How to Set Up Two-Factor Authentication on Your Accounts

What is Two-Factor Authentication (2FA)?

Two-Factor Authentication, or 2FA, requires you to provide two types of information to access your account:

1. Something you know (your password).
2. Something you have (a verification code generated by a mobile device or app).

This combination makes it much harder for unauthorized users to access your account, even if they have your password.
