Why can anyone read a JWT?

The header and payload of a JWT are only Base64URL-encoded, not encrypted, so never put passwords or secrets inside. Security comes from the server verifying the signature.

Frequently asked questions

Is my token sent anywhere?

No. Decoding happens entirely in your browser.

Does it verify the signature?

No. Verification needs the secret key; the tool only shows the contents.
