What is the primary account?
When a platform has more than one connected account, one of them is the primary. The primary is the account Claude uses by default when you don’t name a specific one. You can change it at any time, and you can still ask Claude to use any of the other accounts (see Using a specific account in Claude). A platform with a single connected account doesn’t need a primary — that account is always used.Add an account
Open the platform
Go to Workspace Settings → Integrations and click View on the connected platform’s card.
Click Add account
Click + Add account and authorize the other login (OAuth) or enter its credentials (API-key platforms). The new account is added alongside the existing ones — nothing is overwritten.

Set the primary account
Next to the account field is a star:- A filled star marks the current primary.
- An empty star means that account isn’t primary — click it to make it the primary.
Using a specific account in Claude
By default Claude uses the primary account. To work with another one, just ask — no setup required:You: Claude, show my connected Google Analytics accounts.
You: Pull last week’s spend for my other Google Ads account.Claude lists the connected accounts and uses the one you point to.
