If you need to reset your password or change your account details, we will send you a code. When you give the code back to us, we know that you’re really you.
You can get security codes or verify you're you in a number of ways, including email, text message or by using an Authenticator app.
To add an additional way to sign in or verify your account
Sign in to your Advanced security options page using your Microsoft Account.
Select Add a new way to sign in or verify then choose how you would like to receive security codes.
Tip: The email or phone number does not have to be yours - you just need to have access to it if you want to use it to verify your account.
We'll send a security code to confirm. Enter that code when prompted and then select Next.
