# Add a user to a Redox organization You can invite a user to join an existing organization in the Redox dashboard. [Learn more about Redox organizations and users](/basics/managing-access-for-your-redox-organization/what-are-redox-organizations-and-users). _We don’t currently support adding a user via API._ ## Prerequisites - A user must be assigned to an **organization owner** or **admin** role to manage users. [Learn more about user roles](/basics/managing-access-for-your-redox-organization/what-are-user-roles). ## Add a user in the Redox dashboard Follow these instructions if you don’t use SSO to log in to your Redox organization. 1. Log in to the dashboard. 2. Click **your username** at the bottom of the navigation menu. 3. From the user menu, select the **Access control** option**.** 4. The Access control page opens with three tabs. By default, a list of active organization users appears on the Users tab. Click the **Invite user** button. > **Not available for SSO organizations** > > Remember, this option isn’t available if your Redox organization is SSO-enabled. This is because SSO organizations must add users through their **identity provider** (**IdP**) first, not through the usual invitation process in the Redox dashboard. Refer to the SSO section for more details. ![The Invite user button appears at the top right of the Users tab.](https://images.ctfassets.net/cl3wt5ehhnlv/2tMxMcpNZXnitcN73E3jZc/c63253990ec8022a88ba7e1c137bb7b5/access-control-invite-user.png) *Click the Invite user button* 5.

All users that accept the invitation appear on the Users tab. > **Membership limit** > > One user can belong to multiple organizations. There’s a limit, though—which you probably won’t hit. You’ll run into an error if you try adding a user to more than 400 organizations. ## Add a user to an SSO organization For SSO-enabled organizations, you must complete steps in both your **identity provider** (**IdP**) and the Redox dashboard. Refer to your identity provider’s docs for managing users in their system. 1. Add a user in your IdP. 2. The user logs into the Redox dashboard. This triggers the membership sync from the IdP to Redox. 3. The user appears in the Redox organization. [Assign or change user role](/how-to-use-redox/manage-your-redox-setup/manage-user-roles).
