Hey everyone! I never usually post here, but I'm running into a frustrating issue with the Graph API and could really use some help. I have a script that elevates my permissions to User Administrator, which requires me to authenticate with MFA (Multi-Factor Authentication). The problem is that this process fails most of the time because running Disconnect-MgGraph doesn't seem to clear out the expired MFA token. So instead of being prompted for MFA when I should, it just uses the old token. I've tried manually running Disconnect-MgGraph and then Connect-MgGraph multiple times, but that only works randomly! I've scoured old issues on GitHub and various forums, but no one seems to have a concrete solution. I'm really hoping someone here has faced this and can point me in the right direction or suggest a workaround. I know some might say to just use the Azure GUI, but I really want to automate this process for efficiency in my job. Any insights would be greatly appreciated!

One option you could consider is setting up an app registration and using a service principal with a client secret or certificate for authentication. Are you using Entra as your main identity provider along with MS Auth for MFA? If you have ADFS in the background, make sure your MFA settings are correctly configured. Sometimes, it might even be a conditional access policy issue that's causing the hiccup. Also, clearing out the .mg folder in your user profile could help by removing the cached tokens, just a thought!
For my Connect commands, I always use '-UseDeviceAuthentication' or similar options. It lets me authenticate via a container in Firefox or a specific session in Chrome/Edge, and this method has worked wonders for me.
It's good to know I'm not the only one facing issues with Disconnect-MgGraph. Clearing the token cache could be a potential solution for you. You can try this command: Remove-Item "$env:USERPROFILE.mg" -Recurse -Force. Check out the second bullet point in the GitHub link provided for more on this!
I've personally never noticed this issue, but have you tried using the '-Scope Process' when connecting? This might prevent caching on the system level. Also, perhaps check if EasyPIM has addressed this problem.
This method seems to work better for clearing out old tokens. Keep an eye on it and let us know how it goes!
