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.
