"Using unique passwords for every web login means that if your account information ends up in a data breach, it won’t give bad actors an easy way to unlock your other accounts. Since it’s impossible for all of us to remember a unique password for every login we have, most people will want to use a password manager, which generates and stores those passwords for you.Two-factor authentication is the second lock on those same accounts. In order to login to, say, Facebook for the first time on a particular computer, you’ll need to provide a password and a “second factor,” usually an always-changing numeric code generated in an app or sent to you on another device. This makes it much harder for someone else to get into your account because it’s less likely they’ll have both a password and the temporary code."eff.org/deeplinks/2025/09/opt-#Privacy #CyberSecurity
