About JWT Tokens

JWT (JSON Web Token) is a compact, URL-safe means of representing claims to be transferred between two parties.

  • JWT tokens consist of three parts: Header, Payload, and Signature, separated by dots (.)
  • The Header contains metadata about the token (algorithm, type)
  • The Payload contains the claims (data) encoded as JSON
