Gamepass expiration lets you keep Minecraft using the Modrinth Launcher.

Please confirm the following.

• I checked the existing issues for duplicate problems
• I have tried resolving the issue using the support portal
• I have ensured my Modrinth App installation is up to date

What version of the Modrinth App are you using?

0.10.27

What operating systems are you seeing the problem on?

Windows

Describe the bug

If you obtain Minecraft via Gamepass and stay logged in when the Gamepass expires, then you will still be logged in and able to play without issue.
You can only play singleplayer in this state, however this is still a decently important bug to report as you can get the game with mods essentially for free this way.

Steps to reproduce

1. Purchase GamePass on a Microsoft Account that doesn't own Minecraft
2. Log into the Modrinth App with said account, and keep it logged in
3. Wait for GamePass to expire
4. Open Modrinth again

Expected behavior

When my Gamepass expired, I expected Modrinth to either automatically log out of the account, or not allow me to launch any instances, however it functions perfectly fine and allows me to swap accounts and launch instances without issue.

And this is a problem because?

[KloxEdgeX]

Because it gives unauthorized access to Minecraft to accounts that do not legally own the game, which opens up a lot of legal liability with Mojang.
Getting the game through Gamepass does not allow you to keep the game once it ends, the Modrinth Launcher does not seem to currently check the verification on if the Microsoft account owns Minecraft outside of the first login which leads to this exploit.

Gamepass trials that include Minecraft can usually be gotten for $1, which basically means that via this exploit people could get Minecraft basically for free.
