Android Teams login fails during ADFS federation with SSL error
Hello Android mobile users cannot sign in to Microsoft Teams The login fails during the ADFS federation step due to an SSL error Environment Android OS versions 10 to 14 Microsoft Teams mobile app Entra ID federated with on premises ADFS ADFS service URL is masked Public certificate issued by Sectigo Issue description After entering the account in Teams the sign in process redirects to ADFS The page does not load correctly and shows infinite loading or a blank screen The same account works normally on PC browser PC Teams and Outlook Web The issue occurs only on Android mobile apps that use WebView Android log summary OAuth2 WebView client received SSL error Primary error SSL untrusted Wildcard certificate for masked domain Certificate issued by Sectigo Public Server Authentication CA Troubleshooting performed Device date and time verified Teams app cache cleared and app reinstalled Issue reproduced on multiple Android versions and devices PC authentication works with the same certificate Questions Can Android WebView or Microsoft mobile authentication fail with SSL untrusted when the ADFS server does not provide a complete certificate chain Is full chain certificate configuration required on ADFS IIS for mobile authentication Can SSL inspection or proxy interception cause this issue only on Android apps while PC browsers work normally Are there official Microsoft recommendations for certificate configuration when using ADFS federation with Android mobile apps Additional information The same behavior occurs in other Microsoft mobile apps The suspected causes are incomplete certificate chain or network SSL inspection Thank you
Graph http 449 throttled
We are experiencing a lot of Microsoft Graph trolling errors from some of our applications that are hosted in Azure Web App Services and other third party such as Front App to name one. I am trying to find an approach or strategy to figure out and narrow down what may be causing so many of these events. Whether I can narrow down by application or process, I am not sure yet. We enforce MFA on all our users, but of course, on Azure Enterprise Applications, we don't, which are used extensively in our ecosystem of apps. Any help is much appreciated here.
Microsoft Authenticator Passkeys for Entra ID on unmanaged devices
Hello, has anyone successfully registered passkeys on an unmanaged phone in an organisation with device compliance policies? Use case is to provide a phishing-resistant MFA option via Authenticator app for logging into apps on their desktop. Users already have authenticator app on their phone and do number matching MFA. https://learn.microsoft.com/en-us/entra/identity/authentication/how-to-register-passkey-authenticator?tabs=iOS When I select "Create a passkey" - I need to log into my account. However I'm blocked from successful authentication because I have conditional access policies to require compliant devices. As my mobile phone is not enrolled into Intune, I never get to the step where the passkey is created and registered. Based on the constraints - it seems like passkeys cannot be used for unmanaged/BYOD devices for organisations that have device compliance policies. It can only be used for users who have enrolled their mobile phone. Looking to see if anyone has tips or different experience using passkeys on unmanaged mobile phones to log into Entra?Journey to Passwordless Authentication Might Include Some Bumps
Microsoft recommends passwordless authentication to help secure Microsoft 365 tenants. The latest is synced passkeys, something that apparently leads to “syncability,” whatever that might mean. In any case, after some struggles, I managed to enable synched passkeys for my iPhone and then started to consider how to remediate user accounts that are flagged with a high-risk (compromised) status when they can’t simply update their password. https://office365itpros.com/2025/12/04/passwordless-authentication/
Nested App Authentication (NAA) token to protect middle-tier server
I'm working on an outlook addin and want to use the NAA accesstoken to validate the user on an api running on a php webserver. The addin runs as a taskepane (created with yo office) with the app only manifest. I have setup NAA to do Microsoft graph calls on behalf of the user. I have used this guid to setup NAA (copy/past) https://learn.microsoft.com/en-us/office/dev/add-ins/develop/enable-nested-app-authentication-in-your-add-in I have setup a php server (not in Microsoft infrastruktur) for a simple API, that handlers MySQL calls and app only calls to Microsoft graph. The php api authenticate itself with a client secret from the Azure app registration. Both are working as expected. Can i use the accesstoken from the NAA, to authenticate the user on the php server? If it can be done how do I validate the token?Azure AD Health Failing
I am on the latest version of Azure AD Connect (2.5.79.0)... There are no network/DNS/connectivity issues at our site, it seems to me that Azure AD Health Service is having trouble because the endpoint is experiencing a service issue.. Is anyone else having the same problem with failure alerts/etc? I checked by running "Test-MicrosoftEntraConnectHealthConnectivity -Role SYNC" command, the stack trace throws an undocumented error number and complains of rate limiting issues... smells like the server is being overwhelmed or there are other issues slowing down the endpoint/service with the consequence that connections are piling up causing this error: Connectivity Test Step 1 of 2: Testing dependent service endpoints begins ...

Component https://myaccount.microsoft.com Run command: ms-settings:yourinfo Environment Profile picture uploaded through https://myaccount.microsoft.com Profile picture uploaded through Run command (WIN+R): ms-settings:yourinfo Retrieved via Microsoft Graph SDK / Graph REST API endpoint /v1.0/me/photos/$value Steps to Reproduce Go to https://myaccount.microsoft.com. Upload a new profile picture (no presence, badge, or branding requested). Retrieve the profile picture using Microsoft Graph endpoint: GET https://graph.microsoft.com/v1.0/me/photos/$value Render the image in the client application. Expected Result The raw profile photo is shown exactly as stored—no overlays, rings, badges, or branding. Actual Result The component renders an overlay (e.g., presence badge/ring/branding) on top of the photo, altering the image. Impact Users see altered profile photos, leading to inconsistencies with expectations. Breaks brand/UX design guidelines that rely on unmodified profile images. Severity Medium–High (affects identity consistency across apps using Graph). Notes This happens even though no overlay option was requested in either the upload or retrieval flow. Alternative: Steps to Reproduce and working as expected Run command (WIN+R): ms-settings:yourinfo Upload a new profile picture (no presence, badge, or branding requested). Retrieve the profile picture using Microsoft Graph endpoint: GET https://graph.microsoft.com/v1.0/me/photos/$value Render the image in the client application. Expected Result The raw profile photo is shown exactly as stored—no overlays, rings, badges, or branding. Actual Result The raw profile photo is shown exactly as stored—no overlays, rings, badges, or branding.My Azure login is stuck at MFA and cannot proceed
In August, I was still able to log in to Azure, and by logging in through GitHub I could bypass 2FA. But now, no matter how I try, logging in via GitHub always requires 2FA. I can’t access my Azure account anymore—nothing works. The system prompts me to use Microsoft Authenticator to confirm a two-digit code in real time. My Microsoft Authenticator on my iPhone is logged into the same Microsoft account, but I’m not receiving any verification requests for Azure login. No matter how much I refresh, nothing shows up. I’ve already updated the Microsoft Authenticator app to the latest version from the App Store. However, my personal Microsoft account works fine and can log in without any issues.TAP Question
Hi All I hope you are well. Anyway, I'm looking for some clarification over Temporary Access Passes (TAP) as our testing seems to reveal some different results from those listed in the MS documentation. Here's the scenario's. My understanding: Require MFA policy deployed via Conditional Access New user F3 user starts Issue TAP to user where they can then setup MFA themselves via My Security Info etc Testing results: Require MFA policy deployed via Conditional Access New user F3 user starts User can setup MFA themselves via MS Auth app on a mobile device or via My Security Info in a browser MS TAP Info page: "The most common use for a TAP is for a user to register authentication details during the first sign-in or device setup, without the need to complete extra security prompts." Ref: Configure a Temporary Access Pass in Microsoft Entra ID to register passwordless authentication methods - Microsoft Entra ID | Microsoft Learn Have I missed understood something here and if a new user can indeed still setup MFA is there any real need for a TAP for first time user? Info appreciated. SK
Token replay question
I had a case of a user being phished and their token being used in a replay attack. The replay appeared in the sign in logs from a different IP address to the "true" users IP. I then saw activity on the account originating from the original IP until we killed the session a few hours later. I had someone suggest that in a token replay the M365 audit\activity logs and Entra ID signing logs will show the original persons IP, not the attackers. Can anyone confirm this?
