"sign-in frequency" every time not working as expected and described.
We have several PIM managed groups in an Entra ID tenant. Members are added as eligible. For the activation of the memberships an Authentication Context is created which is linked to a conditional access policy. The conditional access policy requires MFA with phishing resistant authentication factors, and "sign in frequency" is set to "every time". When activating membership authentication is required. When activating membership to another group (>5min in between activations) one would expect to request an authentication prompt, as described in Microsoft documentation. In Firefox this works as expected, In Edge and Chrome there is no re-authentication required every time, and sometimes even not for the first activation, not even in an in-private session. The device is not joined to this tenant, and the account used to log on is different from the one used to logon to the Entra ID portal. This is a test tenant with only those CA rules configured, no other policies or rules are in place. Anyone experiencing the same, or knowing the cause?
Disabling PIN-based login on Entra-joined PCs
Hi guys. Yesterday I took two machines off the domain and Entra joined them. The goal was 1) remove their access to domain resources 2) have tenant users login to the machine and get enriched tokens every time. this works as desired. The problem is every user gets prompted to set a pin. these are both shared secondary/tertiary PC's - there is no point to having a 6 digit PIN on them. I thought the new Authentication Methods tools had controls for this, but apparently not. A script was run to change certain related Reg Keys (by my onsite tech) but this had no change on reboot. textreg add "HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\PassportForWork" /v Enabled /t REG_DWORD /d 0 /freg add "HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\PassportForWork" /v DisablePostLogonProvisioning /t REG_DWORD /d 1 /f HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\PassportForWork Enabled key was set to 0, and DisablePostLogonProvisioning was set to 1. These are from various help threads I found here and other resources. Unfortunately, they do not work. Not sure what to do here. I've read there are InTune controls for this - but I don't really have the time to work out WindowsPC ennrollment profiles for 2 machines. The site has InTune, but only for iOS mobile management.

{ "error": "access_denied", "error_description": "AADSTS55203: Configuring multi-factor authentication method is blocked. Trace ID: Correlation ID: Timestamp: 2025-09-17 20:48:30Z", "error_codes": [ 55203 ], "timestamp": "2025-09-17 20:48:30Z", "trace_id": "", "correlation_id": "", "suberror": "provider_blocked_by_rep" } SMS authentication method was previously configured in our B2C Entra and was functioning correctly until last week, when it suddenly stopped working. Currently, users can only authenticate via email. Conditional Access policy is also in place that requires Multi-Factor Authentication (MFA).
Passwordless POC Blocked by CA BYOD Policy – Looking for Workarounds
We’re currently running a POC for passwordless authentication in our environment. One challenge we’ve hit is that our CA BYOD policy blocks personal devices, which prevents users from enabling passwordless sign-in via the Microsoft Authenticator app. Since Authenticator is not a cloud app, we can’t exclude it from the CA policy using the usual cloud app filters. This is causing issues when users try to register or use passwordless sign-in from their personal phones. Has anyone dealt with this scenario or found a workaround that allows passwordless sign-in while still enforcing BYOD restrictions? Any ideas, suggestions, or creative solutions would be much appreciated! Thanks in advance!
Entra External Authentication Method giving AADSTS900144 missing externalAuthenticationMethodId
Hi All, Has anyone else noticed in the last couple of days if EAM (External Authentication Method) is configured for MFA end users are getting: AADSTS900144: The request body must contain the following parameter: 'externalAuthenticationMethodId' Its been working for us fine for months/years but the last couple of days we are seeing heaps of the error above. I have raised a support case but zero response so far Regards, DanielConditional access, Persistant Browser sessions and Azure File shares in Storage Accounts
Hello, I am in the process of doing a POC for Azure file sync from DFS to Azure file shares with a end goal of using Azure files shares and getting rid of DFS. I want to use Entra for identity access. One of the changes I need to make is set Persistant browser session in our MFA all user policy to "Never" so that the storage enterprise app does not get targeted for MFA, otherwise it wont work. How do I go about doing this without effecting any other users as it's a global policy. I know I need to do this because I get this error when I add the Storage Account ent app to the targeted resources (formerly cloud apps) exclusion list; "Message from server: The server could not process the request because it is malformed or incorrect. 1032: ConditionalActionPolicy validation failed due to InvalidConditionsForPersistentBrowserSessionMode." Any ideas of how to get around this without affecting anyone else and only target the storage account ent app. Cheers
