LangSmith supports multiple authentication methods for easy sign-up and login.

​
Cloud

​
Email/Password

Users can use an email address and password to sign up and login to LangSmith.

​
Social Providers

Users can alternatively use their credentials from GitHub or Google.

​
SAML SSO

Enterprise customers can configure SAML SSO and SCIM

​
Self-Hosted

Self-hosted customers have more control over how their users can login to LangSmith. For more in-depth coverage of configuration options, see the self-hosting docs and Helm chart.

​
SSO with OAuth 2.0 and OIDC

Production installations should configure SSO in order to use an external identity provider. This enables users to login through an identity platform like Auth0/Okta. LangSmith supports almost any OIDC-compliant provider. Learn more about configuring SSO in the SSO configuration guide

​
Email/Password a.k.a. basic auth

This auth method requires very little configuration as it does not require an external identity provider. It is most appropriate to use for self-hosted trials. Learn more in the basic auth configuration guide

​
None

This authentication mode will be removed after the launch of Basic Auth.
If zero authentication methods are enabled, a self-hosted installation does not require any login/sign-up. This configuration should only be used for verifying installation at the infrastructure level, as the feature set supported in this mode is restricted with only a single organization and workspace.
