About JWT

JWT is the abbreviation of JSON Web Tokens. It is currently the most popular cross-domain authentication solution. It is an open standard (RFC 7519) for securely transmitting information between parties in JSON objects.

JWT contains authentication information, please keep it properly! This site does not record and store your JWT information, all verification and debugging are performed on the client side!

Payload is used to store the actual data to be transmitted. JWT specifies 7 official fields for optional use:
iss (Issuer): Issuer
sub (Subject): Subject
aud (Audience): Recipient
exp (Expiration time): Expiration time
nbf (Not Before): Effective time
iat (Issued At): Issued time
jti (JWT ID): Number
