The 'unity missing credentials' error typically occurs when Unity attempts to perform actions that require authentication, but cannot find the necessary credentials. For instance, this can happen if you are attempting to access Unity services (such as Unity Collaborate, Asset Store, or Cloud build) without being properly authenticated, or if your saved login information is incorrect or outdated. Another possible cause is the corruption of the Unity editor's cache, where such data might be stored.
Resolving this issue often involves two main steps: verifying your login details and clearing Unity's cache.
Verify Login Details: Make sure you're logged in with the correct account in the Unity application. Check the account used for accessing Unity Services and ensure it has the right permissions. If you're unsure, try logging out of your Unity account and signing back in.
Clear Unity's Cache: Some issues can be resolved by clearing the Unity Editor's cache. To do this:
%APPDATA%\..\LocalLow\Unity\. On Mac, go to
Afterward, relaunch Unity and enter your login credentials again.
If neither of these solutions work, it could suggest a problem with Unity's servers or an issue with your network settings preventing connection to Unity services. You may need to check Unity's server status, update your Unity software to the latest version, or troubleshoot your network configuration.
