Open Access Management (OpenAM) is an access management solution that includes Authentication, SSO, Authorization, Federation, Entitlements, and Web Services Security.

Cross Domain Single Sign On (CDSSO), SAML 2.0, OAuth 2.0 & OpenID Connect ensure that OpenAM integrates easily with legacy, custom, and cloud applications without requiring any modifications.
It's a developer-friendly, open-source control solution that allows you to own and protect your user's digital identities.

Key Features

Authentication Management

With OpenAM you can set up complex authentication processes using various authentication methods,
such as login and password, OTP, saved cookie, QR authentication, and more...
OpenAM also supports third-party identity providers using SAML, OAuth2, NTLM, and Kerberos protocols.

Access Management

Integrations with OpenIG or OpenAM Policy Agent allow you to set up flexible access policies to your resources.
There could be role-based, authentication level-based, or attribute-based and, if you need flexible logic, you can script access policy.

Cross Domain Single Sign-On

After a single authentication, a user gets access to all resources protected by OpenAM. So, there is no need to authenticate at other services.

Federation

OpenAM supports OAuth2/OIDC and SAMLv2 Federation protocols, so OpenAM can act as both Identity and Service Provider.

Extensibility

If you have to extend OpenAM functionality, it is relatively easy to do. OpenAM pluggable architecture allows modification relatively easy.
You can implement your custom authentication module, user data source, session data source, post-authentication process logic, and more...
