What Is Two-Factor Authentication?

Two-factor authentication (2FA) adds an extra layer of security. In addition to your password, you must enter a verification code sent to your phone or generated by an authentication app.

This means even if someone steals your password, they cannot log in without the second verification factor.

Available 2FA Methods in Yahoo

• SMS verification code;
• Yahoo mobile app approval;
• Authenticator apps (such as Google Authenticator);
• Security key (available in some regions).
