What is the account used by flow when its runs. How to make sure that flow runs only via a specific account.
Each trigger or action in a Flow runs as the connection/account used for that trigger or action. By default, the connection used is the author of the Flow. You can add additional connections and use them for a selected trigger or action. Adding a connection implies that you have the user email and the password for the additional account.
@RKumar If your flow is running on an automated trigger then it will always run in the context of an owner of flow (Who created the flow).
You can still try "Manage Run-Only Users" but that only appears on manual triggers, such as Flow Button, SharePoint “For a selected item” and “For a selected file”.
