Two-factor authentication ( 2FA ) is an extra step added to the login process. It’s a mechanism to double-check your identity is legitimate and prevent unauthorized access to your account. The first factor is something you know, like your credentials (username and password or PIN), and the second factor is something you have, such as your mobile phone ( SMS ).

When you want to sign in to your Simple account, and you are prompted to authenticate with a username and a password or PIN – that’s the first verification level. Two-factor authentication works as an extra security layer that will re-confirm your identity. This serves as an additional layer of protection to your account and can be done with SMS, email or a special authenticator app.
