Microsoft to block unauthorized scripts in Entra ID logins with 2026 CSP update
18 décembre 2025 à 12:45
Microsoft is enforcing stricter Content Security Policy (CSP) for Entra ID authentication, blocking unauthorized scripts from executing during sign-in. Organizations using browser extensions or third-party tools that inject scripts into login.microsoftonline.com must identify and replace these tools before enforcement, as they will stop functioning while users can still sign in successfully.
