| iatIssued At - When the token was created | 1599996400 (9/13/2020, 11:26:40 AM (EXPIRED)) |
Signature
signature
⚠️ Signature verification requires the secret key. This tool only decodes the token.
💡 Tip: JWT tokens consist of three parts: Header (algorithm info), Payload (claims/data), and Signature (verification). This tool decodes the header and payload but cannot verify signatures without the secret key.
Code Examples
Here's how to achieve this in different programming languages:
1// Decode JWT (without verification)2const token = "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiJ1c...";3const [header, payload, signature] = token.split('.');4const decoded = {5 header: JSON.parse(atob(header)),6 payload: JSON.parse(atob(payload)),7 signature8};9console.log(decoded);1011// Using jwt-decode library12import jwt_decode from 'jwt-decode';13const decoded = jwt_decode(token);
