A Clear Admin Login Cookies button or /url

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.

I think what you want is already implemented in the upcoming Pi-hole v6 where you can delete every single session.
