Early Access key // SUB ACCOUNT

If I purchase an Early Access Key for Path of Exile 2 on Steam, can I only use it with the main account, or can I also use it with the subaccount on Steam?
Is it possible to use it on Xbox as well?

you need a separate key for each platform. eg: you cant use PC key on xbox

Not sure about the sub account question but keys you purchased on pc give only access for pc. If you want to play on pc AND Xbox for example you would need to get an additional EA key for xbox

Thank you so much for the quick responses!

I would like someone from the team to confirm if it’s possible to use subaccounts with the key on the same platform. I used to play on Xbox and made more purchases there than on PC. However, when linking the accounts, the PC account, which has fewer cosmetics and stash tabs, became the primary account.

This is why I want to know if the subaccount can also be used on PC if I purchase the Early Access key.

Additionally, with the Twitch reward (the hands that look like red wings), it was claimed only on the primary account. I would have liked it to be granted to both accounts since they are linked.

If your question is regarding the cosmetics you should know that while you play poe2 on Xbox you can only use the mtx which you purchased on Xbox, and same for pc where you can only use the mtx you purchased on pc.
You can login to the same account with your pc login info or at Xbox using your Xbox login but the Mtx are platform bound.
