How to Link Arknights: Endfield PSN and Gryphline Accounts
Link the PSN and Gryphline accounts before the first PlayStation 5 login creates the wrong save. The correct route depends on whether progress already exists on PC or mobile, or began on PS5.
Match the PSN region and account state
GRYPHLINE syncs progress only within the same server. The PS5 server is assigned from the PSN account region and cannot be selected manually, so confirm that it matches the Americas / Europe or Asia server used by the existing Gryphline progress.
For existing iOS, Android or PC progress, use a PSN account that has never logged into Arknights: Endfield. The existing Gryphline Account can be linked only from the first-login prompt on that fresh PSN account.
A PSN account with existing PlayStation progress follows a different route: Settings > Platform & Account > User Center > Link Email, using an email address that has never been registered as a Gryphline Account.
Link existing progress on the first login
The numbered route preserves an existing Gryphline save from PC or mobile. For progress that began on PS5, use Settings > Platform & Account > User Center > Link Email and bind a previously unregistered email instead.
One save works across the same server
GRYPHLINE states that the linked PSN and Gryphline accounts share the same progress on PS5, PC, iOS and Android when every login uses the same server.
Login methods remain platform-specific: use the Gryphline Account on PC or mobile and the linked PSN account on PlayStation 5. Existing achievement progress unlocks the corresponding PlayStation trophies after the linked save logs in on PS5.
The first PS5 login decides the link
The linking prompt for an existing Gryphline Account appears only during the PSN account’s first login after accepting the user agreement. Selecting Quick Login skips the link and automatically creates a new Gryphline Account for that PSN account.
One PSN account can link to one Gryphline Account, and one registered Gryphline email can bind to one PSN account. Different servers do not share progress.
GRYPHLINE permits account unlinking through the Gryphline Account User Center, but each account can use the unlink action only once.
Recover from skipped or failed linking
The game closed before linking completed: GRYPHLINE states that the linking pop-up appears again on the next login when the first-login process ended abnormally.
The prompt was skipped with Quick Login: that PSN account now owns a newly created Gryphline Account and cannot link to an already registered Gryphline email. Use a fresh PSN account for the existing Gryphline progress.
An existing PS5 save rejects the email: use an email address that has never been registered as a Gryphline Account, then link it through Settings > Platform & Account > User Center > Link Email.
The wrong server appears on PS5: the server follows the PSN account region and cannot be changed manually. Use a PSN region that maps to the server holding the intended progress.
