What is JWT?
JWT, or JSON Web Token, is a compact, URL-safe means of representing claims to be transferred between two parties. These claims are often used for authentication and authorization purposes. A JWT is a string with encoded information, split into three parts: header, payload, and signature.
Decoding a JWT allows you to inspect its contents — useful when you want to understand the information it carries or troubleshoot authentication issues. The decoded JWT reveals the claims made by the token.
Practical Flow
How to Use This Tool
- 1Paste JWT: Copy and paste your JWT into the left text box.
- 2Understanding the Result: The decoded JWT will be displayed, showing the header and payload details.
- 3Edit Payload: Modify the payload as needed. Update user details, expiration times, or any relevant claims.
Reference
Example
- Header: { "alg": "HS256", "typ": "JWT" }
- Payload: { "user_id": 123, "username": "john_doe", "exp": 1672531200 }
Keep In Mind
Important Note
Be cautious when sharing or using decoded JWT information. Sensitive details like user identifiers may be exposed.
