Security info confirms your identity
Security info is an alternate contact email address or phone number that you add to your account. If you forget your password, or if someone else is trying to take over your account, we send a verification code to that alternate email or phone number. When you give the code back to us, we know that you’re really you so we can help get you back into your Microsoft account.
We use your security info only to verify your identity if you're accessing personal information or if we detect a problem with your account.
This article is about security info. If you have lost, forgotten or have other password issues, see Change or reset your Windows password.
Before we start into how to manage your security info, let's make sure we’ve successfully sent your verification code.
Manage your security info
You can change your password, update info, or review recent activity. If you're not already signed in to your Microsoft account, you'll see a prompt.
On your Security basics account page, you can add, update, or remove security info. Select any of the following to find out how.
If you request removal of all security info in your account, the info doesn’t actually change for 30 days. During this time, we cannot accept further changes or additions to security settings or billing info. Your account is still open and active, and you can still use your email, Skype, OneDrive, and devices as usual. We’ll let you know when it's time to enter new security info.
