About WSO2 Identity Server

WSO2 Identity Server is an identity and access management solution that organizations can run on premises or in their own cloud environment. It is meant to secure applications for external consumers, an internal workforce, business customers and partners, and API access.

Standards support includes OAuth 2.0, OpenID Connect and SAML 2.0, with single sign-on, multi-factor and adaptive authentication. Recent versions add a visual designer for authentication flows, templates for configuring apps and login methods, simplified role-based access control for API policies, and a new authentication API for in-app login. AI-assisted features can generate flows from natural language descriptions and match branding. B2B capabilities include delegated administration and per-customer login options.

The code is Java and Apache-2.0 licensed. For teams that prefer not to operate it, WSO2 points to Asgardeo, a public identity cloud service built on the same technology core, which it says can be tried free of charge.
