Token Info

What is a JWT?

A JSON Web Token (JWT) is a compact, URL-safe token format used for securely transmitting information between parties. It consists of three parts separated by dots (.):

  1. Header - algorithm and token type (e.g. HS256, RS256)
  2. Payload - claims/data (e.g. sub, iat, exp)
  3. Signature - verifies the token hasn't been tampered with

Note: This tool only decodes the token. It does not verify the signature.
