よくある質問
Is it safe to decode JWTs in the browser?
The header and payload are Base64-encoded (not encrypted), so they're always readable. The signature prevents tampering but doesn't hide content. Never put secrets in JWT payloads.
How do I debug 'token expired' errors?
Decode the token and check the 'exp' claim against the current time. Common causes: clock skew between servers, token not refreshed, or timezone issues.
