User-Based Explained
👨🏼💻 User-Based Login Explained
We’ve introduced a new user-based login system that lets you unlock desktop expansions from your iOS device. This system is separate from your GM Store account. You must create a new account here—using the same email as your GM Store account—but with a new password. Logging in with your GM Store credentials will not work.
If you already have a license key, you can continue using it as usual without logging in. The new login system is now mandatory as of July 1, 2025
- Follow all of the instructions for registering and resetting your password.
- Now, when you purchase any GM App Expansion, it will be unlocked for free on your iOS device by logging in.
Benefits
- One Unified Login – Now you only have to worry about one login that will work for all of your apps, instead of separate licenses for each app.
- iOS and Desktop Communication – You will now be able to unlock your expansions on your iOS device using the same login and password.
- Offline Options Available – Don't worry, we still have offline options available as well, but initial internet is still required.
