JWT Decoder
Decode and verify JSON Web Tokens (JWT) to inspect their contents
About JWT Tokens
JSON Web Tokens (JWT) are an open, industry standard RFC 7519 method for representing claims securely between two parties. JWTs are commonly used for authentication and information exchange in web applications.
A JWT consists of three parts separated by dots (.):
- Header - Contains the token type and the signing algorithm being used
- Payload - Contains the claims (statements about an entity) and additional data
- Signature - Used to verify that the sender of the JWT is who it says it is
Note: This tool only decodes JWTs. It does not verify signatures as that would require the secret key. The expiration status is based on the token's exp claim if present.
