As the title suggests, I keep having to enter my password every single time I open my games app. It usually prompts for this right after a restart. I've tried uninstalling, reinstalling, but it prompts to confirm my "identity" every time. This was recent, too, maybe coinciding with an update to the app... not sure, though. Any ideas? This is extremely frustrating to have to enter the password every single time.

This could be an issue with the Games app as it prompts you to enter the password every time. It can also be related the account which you are using to sign in to the computer.

Please assist me with the following information related to the issue:

1) Are you using a different account to login to the computer as compared to the Microsoft account while accessing apps and Windows Store?

2) Is this issue specific to Games app?

3) Did you make any changes to the Microsoft account settings related to the apps on the computer prior to this issue?

To login to the Windows Store or access the apps such as Games app, you can use the same Microsoft account which you use to login to the computer. If you are using a different Microsoft/local account, I would suggest you to login to the computer using the same account and then try accessing the Games app. Check if it resolves the issue. If the issue still persists, you can follow the methods to troubleshoot the issue further:
