If you buy a Supporter Pack on PC that includes an Early Access key, it will automatically be applied to the account used for the purchase. No extra steps are required—you can continue your adventure right where you left off.
Console players should ensure they purchase the Early Access Supporter Pack directly from the Xbox or PlayStation 5 store.
If you’re uncertain about your key status, you can check under https://www.pathofexile.com/my-account/early-access.
If you bought a key for one PC client (Standalone, Steam, or Epic) but want to play on another, you can claim a key for that platform at /my-account/early-access. These keys unlock the client in your library, but don’t grant Early Access by themselves.
For example, if you purchase a Supporter Pack through the Path of Exile website, you can claim a key to enable the game in your Steam Library.
