One Gravity Login, Three Clients
SEA progress follows the Gravity account, not the Steam ID. Steam published July 26, 2026 and still requires the extra Gravity login because anti-cheat and mobile sync sit there. Gravity’s own FAQ: Steam Studio FAQ.
Link order that avoids throwaway characters:
- Create or confirm the Gravity email you used for pre-registration and mobile.
- Install mobile or standalone first if you already have a levelled character.
- On Steam, sign in with that same Gravity account — do not click “create new” because Steam is empty.
- Set the secondary password before you list a stall on any client.

What Does Not Transfer
- TW/HK/MO characters (January 15, 2026 launch) do not move onto SEA. Steam SEA is a new character if you only played Taiwan.
- Unlinked Steam-only profiles — wishlist mail can land on the first Steam character you make. Link before you claim.
- Codes are once per Gravity account, not once per client. Redeem on the main: How to Redeem.
Cross-play in the same party: Cross-Platform Play.
Where Linking Lives in the Client
Settings → Account → Platform Link (labels vary: Bind, Third-party, Steam). Bind once. Unlinking is often locked for months. If Steam overlay crashes during bind, finish the bind on mobile or standalone then return.
Mail, Pioneer, and Event tabs are account-wide on SEA when the bind is correct. If Pioneer mail is empty on Steam but present on mobile, you are on two Gravity logins — stop spending Star Stones until you fix it. Pioneer window: through September 16 — Pioneer Rewards.
Security After You Bind
Email recovery + secondary PIN + do not share the Gravity password in Discord. Phishing pages clone Gift Code Exchange. Codes only inside the client. Day 45 habits: Week Eight Guide.
