What is 2fa?

Two-factor authentication is a security measure that requires two pieces of information to log in to a site or app. The first piece of information is something you know, like a password. The second piece of information is something you have, like a phone or security token.

Two-factor authentication makes it harder for someone to steal your account information because they would need both your password and your phone or security token to log in. This extra layer of protection helps keep your data safe even if your password is stolen.
