You may be using password managers to securely store your passwords and other information, but what happens if your master password gets discovered (perhaps through keylogging or maybe someone found that post-it note with it written on it)? Well 2FA can definitely assist with this dilemma. 2FA is an extra security step (something you have) in addition to your password (something you know). In general 2FA is a time-based code that is regenerated every so many seconds. It can be software-only (such as [Google Authenticator][play-store-google-authenticator or Authy, or hardware backed (such as a Yubikey). The reason 2FA is so beneficial is that even if your password (master password for your password manager or passwords for online accounts) is compromised, they will not be able to log in to your accounts without the 2FA code. Even if they have access to your 2FA key (especially a Yubikey), if you have set up a password on the 2FA application they still won’t be able to access your accounts. Good security practices utilise a layered approach so that if one layer becomes compromised all is not lost.
