I keep getting emails for a single-use code.

Hello Priscilla_A,

Welcome to the Microsoft community.

I'm a Microsoft user like you, I hope you're doing well?

I understand how discomforting it can be to receive a one-time security code for your account when you didn't initiate.

However, it's a good idea to ignore this code if you haven't requested it.

One-time code is an essential security feature that prevents unauthorized access to your account. One-time code is required to access your account. These codes can be used only once and has expiration time for their usage.

You may receive one-time code emails if:

1. Signing into your Microsoft account from a new device or browser.
2. Resetting your Microsoft account password.
3. Making changes to your Microsoft account security information.
4. Signing into your Microsoft account from a new location.
5. Unusual and suspicious activity is detected on your Microsoft account.

If someone mistakenly enters your account email ID, you can't stop them, that's out of your control (you don't know who it is), All you can do is ignore it, as suggested in the email.

The same applies if someone may be trying to intentionally access your Microsoft account, a one-time code is a security feature that prevents this unauthorised access.

You don't control the actions of others, hence you can't stop it.

If there was a way to stop it, Microsoft would state it in an email rather than suggesting you to ignore it any one-time code you did not initiate.

I will suggest you check your Microsoft account sign-in activity to make sure there are no unauthorised access. You can see a list of devices and browsers that have accessed your account recently.

Here are a few things you can do to make your Microsoft account more secured:

1. Create a strong password for your account
2. Use the Microsoft Authenticator phone app to sign in without a password
3. Make your account easier to recover
4. Make sure your operating system has the latest updates
5. Never reply to email asking for your password
6. Check your recent activity
7. Keep your devices safe
