Authentication is a crucial part of any application development. Whether you are developing an internal IT app for your employees – or building a portal for your partners – or exposing a set of APIs for developers building apps around your resources, Okta provides the right support for your projects.
The login experience is perhaps the single most important user experience any app developer needs to consider. To provide a seamless, attractive, yet secure authentication experience is not a trivial task. And typically, the login logic goes hand in hand with other features such as password reset and registration. More importantly, enhanced security in the form of strong and adaptive authentication during login is often critical to many implementations.
Okta provides many options for developers around the authentication experience. The foundation is built on top of the underlying feature set in Okta. Password policies, strong and adaptive authentication policies, password reset workflow, and more can all be configured easily in the administrator UI. Many of these policies can also be controlled through Okta’s API.
Okta provides the OAuth 2.0 and OpenID Connect implementations, the Authentication API, the Sign-in Widget, and the Auth JS SDK:
Okta allows you to control access to your application using both the OAuth 2.0 and OpenID Connect specifications. You can use Okta as your authorization server to retain all of your user information, and grant users tokens to control their authorization and authentication. Okta also supports using social login and pulling user’s external data into your Okta org.
To find out more about Okta’s OAuth 2.0 and OpenID Connect implementations, as well as social login, see the Authentication Guide.
The underlying foundation for the Sign-In Widget and Auth SDK is a comprehensive authentication REST API exposed through Okta. Use it as a standalone API to provide the identity layer on top of your existing application and authentication logic, or use it with the Okta Sessions API to obtain an Okta session cookie and access apps within Okta. This session integration provides an SSO experience across custom and Okta-managed apps.
For IT or ISVs who want to use Okta as an identity provider, Okta provides several options for secure SSO. SAML has been widely used as the single sign-on protocol by many ISVs and is supported by many identity management solutions. Okta provides comprehensive guidance for developers to implement a proper SAML service provider. For IT building internal apps and would like to support SSO, SAML is also a good option.
OpenID Connect is the emerging technology that provides an alternative implementation of SSO. Okta is a Certified OpenID Connect provider. Building on top of OAuth 2.0 framework, OpenID Connect is a modern implementation to support authentication and SSO. If you are an Okta customer, our OpenID Connect API is a great way to support SSO and is a simpler alternative to SAML.
For ISVs who want to provide SSO for their customers, both SAML and OpenID Connect are worth considering. Both protocols cover a wide variety of identity providers that you may encounter.
