Your Steam games, licences, downloadable content, Workshop subscriptions, and Steam Cloud saves belong to the Steam account that owns them. Make sure the correct account is linked before starting an Install & Play game.
Do I need to sign in every time?
No. After you connect and sign in to Steam, ONMO+ can use the linked account to verify game ownership without requiring a new Steam sign-in for every session.
Steam may occasionally ask you to sign in or complete Steam Guard verification again for security reasons.
Unlinking a Steam account
Open Settings in ONMO+.
Go to Account Info.
Open Linked Account.
Select Unlink next to Steam.
Switching to another Steam account
First unlink the current Steam account using the steps above. When you next launch an Install & Play game, sign in with the Steam account you want to use.
Steam content does not transfer between accounts. A game, licence, DLC, Workshop subscription, or Steam Cloud save will only be available when the Steam account associated with that content is linked and signed in.
