Logging into Minecraft Feedback website automatically logs me out immediately

Hi, ExpensiveKoala! I'm sorry to hear you're having trouble signing in. No worries, I'm happy to assist you with this today.

Can you please try signing in your account at account.microsoft.com

Please let me know if you can login without issues.

Thank you!

Logging in there does work and immediately signs me into my profile, however moving to the Xbox home section automatically logs me out and makes it impossible to sign in.

I'm having a similar issue...

This seems to be a conflict between a feedback(zendesk?)-microsoft-account using the same email as my "real" microsoft account or something. They do not share the same password, but after following the zendesk instructions, it broke the password for my "real" account. And after fixing that, the feedback one is broken with this behavior again. It also successfully logs out my "real" microsoft account after logging out, despite me not being able to login to zendesk with the password for my "real" account.

I found a resolution that worked for me upon this happening to me in the last hour. Issue is not with the User's Microsoft Account, but with Zendesk Auth itself. I grabbed this URL https://minecraftfeedback.zendesk.com/auth/v2/login/ in order to force open the Sign In. Once there, goto 'New to Microsoft (Minecraft)? Sign Up at the bottom and click that, then put in your real name and email, as logging in with your password at this point will cause ZenDesk Auth to glitch in the same fashion.

This will send an email to your associated email account stating "An account already exists for Microsoft (Minecraft) using this email address. To access it, you can sign in or reset your password.

If you didn’t try to sign up for a new account, you can safely ignore this email."

Hit reset your password, put your current password in and you should be logged into Minecraft Feedback Website with your account, and you should be able to use your password again there if you log out (I tested and verified this myself).

So the issue isn't your account, it's Zendesk Auth, which Microsoft themselves need to fix.
