Signature
Signature verification isn't performed here — this tool only decodes the token locally. The signature segment can't be checked without the signing key/secret.
Decoding happens entirely in your browser — the token never leaves this page. This tool reads the header and
payload only; it does not verify the signature, since that needs the issuer's secret or public key. Don't
paste tokens from systems you don't trust into tools you don't trust.
