About JWT
What is a JWT?
JSON Web Token (JWT) is a compact, URL-safe means of representing claims to be transferred between two parties.
Structure
A JWT consists of three parts: Header, Payload, and Signature, separated by dots (xxxxx.yyyyy.zzzzz).
Security Note
Never share your JWT secrets. This tool only decodes tokens client-side and doesn't verify signatures.
