A stolen password is the most common way accounts get taken over, through phishing, data leaks or reused passwords. Two-step verification (also called two-factor authentication or 2FA) stops most of these attacks: even with your password, someone can't get in without the second step on your phone or security key.
Your Google, Microsoft and Apple accounts are the most important ones to protect. They hold your email, which is how every other password gets reset. Each takes about five minutes.
Before you start: have your phone with you, and a safe place to write down or store backup codes (a password manager, or paper kept at home).
Add stronger options on the same page:
If your account is managed by work or school, your administrator may control these settings.
Important extras:
Microsoft also lets you go passwordless: sign in with the Authenticator app, Windows Hello or a passkey instead of a password.
Most Apple Accounts created on recent devices already have two-factor authentication turned on. To check or turn it on:
On iPhone or iPad:
On a Mac:
Apple then sends a six-digit code to your trusted devices (devices already signed in to your account) or your trusted phone number when you sign in somewhere new. Add a second trusted phone number, such as a family member's, so you're not locked out if you lose your phone.
| Method | Protection | Notes |
|---|---|---|
| Passkey or security key | Strongest | Works only on the real website, so phishing pages can't use it |
| Authenticator app or sign-in prompt | Strong | Never approve a prompt you didn't start |
| Text message or voice code | Basic | Better than nothing; codes can be intercepted or redirected |
| Backup codes | Emergency only | Store them safely; each works once |
Use the strongest option each service offers, and keep a backup method as well.
Two-step verification is also the first thing to set up after a phishing scare. Read how to spot a phishing email to recognise the messages that try to steal your password in the first place, and the signs your computer has malware if you think your PC itself is compromised.
If you've lost your phone and your backup codes, use each service's account recovery page (Google's account recovery, Microsoft's account recovery form, or Apple's account recovery on iforgot.apple.com). Recovery is slower on purpose, to stop attackers. Give as much accurate information as you can, and try from a device and location you've used before.
For everyday use they mean the same thing: signing in needs your password plus a second proof, such as a code on your phone or an approval prompt. Google and Microsoft call it two-step verification; Apple calls it two-factor authentication.
Passkeys and hardware security keys resist phishing best. An authenticator app or sign-in prompt is next. Text-message codes are better than nothing but can be intercepted or redirected.
Use a backup method: Google backup codes, a Microsoft recovery code or second contact method, or another trusted Apple device or phone number. Set these up on the day you turn on two-step verification.
No. On devices you mark as trusted, you usually only need the second step the first time, or after you sign out, reset the device or change your password.
