Enforce SAML SSO in Infisical

Enforcing SAML SSO ensures that members in your organization can only access Infisical by logging into the organization via Auth0.To enforce SAML SSO, you’re required to test out the SAML connection by successfully authenticating at least one Auth0 user with Infisical; Once you’ve completed this requirement, you can toggle the Enforce SAML SSO button to enforce SAML SSO.
In case of a lockout, an organization admin can use the Admin Login Portal in the /login/admin path e.g. https://app.infisical.com/login/admin.
If you are only using one organization on your Infisical instance, you can configure a default organization in the Server Admin Console to expedite SAML login.
If you’re configuring SAML SSO on a self-hosted instance of Infisical, make sure to set the AUTH_SECRET and SITE_URL environment variable for it to work:
  • AUTH_SECRET: A secret key used for signing and verifying JWT. This can be a random 32-byte base64 string generated with openssl rand -base64 32.
  • SITE_URL: The absolute URL of your self-hosted instance of Infisical including the protocol (e.g. https://app.infisical.com)
