This method fails as soon as you have to change a password:<p>- One of the sites is compromised<p>- One of your devices is stolen&#x2F;lost and you have to change some passwords<p>- One of the sites has a password expiration policy<p>Pretty soon you end up with multiple password schemes and you&#x27;re in precisely the same situation as before, wondering which password goes with which site, only this time you have to perform algorithmic dances in addition to memory feats.
