Two-factor authentication (2FA) adds an extra layer of security to make sure you are the only user who can access your account. 2FA makes it harder for attackers to gain unauthorized access, since it requires an additional code beyond your password.

You must install an authenticator app on your phone to generate these one-time codes. The three most popular authenticator apps for both Android and iOS are:

1. Google Authenticator
2. Authy
3. LastPass Authenticator

Use your chosen authenticator app to scan the QR code provided during the account creation process.
