Azure AD users sign-ins keep repeatedly locked out
Dear Tech's, I'm facing issue that few users are keep getting locked out and sign-ins trying from different countries. How to prevent and what's the best way to suppress it. Advance thanks for your suggestions.
Best thing to do is disable basic authentication across the board and/or turn of legacy protocols such as POP/IMAP/SMTP, which are what usually "brute force" attempts use.
- amuru15Copper ContributorThank you! l will check if any legacy authentication.
