# Token validation

You can configure application programming interface (API) *(tooltip: \<div class="paragraph">
\<p>A specification of interactions available for building software to access an application or service.\</p>
\</div>)* and Web + API applications to use access token validators to locally verify signed and encrypted access tokens. This feature works in conjunction with token providers that support JSON Web Signature (JWS) *(tooltip: \<div class="paragraph">
\<p>A signed instance of a JSON Web Token (JWT) based on IETF standard syntax and used for the exchange of signed content.\</p>
\</div>)* and JSON Web Encryption (JWE) *(tooltip: \<div class="paragraph">
\<p>A signed and encrypted instance of a JSON Web Token (JWT) based on IETF standard syntax and used for the exchange of encrypted content.\</p>
\</div>)* validation.
