FAQ
- Does this verify the JWT signature?
- No. This tool only decodes the header and payload. Use a backend with the appropriate keys to verify signatures.
- Is it safe to paste production tokens?
- Avoid pasting sensitive or production tokens. While processing is local, treat tokens like passwords and rotate them if exposed.
