When off, only people who already have a Nexudus account with the same email can sign in. | | **Prevent users from using their Nexudus password to log in.** | Customers can only sign in to the members portal through SSO. | | **Prevent users from using their Nexudus password to log in to this dashboard.** | Admins can only sign in to the dashboard through SSO. | | **Sign in button label** | The text on the SSO button on your sign-in page, for example *Sign in with Microsoft*. | If you prevent Nexudus passwords **and** turn off creating new users, people without a Nexudus account can't get in at all. Test signing in as both a customer and an admin before turning off passwords. A person's email in Nexudus must match their email in the identity provider. ## Related * [Users and roles](/platform/settings/users-and-roles) — admin users * [Integrations](/integrations/overview) — all integrations This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
