# Authentication methods
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](/administration/how_to_guides/organization_management/set_up_saml_sso.mdx) and [SCIM](/administration/how_to_guides/organization_management/set_up_scim.mdx)
## 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](../../self_hosting)
and [Helm chart](https://github.com/langchain-ai/helm/tree/main/charts/langsmith).
### 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](../../self_hosting/configuration/sso)
### Email/Password a.k.a. basic auth {#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](../../self_hosting/configuration/basic_auth)
### None
:::warning
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.
