Open Jwt Decoder →❌ The Problem
JWT tokens are Base64 encoded - you can't read them directly.
✅ The Solution
Decode the token to see header, payload, and expiration time.
How to Do It
- Copy the JWT from your auth header
- Paste into the decoder
- View header (algorithm, type)
- View payload (claims, expiration)
💡 Pro Tips
- Check 'exp' claim for expiration time
- Never share tokens publicly
- This decodes but doesn't verify signatures
