Two-factor authentication (2FA), also called two-step verification, adds an extra layer of security to your accounts. Even if someone steals your password, they cannot log in without the second factor, such as a code from your phone or a security key. Enabling 2FA is one of the simplest and most effective ways to protect your online life.
How 2FA Works
| — | — |
|---|---|
| Something you have | Phone, authenticator app, security key |
2FA requires two of these, usually your password plus something you have.
Types of 2FA Methods
| — | — | — |
|---|---|---|
| Security keys / passkeys | Very strong, phishing-resistant | Requires compatible devices |
Which Accounts to Protect First
- Email accounts (they can reset other passwords)
- Banking and payment apps
- Social media accounts
- Cloud storage
- Website hosting, domain and WordPress admin accounts
- Work accounts
General Steps to Enable 2FA
- Sign in to the account and open Security or Privacy settings
- Find “Two-factor authentication” or “2-Step Verification”
- Choose your preferred method
- For authenticator apps, scan the QR code and enter the generated code
- Save backup codes securely
- Confirm the setup
Using an Authenticator App
Authenticator apps generate time-based codes that change every 30 seconds. They work without mobile network signal and are more secure than SMS. Back up or transfer codes when changing phones.
Passkeys
Many services now support passkeys, which let you sign in using your device’s screen lock or biometrics instead of passwords. Passkeys resist phishing and are convenient. Consider enabling them where available.
Protect Your Backup Codes
Backup codes let you access your account if you lose your phone. Store them in a password manager or print them and keep them somewhere safe.
Beware of 2FA Scams
Never share 2FA codes with anyone, even if they claim to be support staff. Legitimate companies will not ask for your codes. Reject unexpected login approval prompts.

Two-factor authentication dramatically reduces the risk of account takeover. Enable it on your most important accounts, prefer authenticator apps, security keys or passkeys, store backup codes safely and never share verification codes.
