One extra step that blocks most account takeovers. Here's how 2FA works and how to turn it on.

Two-factor authentication (2FA) adds a second check when you log in. Even if someone steals your password, they can't get into your account without that second step.

It takes a few minutes to set up and is one of the best things you can do to protect your accounts.

Types of 2FA

Method How it works Security
Authenticator app An app on your phone shows a new 6-digit code every 30 seconds Strong
Passkey or security key Your device or a physical key confirms it's you Very strong
SMS code A code is sent by text message Better than nothing

How to turn it on

  1. Open the account's Settings and look for Security, Login or Password.
  2. Find Two-factor authentication, 2-step verification or Passkeys.
  3. Choose your method — an authenticator app or passkey if available.
  4. If using an app, scan the QR code with your authenticator app and enter the code it shows.
  5. Save your backup codes somewhere safe.
Don't skip thisBackup codes let you get back in if you lose your phone. Store them in a password manager or print them and keep them somewhere secure.

Which accounts first?

  • Email — it's used to reset other passwords
  • Banking and payment apps
  • Social media
  • Cloud storage with your photos and documents
  • Shopping accounts with saved cards

Stay alert

Never share a 2FA code with anyone, even if they claim to be from your bank or the company. Real companies won't ask you for these codes.

Once 2FA is set up, logging in only takes a few extra seconds — and your accounts become far harder to break into.
