clients using OAuth 2.0 access tokens. Using an access token obtained from an OAuth 2.0 authorization service (acts as a token issuer), you can identify a Pulsar client and associate it with a &quot;principal&quot; (or &quot;role&quot;) that is permitted to do some actions, such as publishing messages to a topic or consuming messages from a topic.</p><p>After communicating with the OAuth 2.0 server, the Pulsar client gets an access token from the server and passes this access token to brokers for authentication. By default, brokers can use the <code>org.apache.pulsar.broker.authentication.AuthenticationProviderToken</code>. Alternatively, you can customize the value of <code>AuthenticationProvider</code>.</p><h2 class="anchor anchorWithStickyNavbar_LWe7" id="enable-oauth2-authentication-on-brokersproxies">Enable OAuth2 authentication on brokers/proxies<a href="#enable-oauth2-authentication-on-brokersproxies" class="hash-link" aria-label="Direct link to Enable OAuth2 authentication on brokers/proxies" title="Direct link to Enable OAuth2 authentication on brokers/proxies"></a></h2><p>To configure brokers/proxies to authenticate clients using OAuth2, add the following parameters to the <code>conf/broker.conf</code> and the <code>conf/proxy.conf</code> file.
