Frequently Asked Questions
What is a JWT token?
JWT (JSON Web Token) is a compact, URL-safe means of representing claims to be transferred between two parties. It is commonly used for authentication and information exchange.
Can you verify JWT signatures?
This tool decodes JWT tokens but does not verify signatures. Signature verification requires the secret key and should be done server-side.
