JWT Token Viewer
About JWT Tokens
- JWT tokens consist of three parts: header, payload, and signature
- The header typically contains the signing algorithm used
- The payload contains the claims (data)
- Common claims include: exp (expiration), iat (issued at), sub (subject)
- The signature is used to verify the token's authenticity
