How it works

Random bytes are encoded with URL-safe characters at the requested length; no identity, scope, or expiry claims are embedded. The token must be stored and checked by the server.

  • Long random values resist guessing.
  • URL-safe output avoids encoding changes in headers and links.

When to use this

Session cookies, API test credentials, and password-reset links use opaque tokens.

Edge cases

  • Tokens in URLs can leak through logs and referrers.
  • Short values are easier to guess online.
  • Generation alone adds no expiry, revocation, or user binding.
