How to Fix Keep Getting Microsoft Single Use Codes Emails (2025)

Are you keep getting Microsoft Single Use Codes Emails? If yes then don’t worry you are at the right place.

A single-use code is a verification code that Microsoft sends to your registered email or phone number to confirm your identity when you sign in to your Microsoft account. 

This is a security feature that helps protect your account from unauthorized access.

However, if you receive multiple single-use code emails that you did not request, it may indicate that someone else has your password and is trying to log in to your account. 

This is a serious issue that you need to address as soon as possible.

In this guide we will show you how you can stop getting Microsoft single-use code emails and secure your account.

Fix Keep Getting Microsoft Single Use Codes Emails

Here are some steps you can take to address the issue:

Check Email is Really From Microsoft:

First, check if the email is legit or not.

Make sure they are from Microsoft and not from a phishing source. 

Do not reply or click on any links, or enter any codes from suspicious emails. 

Report them to Microsoft if you suspect they are fraudulent.

Change Your Password:

This will prevent anyone who has your old password from accessing your account.

Here how to change your password:

  • Go to the microsoft website and sign in to your account. 
  • Click on the Security tab and then on the Change password link. 
  • Create a strong and unique password that you do not use for any other account. 

Enable Two-step Verification: 

This is an extra layer of security that requires you to enter a code in addition to your password when you sign in from a new device or browser. 

You can choose to receive the code via email, phone, or an authenticator app. 

To enable two-step verification, 

  • Go to the Microsoft website and sign in to your account. 
  • Click on the Security tab and then on the More security options link. 
  • Under Two-step verification, click on the Set up two-step verification link and follow the instructions.

Change Your Primary Alias: 

Your primary alias is the email address or phone number that you use to sign in to your Microsoft account. 

If you keep getting single-use code emails, it may mean that your primary alias is compromised or used by someone else as a recovery option. 

Follow the steps to change your primary alias: 

  • Go to the microsoft website and sign in to your account. Click on the Your info tab and then on the Manage how you sign in to Microsoft link. 
  • Under Account aliases, click on the Make primary link next to the alias that you want to use as your primary alias. 
  • You may need to verify your identity with a code before you can make the change.

Note that changing your primary alias does not delete or remove your other aliases. 

You can still use them to sign in or send and receive email. 

However, some Microsoft services and devices may take up to 48 hours to sync the change, so you may need to sign out and sign back in with your new primary alias.

These were some steps you should take to ensure the safety of your account or avoid getting those emails.
