Arknights Endfield Steam Account Linking allows existing players to keep their characters and progress when the Steam version launches on October 15, 2026. GRYPHLINE confirms that Steam shares its account data and servers with the other platforms. The important thing is choosing the existing-account option on your first Steam login, rather than registering a fresh account by mistake.
If you’ve been signing in through Google, Apple, Facebook or PlayStation, there’s one extra check worth making before launch. Your GRYPHLINE account needs a linked email to connect with Steam, and your character will only appear when you’re playing on the correct server. Here’s how to get both right.
Arknights Endfield Steam Account Linking: step-by-step
Install Endfield through Steam and open the game. At the first account screen, choose Log Into Existing Account & Link. Enter the credentials for the GRYPHLINE account where your current character is saved, then follow the prompts to finish linking it with Steam.
When you reach server selection, choose the server group your character already uses. GRYPHLINE separates Asia from Americas / Europe, and progress isn’t shared between them. Choosing the wrong one can make your account look empty even when your previous progress still exists elsewhere.
How to transfer your Arknights Endfield progress to Steam
There’s no save-file export, special transfer code or fresh game to start. The Steam client connects to the same account data as the original PC, mobile and PlayStation versions. Once the correct GRYPHLINE account is linked, you can continue on the server where you already created your character.
The publisher also says in-game purchases can be accessed on other supported platforms when you use the same GRYPHLINE account. If you played the earlier Steam Pioneer Test, GRYPHLINE confirmed that it had no data wipe, so its progress and purchases were retained too.
Arknights Endfield Steam Account Linking with Google and Apple
If you normally sign in through Google, Apple or Facebook, check whether that existing GRYPHLINE account already has an email attached. If it does, choose Log Into Existing Account & Link on Steam and enter the linked email.
If not, visit the GRYPHLINE Account Center and log in with your usual third-party account. Use the account settings to link an email address that hasn’t already been registered to another GRYPHLINE account. Then return to the Steam first-login screen, select the existing-account option and sign in with that email.
Don’t make a new GRYPHLINE account just to attach the email you want to use. You need to add it to the account that already holds your character. It’s worth checking that carefully now, before the Steam launch brings a flood of new players to the sign-in screen.
Arknights Endfield Steam Account Linking from PS5
PlayStation players can also carry their progress over. If your PSN-linked GRYPHLINE account already has an email, use it to link Steam. If it doesn’t, open Endfield on PlayStation and navigate to Settings → Platform & Account → User Center → Link Email.
Choose an email address that isn’t registered to a separate GRYPHLINE account, finish the linking steps and then use that email on Steam. GRYPHLINE’s account support specifically warns about creating a second account when linking PlayStation, so avoid guessing if you’re unsure which email your character uses.
Arknights Endfield Steam Account Linking release date
GRYPHLINE’s Steam announcement confirms October 15, 2026 as the launch date. Some Steam storefront displays show October 14 because of regional timing. Use your local Steam countdown alongside the publisher’s official date, rather than treating the two dates as different versions of the release.
Steam launches alongside Sanctuary of Ink. You don’t need to abandon the existing launcher if you prefer it; Steam is an additional way to access the same live game and account, provided the link and server are correct.
Arknights Endfield Steam Account Linking not working
If Steam opens an empty save, check the selected server before anything else. Your character may be on Americas / Europe while Steam is currently showing Asia, or the other way around. Next, check which email and GRYPHLINE account you linked. A newly registered account won’t contain your old progress.
If your login originally used Google, Apple, Facebook or PSN, make sure the linked email belongs to that same original account. Avoid creating more accounts while testing, because it can make the issue harder to untangle. If you’re still stuck, contact GRYPHLINE support through Settings → Platform & Account → Contact Customer Support or email endfield_cs@gryphline.com.
Arknights Endfield Steam Account Linking: can you change accounts?
The official Steam FAQ explains how to link Steam for the first time, but it doesn’t provide a general self-service method for switching a Steam login between different existing characters. Check the account and server before confirming, and ask support about any mistaken link instead of relying on unverified unlink instructions.
With Arknights Endfield Steam Account Linking, that first login is really the part worth getting right. Once Steam points to your original GRYPHLINE account, you should be able to carry on playing without rebuilding a character or losing your account’s existing progress.

The Arknights Endfield Steam Account Linking process should be straightforward if you’ve already connected an email to your GRYPHLINE account. Choose the existing-account option, enter the correct login and pick the server where your character lives. Once those details match, there’s no reason to start from scratch when the Steam client arrives.
