Hackers keep getting prompting me for a code on authenticator
hi Ketchupp You’re exactly right about what’s happening this is a known tactic called “MFA fatigue” or “push bombing.” Attackers already have your password (often from leaks) and keep trying to sign in, hoping you’ll accidentally approve a prompt in the Microsoft Authenticator.
The good news: they’re not getting in unless you approve it but you should still lock this down.
What you should do right away
Change your password (strong + unique)
- Make sure it’s not reused anywhere else
Enable “number matching” in Authenticator
- This is critical it forces you to enter a number shown on the login screen
- Prevents accidental approvals
Remove password sign-in (if possible)
- Turn on passwordless sign-in in your Microsoft account
- This blocks attackers who only have your password
- Strengthen your security
Check your sign-in activity
- Look for unfamiliar locations/devices
- Remove anything suspicious
Add another verification method
- Backup email or phone (in case you lose access)
Sign out of all sessions
Forces re-authentication everywhere
About blocking locations (your question)
Yes ,blocking unusual locations does help, but:
For work accounts, admins can enforce this via Microsoft Entra ID (Conditional Access policies)
For personal accounts, you don’t get full geo-blocking controls
So the best protection for personal use is:
Strong password
MFA with number matching
Passwordless sign-in
Important reminder
Never approve: Random prompts and Requests you didn’t initiate
If you keep getting them, it’s a signal your password is already exposed somewhere.
