Frequently Asked Questions
Is it safe to paste JWT tokens into ToolPilot?
Yes! ToolPilot decodes the Base64Url segments entirely inside your browser. No tokens are logged, stored, or sent across any network.
Can this tool verify the cryptographic signature?
Signature verification requires your private/public secret key, which should never be pasted into any web utility. This tool inspects the visible payload claims safely.
