I am being inundated with New Sign In Requests to my Microsoft account. Day and night my phone is buzzing every 10 minutes or so. It has gotten to the point where it is disruptive. It is clear this is a scheme to fraudulently gain access to my account. How can I stop this?

    Do not approve any sign-in prompt that was not initiated. Select Deny on unrequested prompts.

    To reduce the ongoing prompts and secure the account:

    1. Change the account password immediately If there is any chance the account is being targeted, change the password and review security settings.
    2. Review recent sign-in activity Go to the Recent activity page and check for unfamiliar sign-ins, devices, browsers, or locations. A location alone can be misleading because IP-based location can be inaccurate, especially on mobile networks. If any activity is not recognized, secure the account and change the password.
    3. Use stronger sign-in methods For personal Microsoft accounts, Microsoft is phasing out SMS for authentication and recovery. Prefer passkeys, verified email, or Microsoft Authenticator instead of SMS.
    4. Avoid repeated verification attempts Repeated requests for codes or repeated sign-in attempts can trigger temporary blocks or delay verification delivery. If blocked, avoid repeated retries.
    5. If verification is blocked, try these recovery steps
      • Try another verification method already connected to the account.
      • Try another network, such as switching between Wi‑Fi and cellular.
      • Wait 24 hours before retrying; if needed, wait longer, up to 1 week.
    6. If the account is temporarily blocked Unblock it by resetting the password.
    7. If access to security info has been lost
      • If access remains to at least one security method, add a new sign-in or verification method in Advanced security options, confirm it, then remove the old one.
      • Do not change all security info at once. That can restrict the account for 30 days.
      • If access to all security info is lost, start sign-in, select I don't have any of these, and follow the replacement process. After replacement, there is a 30-day wait before sign-in is allowed.
    8. If prompts continue even after password changes A practical way to reduce repeated prompts is to change the sign-in alias used for the Microsoft account, make the new alias the primary sign-in alias, and disable sign-in for the old alias while keeping it for email. This can stop repeated sign-in attempts against the old exposed sign-in name.

    If the account is a work or school account, review sign-in activity in My Account under Recent Activity and update Security info if suspicious activity appears.
