Received unrequested single-use code

Question

Received unrequested single-use code

Maricela Guzman 10

Dear MS Team

I have received an email from following address "******@accountprotection.microsoft.com" with subject "Your single-use code"

The email body looks something like "We received your request for a single-use code to use with your Microsoft account."

I did not request anything and thereof I assume this is wrong / spam / scam ... but the sender address looks authentic and I would appreciate a confirmation from Microsoft this request went unauthorized without my consent.

I will highly appreciate your swift and kind reply.

Kind regards

I’ve received the same. I have a feeling it’s an ex partner but I can’t prove it. I’ve changed my password to a very strong password and have since still received another. I’ve checked my recent sign in information and other than my password change there’s nothing there but it’s worrying me.

If the Bad Guys have your email address and it has Sign-In Enabled, there is nothing Microsoft can, or should, do to stop a login attempt. They don't know it's not you trying to logon.

What you can do is setup a Login Only Alias and disable Sign-In for your current email address. For detailed instructions see the answer by "Hornblower409 on Feb 27, 2026" in

Hello, thank you for reaching out to Microsoft Q&A.

This issue has recently been reported by several users.

For reference -

Reddit thread-

Microsoft has implemented several security measures to protect user accounts from unauthorized access and potential threats. However, in some situations, you may still receive emails like this, which can make it seem as though your account is not secure.

So, it is recommended to visit your Microsoft Account Recent Activity page to check for any suspicious activity:

https://account.microsoft.com/security

If you notice anything unusual,

Click "This wasn't me" to report the activity to Microsoft or you will be guided to secure your account.

Regardless, we strongly recommend taking the following steps to protect your account:

Reset your Microsoft account password.
Enable two-factor authentication (2FA) for added security.

Let me know if you still need more help.
