What is Two-Factor Authentication (2FA)?  

Two-factor authentication (2FA) adds an extra security step when you log in. It requires something you know (password) and something you have (code or device).

Even if someone steals your password, they can’t access your account without the second step. This makes your accounts:

• Much harder to hack

• Better protected against leaks

• Safer overall

Common 2FA methods:

• SMS codes

• Authenticator apps

• Email verification

• Physical security keys
  
  

Example: You log in → enter password → receive a code on your phone → access granted.
