JWT Decoder
1. What is a JWT Decoder?
A JWT Decoder is a tool that helps you read and understand JSON Web Tokens (JWTs). It breaks down the token into its parts—the header, payload, and signature—so you can see the data inside.
2. Why do I need to decode a JWT?
Decoding a JWT lets you verify the information it contains. This helps you check if the token is valid and see user claims, expiration dates, and other details to ensure secure user authentication.
3. How do I use the JWT Decoder?
Just paste your JWT into the decoder tool and hit the decode button. You’ll instantly see the decoded information, including the header, payload, and signature.
4. Can I decode a JWT manually?
Yes, you can decode a JWT manually using base64 decoding, but using a JWT Decoder tool is much quicker and easier.
5. What if my JWT doesn’t decode?
If your JWT doesn’t decode, it might be malformed. Double-check the token format or ensure it’s a valid JWT.
7. Can I trust the information in a decoded JWT?
Always validate the token with the server that issued it. Decoding alone does not confirm its authenticity.
