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/
Microsoft authenticator
Good day. I’d like to ask how to solve a problem with Microsoft Authenticator. A Microsoft Authenticator suddenly appeared on my account out of nowhere, and I can’t remove it because I’ve lost access to the account. Logging in with a password doesn’t work, it can’t send an SMS to my phone, and the account is logged out everywhere. As far as I remember, I never set up Microsoft Authenticator.
Microsoft Authenticator issues
I’m simply locked out of my personal account because I lost access to my 2FA and the recovery form rejects due to active two-step verification. I’ve tried my verifying email and phone number but it rejects is due the active two step verification. I need manual identity verification or an escalation so my 2FA can be reset. Can you point me to the correct support channel for personal account recovery, because the link you sent is not working
Transfer Authenticator data from one iPhone to another
I bought a new iPhone. All the apps and settings that were present on my old iPhone are now on the new one but Microsoft Authenticator is empty. How can I transfer all my Authenticator accounts and passwords from the old iPhone to the new one, please?
Request for Manual 2FA Reset – Locked Out Despite Outlook App Access
I lost access to my Microsoft Authenticator because my old phone was factory-reset. Since then, I can’t sign in anywhere because I’m always asked for a 2FA code. Alternative verification methods (SMS/email) are also blocked due to too many attempts. The account recovery form is not available because 2FA was enabled, and the form gets automatically rejected. However, I am still signed in to the Outlook app on my old phone, but I cannot access any security settings or Microsoft account pages from within the app. This means I cannot change my 2FA options or disable two-step verification. I urgently need a manual reset of my 2FA or access to advanced identity verification, so I can prove ownership and regain access to my account.My hotmail account is blocked by Microsoft
My Hotmail account has been blocked by Microsoft due to “unusual activity,” and I urgently need help. I’ve attempted recovery multiple times, but the phone verification system is not working and all my requests keep getting rejected with the reason "that information I provided was not sufficient enough". I also have an active Microsoft 365 subscription tied to this email, and I can no longer access any of my Office 365 services. This issue needs immediate resolution.
Restore Authentication App do not work
Hi. I have had a problem with the Microsoft Authenticator and have deleted it from my Android Smartphone. Then I have installed it again and tried a recovery. But that is not working.

What I have tried: change WiFi to 5G deinstalled Authenticator App several times delete cache
Can't Login to Authenticator App
I am unable to login to my Microsoft 365 Business account, because I'm unable to login to my Authenticator App. I am also the only administrator on my business account, so no one in my organization can help me. Microsoft online support and phone support just keep sending me in circles. The only way I see to create a support ticket is to login, but my issue is that I can't login. Help, please!
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?
Conditional Access enforces MFA but Service Account still ask to secure account
Hi, I've setup Conditional Access policies to enforce MFA. But it excludes a group for service accounts. Whenever we login to a Service Account, they all ask to secure your account. Hit next > It says no MFA options are available > Skip. Both our own MFA conditional access policy and MS per-user conditional access policy excludes this group. The Legacy per-user authentication policy has all accounts disabled there in favour of the conditional access policy. We must be missing something here. Some of these are shared inboxes, others regular user accounts. Many of these services requires login through the typical Microsoft sign in screen to authorize access. Some does not support OpenID. So how do I 100% exclude service accounts from MFA? And how do I get rid of this popup to secure these accounts when it says no MFA options are available? TIA
