Not quite. I was referring specifically to the Admin access key which you set in the “My Foundry” page here :
This is the admin key to lock access to the main setup screen of Foundry where you can choose the world and install modules and systems.
If you’ve set an admin access key, then
you authenticated into Foundry with your admin access key,
then you logged out from the forge, created your daughter’s account, logged back in, then access the foundry setup page,
all within the same browser on the same computer, you would have still be logged into Foundry itself as admin. I’ve just tested that use case, and can confirm that it behaves that way (which is quite unfortunate).
That’s unrelated though to Player access keys which you set up in the Foundry world to give players access to the world.
No, she never should have seen the main Foundry setup page. I just tried it myself again to be extra sure, and this is the error that The Forge throws if you try to access the foundry setup page from a logged in Forge account that isn’t the owner (the one with the license and subscription), when there is no admin access key set :
And when an admin access key is set, then it’s delegated to Foundry itself which should show this :
From what you described, something doesn’t make sense to me though, you were in the world (as you said you had just created her player and went to “invitation links” within the world) so when she tried to access the game, it should have shown her the world join page, foundry would never display the setup page as long as a world is launched. You also said the first page she saw when she logged in after using the invitation link was the setup page, but The Forge wouldn’t have directed her to the game straight away but rather to the “presentation page” that you’ve configured, something like this : https://forge-vtt.com/game/demo for example in which you could then click “Launch Game” to actually access Foundry.
You then say she had to login again, which I assume is the Foundry join page where she selects her player and the access key you set.
So perhaps the confusion is that she said she was presented with a page that prompted her to “Launch game” and you thought it was the Foundry setup page rather than the game presentation page like this one ?
