Arknights: Endfield Steam Account Linking Guide

Overview

Linking your Steam account to a Gryphline Account is the first hurdle every Endministrator faces when launching Arknights: Endfield on PC. The process is straightforward, but the correct path depends on whether you already have a Gryphline Account, previously used a third-party login, or are starting fresh. Choosing the wrong option can leave your existing progress stranded on another platform.

This guide walks through each scenario with testable steps, plus how to unlink later if you need to switch accounts. For more Arknights: Endfield news and guides, visit the game hub.

At a Glance

• Goal: Link your Steam account to a Gryphline Account to access the game.
• Prerequisites: A Steam account that owns or has access to Arknights: Endfield, and a Gryphline Account (existing or new).
• Estimated time: 5–10 minutes, depending on whether you need to add an email to a third-party account.
• Cost: Free. No currency or purchase required.
• Key rule: If you already have a game character on another platform, link your existing Gryphline Account to carry over progress.

Step-by-Step: Choose Your Account Situation

I Already Have a Gryphline Account

1. Launch the game through Steam and select [Log Into Existing Email Account & Link] on the account linking page.
2. Enter the email address of your existing Gryphline Account and request a verification code. Enter the code to proceed.
3. Confirm that your Steam account and Gryphline Account details are correct, then click [Confirm].

I Previously Used a Third-Party Login (Gmail, Apple, Facebook)

If your Gryphline Account already has an email address linked, use the [Log Into Existing Email Account & Link] option and sign in with that email.

If no email is linked, complete these steps first:

1. Go to the Gryphline Account Center and sign in using the third-party account you previously used.
2. Follow the on-screen instructions to link an email address. The email must not already be registered to a Gryphline Account.
3. Return to the game on Steam, select [Log Into Existing Email Account & Link], and sign in with the newly linked email to complete the process.

I Have Never Registered a Gryphline Account

1. Launch the game through Steam and select [Register & Link] on the account linking page.
2. Follow the on-screen instructions to create a Gryphline Account and link it to your Steam account.

How to Unlink Your Steam Account

You can unlink at any time using either method below.

Method One: In-Game

1. Enter the game and go to [Settings] → [Platform & Account].
2. Click [Go] on the right of the [Account Center].
3. Follow the on-screen instructions to complete the unlinking process.

Method Two: Gryphline Account Center

1. Visit the Gryphline Account Center and sign in to your linked Gryphline Account.
2. Follow the on-screen instructions to unlink your Steam account.

Troubleshooting

• Verification code not arriving: Check your spam folder and confirm the email address matches your Gryphline Account exactly. Not stated in official materials regarding resend limits.
• Email already registered: If you are trying to link an email that is already in use, you must use a different email address. The official instructions specify the email must not be already registered.
• Progress missing after linking: Ensure you selected the correct Gryphline Account. If you linked a new account by mistake, unlink and repeat the process with the correct credentials.
• Third-party login not recognized: Confirm you are signing into the Gryphline Account Center with the same third-party provider you used previously.
