}Signature
signature-not-validated
This tool only decodes the token structure. It does not verify the signature or confirm the token is trustworthy.
The tool reads the JWT header and payload with Base64URL decoding so you can inspect claims such as alg, iss, sub, aud, iat, nbf, and exp quickly.
No. It helps you inspect the structure, but trust and authenticity require signature verification elsewhere.
Yes. If the segments are valid Base64URL, the header and payload can be decoded for inspection without verifying the signature.
