I keep getting single-use codes for an email of mine

I have been receiving everyday a single use code to sign into my account with an email of mine -- I have had this email for over 15 years -- someone is trying to get into it. it has a phone number listed with the last digits being 80. my number has NEVER been that. I don't understand how I cannot reset my password without sending a code to that number. this is really starting to piss me off... especially since there isn't a number I can call to contact an actual person. I have gone through putting in my information to try and recover the account, yet it says I didn't provide enough evidence supporting my claim of ownership to this email.

    There's no need to delete the email address, just create a new one and use that specifically for signing into outlook and disable the ability to sign in with the other one. The email will still be active, you just won't be able to use it to sign in.

    I appreciate your response Steve.

    But this is confusing and I consider myself fairly good with this stuff.

    Are you saying if my email is used as my login into certain hacked sites to use a new email?

    Just AI garbage spat at us like it’s helpful. Who do these people think they’re fooling?

    For anyone having this issue in 2025, here is a guide on how to get rid of the single-use code emails:

    https://www.yourwindowsguide.com/2025/04/microsoft-single-use-code-email.html

    Hiding or disabling the sign-in capability for your email would get rid of the single-use code emails. Hiding it would mean that it is not possible to log in using the same, but you can use it for emailing. For that, do the steps below:

    • Make a new Alias for login purposes at this link.
    • Next, fix this alias as the primary alias at https://account.live.com/names/manage page.
    • Now, the next step is to disable the sign-in capability for the the original email, which is possibly hacked in a data breach. Concurrently, You can manage that on this page. Uncheck the Email and click Save.
    • Furthermore, as expected, you can still send and receive email from the old Alias – you have just disabled the capability of it to sign in. Remember to keep the new alias secret or use elsewhere. The dropdown on Outlook apps, like Android and Outlook New on Windowswould show you all your addresses to send an email from.
    • Now, when someone would try to use the breached address, they will hit an error. The error message would say that the Email does not exist.

    This just happened to me right now, and when I checked the email, there is now an email account that I don't know about and who it belongs to. I changed my password and removed that email, but when I logged in on a different device, it is still there and is stated as the current security info.
