognito mode, or from a different browser so I know the password was correct.
Manually clearing browser cache fixed the issue, but having either a clear cookies button on the login page or a url like /clearcookies would be nice for people that get into that situation.
