Turn on two-step sign-in for email and banking

With two-step sign-in on, a leaked password alone is no longer enough to sign in on that account: the service also asks for a code or a confirmation on your device. Free.

How to do it

  1. Open the security settings of your email account first: whoever controls it can reset most other passwords.
  2. Turn on two-step sign-in (2-step verification); prefer an authenticator app or a passkey over text-message codes.
  3. Do the same for banking, shopping and social media accounts.
  4. Save the backup codes the service gives you and keep them offline.
