# Testing OAuth with MXCU
Use the MXCU (OAuth) test institution (institution code: `mxcu_oauth`) to test OAuth flows in the integration environment.
**INFO**
In the integration environment, a `user` can only have one OAuth `member`.
1. Select **MXCU (OAuth)** from search, or load the Connect Widget via `current_institution_code: "mxcu_oauth"`. You'll see the following screen before redirecting to the OAuth provider.
2. Sign in at the test OAuth provider using these credentials:
* Username: `mxtest`
* Password: `testpassword`
3. That will take you to the authorization page. From here, you can choose which accounts to authorize:
* Select **Authorize** to simulate a successful authorization.
* Select **Deny** to simulate an error or denied authorization.
**WARNING**
While the MXCU (OAuth) test institution lets you choose which accounts to authorize, this behavior can vary between real institutions.
