Hi @Fabian Lewalder ,
I understand that you are having trouble logging into the Microsoft App Center and receiving the error, "Account with this email is already associated with another identity provider."
The error you are hitting is a known and documented issue. This issue started happening as of June 2021 when the App Center team implemented a tighter security policy for logins to the App Center portal. App Center binds each account only with a single identity provider. The association is created in the system during account registration and cannot be changed. If you used an identity provider such as GitHub, Facebook, or Google when you initially created your account, the system the system secured that authentication method (such as GitHub) as the only valid authentication method. Even if the same email address is used with a different Identity provider, the system rejects anything other than the original one.
We can’t tell from the error which ID you used, so you will have to try them one by one. To resolve this, I recommend trying these steps:
- Log in with each identity provider one by one
- Open a fresh incognito window each time or clear the browser cache before each login attempt.
If you wish to use a different associated identity provider, the only option is to close the original account and re-create it again since the system does not allow you to change the associated identity provider.
Let me know if this helps resolve the issue.
For documentation of this error and the troubleshooting steps, you can refer to Troubleshooting: Account is already associated with another identity provider
