<h2>RFC 7519: JSON Web Token</h2>

<p><a href="https://tools.ietf.org/html/rfc7519" class="rfc">tools.ietf.org/html/rfc7519</a></p>

<p>JSON Web Token (JWT, <a href="https://tools.ietf.org/html/rfc7519">RFC 7519</a>) is a way to encode claims in a JSON document that is then signed.</p>

<p>JWTs can be used as OAuth 2.0 <a href="/2/bearer-tokens/">Bearer Tokens</a> to encode all relevant parts of an access token into the access token itself instead of having to store them in a database.</p>
