Hey there! It sounds like you’re getting frequent push notifications from your Authenticator app because someone (or something) is repeatedly trying to sign in to your Microsoft account. Here’s what you can do to lock things down and tame all those alerts:

1. Review Recent Activity
   • Go to https://account.microsoft.com/security and click Review activity.
   • Look for any unfamiliar locations, devices or IPs and be sure to Deny anything you don’t recognize.
2. Change Your Password
   • While in your security dashboard, pick Change password and choose a strong, unique one.
   • This immediately invalidates any active sessions using the old credentials.
3. Update or Remove Authenticator Registrations
   • Stay on the security page and select Advanced security options (or Security info).
   • Under your Microsoft Authenticator entries, you can: • Remove any old/stale devices you no longer use • Change your default sign-in method from “App notification” to “Verification code” if you still want 2FA without the pushes • Re-add only your current phone/device so nothing else can trigger notifications
4. Add or Tweak Other MFA Methods
   • Consider adding SMS, email or a hardware security key as backup methods.
   • Having multiple methods means you can disable push notification sign-in entirely if you prefer.
5. Turn on Number Matching (for work/school accounts)
   • If you’re in an Entra/Azure AD tenant, ask your admin to enable “number matching” in the Microsoft Authenticator policy.
   • You’ll have to type the exact number shown on screen to approve a request—accidental or malicious taps are thwarted.
6. Stay on Top of Your Security Settings
   • Regularly revisit https://account.microsoft.com/security to check recent activity.
   • Make sure you’ve enabled two-step verification and updated your recovery info (alternate email, phone).

Following these steps will secure your account and cut down on those pesky “Someone is trying to sign in” notifications. Hope this helps!
