Bearer and POP tokens

As per MDN: Bearer Token: A security token with the property that any party in possession of the token (a bearer) can use the token in any way that any other party in possession of it can. Using a bearer token does not require a bearer to prove possession of cryptographic key material (proof-of-possession - POP). The Bearer Token or Refresh token is created for you by the Authentication server. When a user authenticates your application (client) the authentication server then goes and generates for your a Bearer Token (refresh token) which you can then use to get an Access Token. The Bearer Token is normally some kind of cryptic value created by the authentication server, it isn't random it is created based upon the user giving you access and the client your application getting access.

OpenID - by the OpenID Foundation

OpenID is a decentralised authentication protocol promoted by the non-profit OpenID Foundation. It allows users to be authenticated using a third-party service, eliminating the need for webmasters to provide their own ad hoc login systems. The original OpenID authentication protocol was developed in May 2005.

It was succeeded by OpenID Connect which is an identity layer on top of the IETF's OAuth 2.0 protocol.

OpenID Connect - OIDC

OpenID Connect is an identity layer on top of the OAuth 2.0 protocol. It introduced the Identity Token and the UserInfo Endpoint.

JWT - JSON Web Token - a claims set

In a nutshell

RFC 7519: JWTs represent a set of claims as a JSON object that is encoded in a JWS and/or JWE structure. This JSON object is the JWT Claims Set.

The member names within the JWT Claims Set are referred to as Claim Names. The corresponding values are referred to as Claim Values.

The overall structure is: A JWT may be enclosed in another JWE or JWS structure to create a Nested JWT, enabling nested signing and encryption to be performed.

JWTs are represented using the JWS Compact Serialization or the JWE CompactvSerialization.

Rationale

Before the JWT revolution, a token was just a string with no intrinsic meaning, e.g. 2pWS6RQmdZpE0TQ93X. That token was looked-up in a database, which held the claims for that token. This means that DB access (or cache) is required everytime the token is used.

JWTs encode and verify (via signing) their own claims. This allows to issue short-lived JWTs that are stateless (read: self-contained, don't depend on anybody else). They do not need to hit the DB. This reduces DB load and simplifies application architecture because only the service that issues the JWTs needs to worry about hitting the DB/persistence layer (the refresh_token).
