What is two-factor authentication and why you should use it
Two-factor authentication (2FA) adds a second layer of security to your accounts. Even if someone guesses your password, they still can't access your account without the second factor — a code from your phone. It's like having a lock and key plus a security guard.
2FA requires two separate pieces of proof before you can access your account. Common methods include SMS text codes, authenticator apps like Google Authenticator, biometric (fingerprint or face), or backup codes. Each method has tradeoffs between security and convenience.
No step-by-step guide available for this issue yet — book a technician directly.
Common mistakes to avoid
- Enabling 2FA and immediately deleting the backup codes
- Not saving backup codes in a safe place — keep them somewhere you can find them even if your phone is lost
- Thinking 2FA is only for banks — email especially deserves 2FA
Signs you need professional help
- You can't find the 2FA setup option on a service
- You lost backup codes and can't access your backup email
- You lost your phone and don't have backup codes — your account is locked
