Two Factor Authentication on Gmail and YouTube

Why you need it

It's easier than you think for someone to steal your password

Any of these common actions could put you at risk of having your password stolen:

  • Using the same password on more than one site
  • Downloading software from the Internet
  • Clicking on links in email messages

2-Step Verification can help keep bad guys out, even if they have your password.

Why you need it

Imagine losing access to your account and everything in it

When a bad guy steals your password, they could lock you out of your account, and then do some of the following:

  • Go through – or even delete – all of your emails, contacts, photos, etc.
  • Pretend to be you and send unwanted or harmful emails to your contacts
  • Use your account to reset the passwords for your other accounts (banking, shopping, etc.)

How it works

Signing in to your account will work a little differently

You’ll enter your password

Whenever you sign in to Google, you’ll enter your password as usual.

Then, a code will be sent to your phone via text, voice call, or our mobile app. Or, if you have a Security Key, you can insert it into your computer’s USB port.

How it works

Keep sign-in simple

During sign-in, you can choose not to use 2-Step Verification again on . From then on, that computer will only ask for your password when you sign in.

You’ll still be covered, because when you or anyone else tries to sign in to your account from , 2-Step Verification will be required.

How it Protects

An extra layer of security

Most people only have one layer – their password – to protect their account. With 2-Step Verification, if a bad guy hacks through your password layer, he’ll still need your phone or Security Key to get into your account.

Sign in will require something you know and something you have

With 2-Step Verification, you’ll protect your account with something you know (your password) and something you have (your phone or Security Key).

Verification codes made just for you

Codes are uniquely crafted for your account when you need them. If you choose to use verification codes, they will be sent to your phone via text, voice call, or our mobile app. Each code can only be used once.

Two Factor Authentication on Facebook

Two Factor Authentication on Facebook

Two-factor authentication is a security feature that helps protect your Facebook account in addition to your password. If you set up two-factor authentication, you’ll be asked to enter a special login code or confirm your login attempt each time someone tries accessing Facebook from a browser or mobile device that we don’t recognise. You can also get alerts when someone tries logging in from a browser or mobile device that we don’t recognise.
To turn on or manage two-factor authentication:
  • Go to your Security and login settings.
  • Scroll down to Use two-factor authentication and click Edit.
  • Choose the security method that you want to add and follow the on-screen instructions.
When you set up two-factor authentication on Facebook, you’ll be asked to choose one of three security methods:
Other useful resources
  • If you haven’t saved the browser or mobile device that you’re using, you’ll be asked to do so when you turn on two-factor authentication. This way, you won’t have to enter a security code when you log in again. Don’t click Save this browser if you’re using a public computer that other people can access (e.g. a library computer).
  • We need to be able to remember your computer and browser information so that we can recognise it the next time you log in. Some browser features block this. If you’ve turned on private browsing or set up your browser to clear your history every time it closes, you might have to enter a code every time you log in. Learn more.
  • To set up text message (SMS) two-factor authentication, you can either use a mobile number that’s already been added to your account or add a new number. Learn more about how Facebook uses a mobile number added for two-factor authentication.
