The Microsoft account team will sometimes ask you to verify your account. We do this to help prevent a hacker from accessing your sensitive info by pretending to be you. But if all of your security info is incorrect or out of date—for example, if you no longer use any of the phone numbers or alternate email addresses associated with your account—you need to delete the out-of-date info and update your account.
Go to the Security info page and sign in to your Microsoft account.
If you're prompted to enter a security code, tap or click Use a different verification option.
Choose I don't have these any more from the drop-down list, and then tap or click Next.
Follow the instructions on the screen to add and verify new security info.
Please note that we don't fully delete any of your old info for 30 days, and you won't be able to sign in to your Microsoft account with the new info you add until the 30 days have passed. We're sorry for any inconvenience, but this waiting period helps to deter hackers from updating your security info and gaining access to your account without your knowledge.
