To link your Stadia account to your Ubisoft account, you need to launch any of our games from the Stadia dashboard.
Once you launch the game:
Select Create account if you do not already have a Ubisoft account.
• Sign in to your Ubisoft account.
• The linking process will be completed once you have successfully logged in.
You can check if your accounts are linked in the Linked Accounts section at the bottom of the Account Information page.
Do not hesitate to contact us if you have any other questions.
