JSON Web Token vs Keycloak: What are the differences?

JSON Web Token: A JSON-based open standard for creating access tokens. JSON Web Token is an open standard that defines a compact and self-contained way for securely transmitting information between parties as a JSON object. This information can be verified and trusted because it is digitally signed; Keycloak: An open source identity and access management solution. It is an Open Source Identity and Access Management For Modern Applications and Services. It adds authentication to applications and secure services with minimum fuss. No need to deal with storing users or authenticating users. It's all available out of the box.

JSON Web Token and Keycloak belong to "User Management and Authentication" category of the tech stack.

JSON Web Token is an open source tool with 2.59K GitHub stars and 259 GitHub forks. Here's a link to JSON Web Token's open source repository on GitHub.

I am working on building a platform in my company that will provide a single sign on to all of the internal products to the customer. To do that we need to build an Authorisation server to comply with the OIDC protocol. Earlier we had built the Auth server using the Spring Security OAuth project but since in Spring Security 5.x it is no longer supported we are planning to get over with it as well. Below are the 2 options that I was considering to replace the Spring Auth Server. 1. Keycloak 2. Okta 3. Auth0 Please advise which one to use.

Keycloak

It isn't clear if beside the AuthZ requirement you had others, but given the scenario you described my suggestion would for you to go with Keycloak. First of all because you have already an onpremise IdP and with Keycloak you could maintain that setup (if privacy is a concern). Another important point is configuration and customization: I would assume with Spring OAuth you might have had some custom logic around authentication, this can be easily reconfigured in Keycloak by leveraging SPI (https://www.keycloak.org/docs/latest/server_development/index.html#_auth_spi). Finally AuthZ as a functionality is well developed, based on standard protocols and extensible on Keycloak (https://www.keycloak.org/docs/latest/authorization_services/)

Keycloak

We have good experience using Keycloak for SSO with OIDC with our Spring Boot based applications. It's free, easy to install and configure, extensible - so I recommend it.
