Two-factor authentication adds a second step when signing in, making your account much harder to compromise.

1. Install an authenticator app such as Microsoft Authenticator, Google Authenticator, or Authy.
2. In your account security settings, choose Enable 2FA.
3. Scan the QR code with your authenticator app.
4. Enter the 6-digit code to confirm, then save your backup codes somewhere safe.

Never share your codes with anyone — IT will never ask for them.
