Approve signups, create admin roles, and control access. Manage your app's users, control who can sign up, and configure role-based access to different parts of your app. ### How do I see my users? Go to the **Users & Access** tab in the sidebar. You can see every user who has signed up for your app, including their email, sign-up date, and status. You can also see more detail in the Users table of the **Database** tab.

### How do I control who can sign up? Click **Users & Access** → **Sign-in Rules** to limit sign-up to approved email addresses and domains. See [Sign-in Rules](/docs/apps/users-auth/sign-in-rules). ### How do I approve users before signing in? Ask Hercules to add a sign-up approval flow. Users will be able to create an account but won't be able to access your app until an admin approves them. ```text Add sign-up approval wrap theme={} Add a sign-up approval flow so new users need to be approved by an admin before they can access the app ``` ### How do I manage permissions and role-based access? Ask Hercules to set up role-based access control for your app. Describe the roles you need and what each role should be able to do. ```text Set up roles and permissions wrap theme={} Assign different roles to my users and let me customize the permissions for each. ``` ### How do I create admin and superadmin roles? Ask Hercules to implement role-based access controls with admin and superadmin roles. For B2B apps, give the admin role permission to access any organization rather than impersonating individual users. ```text Create admin roles wrap theme={} Implement role-based access controls with admin and superadmin roles ``` ### Can I impersonate a user? User impersonation is not currently available. We are building this feature soon. In the meantime, use role-based access controls and give admin users permissions to access organizations or projects rather than impersonate a specific user. ### Can I export or migrate my users? Yes, you can [export your database](/docs/apps/export-data). All of your users are available in the users table. If you host Convex on your own Convex database outside Hercules, you'll have to reconfigure your app's auth.
