Hi,

Please do not enter or share any Microsoft verification code that you did not request. Unrequested codes can mean someone is trying to sign in to an account using your phone number/email, or that someone entered your details by mistake.

Please go directly to account.microsoft.com/security, review your recent sign-in activity, update your password if needed, and make sure your security info is correct. Also, do not approve any Microsoft Authenticator prompt unless you initiated the sign-in yourself.

If you have multiple Microsoft-related accounts, such as Outlook, Hotmail, Live, Xbox, Skype, OneDrive, or Microsoft 365, check each one because the phone number may be linked to an older account.

Hi billie

Based on the information you provided, receiving Microsoft authentication verification codes that you did not request does not necessarily indicate that your account has been compromised.

Since you have already reviewed your account activity and confirmed that:

The only successful sign-ins shown are your own.

There are no sign-in events corresponding to the dates and times when the SMS verification codes were received.

this is a positive indication that there has not been any successful unauthorized access to your account.

There are several possible explanations for these messages:

Someone may have entered your phone number by mistake while attempting to sign in or recover an account.

Someone may be attempting to initiate a sign-in process using an account associated with your phone number.

Microsoft users have previously reported instances of receiving unsolicited verification codes without corresponding suspicious sign-in activity being recorded. (Why are multiple users receiving unrequested OTPs via text even if their default MFA is Authenticator app?)

As a precaution, I recommend the following:

Continue monitoring your account's Recent Activity page for any unfamiliar sign-in attempts.

Verify that your security information and authentication methods are up to date.

Ensure your password is strong and unique. If you have any concerns, consider changing it.

Never share verification codes with anyone, regardless of the reason they provide.

If you receive unexpected authentication prompts through the Microsoft Authenticator app, be sure to deny them.

It is also worth noting that not every authentication or account verification attempt will appear as a completed sign-in event in the Recent Activity log. Therefore, it is possible to receive a verification code without seeing a matching entry in the sign-in history.

At this time, based on the information provided, there is no indication that your account was successfully accessed by an unauthorized party.

I hope this information is useful. Additionally, as other users have raised similar concerns and may not be aware of where to share their feedback, I hope this response helps clarify the situation and suggests a potential next step. Highlighting this information can make it more visible to others in the community who may be facing the same issue, making it easier for them to find guidance and contribute their feedback as well.

Thank you again for your time and for raising this important usability concern. If you have any further questions or need additional assistance, please don’t hesitate to reach out.

I look forward to your thoughts on this.

If you are receiving Microsoft verification codes by SMS that you did not request, it is possible that someone is attempting to sign in to your Microsoft account using your phone number or is entering it by mistake. Receiving the codes alone does not mean your account has been accessed, as the verification code is intended to prevent unauthorized sign-ins.

As a precaution, sign in to your Microsoft account and review your recent sign-in activity for any unfamiliar attempts. If you notice suspicious activity, change your password immediately and ensure two-factor authentication is enabled. If you no longer recognize which Microsoft account is associated with your phone number, try recovering your account using your known email addresses or contact Microsoft Support for assistance.

As long as you do not share the verification codes with anyone, your account remains protected. I hope this helps.
