About the JWT Encoder
The JWT encoder builds and signs a JSON Web Token from a header, a payload of claims, and a secret key, which is handy for testing APIs and authentication.
How to use it
- 1 Edit the payload claims, such as sub and exp.
- 2 Choose an algorithm and enter a secret.
- 3 Copy the signed token.
Frequently asked questions
Which algorithm should I use?
HS256 is the most common shared-secret algorithm. Use a long, random secret of at least 32 characters.
Should I put sensitive data in a JWT?
No. The payload is only encoded, not encrypted, so anyone holding the token can read it.
Should I use tokens made here in production?
Use this tool for testing. Production tokens should be created by your server, with secrets that never leave it.
