Frequently asked questions
What algorithms are supported?
▾
HS256, HS384, and HS512 (HMAC with SHA-2). These are symmetric algorithms — the same secret is used to both sign and verify the token.
What is the 'exp' claim?
▾
The expiration time claim. A Unix timestamp after which the token must not be accepted. Always set an expiration on tokens used for authentication.
Is it safe to generate tokens here?
▾
All signing runs in your browser using the Web Crypto API. Your secret never leaves your device. Still, treat generated tokens as development/testing tokens only.
