&lt;li&gt;&amp;ldquo;bearer&amp;rdquo; token grants access to the &amp;ldquo;bearer&amp;rdquo; of the token&lt;/li&gt;
&lt;li&gt;sender-constrained tokens to solve the problem of leaked &amp;ldquo;bearer&amp;rdquo; tokens&lt;/li&gt;
&lt;li&gt;client using a &amp;ldquo;bearer&amp;rdquo; token provides &amp;ldquo;a proof&amp;rdquo; every time it uses the token
&lt;ul&gt;
&lt;li&gt;&amp;ldquo;proof&amp;rdquo; ensures client has a secret private key&lt;/li&gt;
&lt;li&gt;&amp;ldquo;proof&amp;rdquo; is usually a JWT signed by the secret private key&lt;/li&gt;
&lt;li&gt;binds &amp;ldquo;proof&amp;rdquo; to a specific HTTP request&lt;/li&gt;
&lt;/ul&gt;
&lt;/li&gt;
&lt;li&gt;application layer&lt;/li&gt;
&lt;li&gt;no PKI required&lt;/li&gt;
