+
+[Basic authentication](https://en.wikipedia.org/wiki/Basic_access_authentication) is a simple authentication scheme built into the HTTP protocol, which uses base64-encoded username and password pairs as credentials.
+
+## Prerequisites
+
+Install [`htpasswd`](https://httpd.apache.org/docs/2.4/programs/htpasswd.html) in your environment to create a password file for storing username-password pairs.
+
+* For Ubuntu/Debian, run the following command to install `htpasswd`.
+   
+   ```
+   apt install apache2-utils
+   ```
+ 
+* For CentOS/RHEL, run the following command to install `htpasswd`.
+
+   ```
+   yum install httpd-tools
+   ```
+
+## Create your authentication file
+
+:::note
+Currently, you can use MD5 (recommended) and CRYPT encryption to authenticate your password.
+:::
+
+Create a password file named `.htpasswd` with a user account `superuser/admin`:
+* Use MD5 encryption (recommended):
+
+   ```
+   htpasswd -cmb .htpasswd superuser admin
+   ```
+
+* Use CRYPT encryption:
+
+   ```
+   htpasswd -cdb .htpasswd superuser admin
+   ```
+
+You can preview the content of your password file by running the following command:
+
+```
+cat .htpasswd
+superuser:$apr1$GBIYZYFZ$MzLcPrvoUky16mLcK6UtX/
+```
+
+## Enable basic authentication on brokers
+
+To configure brokers to authenticate clients, complete the following steps.
+
+1. Add the following parameters to the `conf/broker.conf` file. If you use a standalone Pulsar, you need to add these parameters to the `conf/standalone.conf` file.
+
+   ```
+   # Configuration to enable Basic authentication
+   authenticationEnabled=true
+   authenticationProviders=org.apache.pulsar.broker.authentication.AuthenticationProviderBasic
+
+   # Authentication settings of the broker itself. Used when the broker connects to other brokers, either in same or other clusters
+   brokerClientAuthenticationPlugin=org.apache.pulsar.client.impl.auth.AuthenticationBasic
+   brokerClientAuthenticationParameters={"userId":"superuser","password":"admin"}
+
+   # If this flag is set then the broker authenticates the original Auth data
+   # else it just accepts the originalPrincipal and authorizes it (if required).
+   authenticateOriginalAuthData=true
+   ```
+
+2. Set an environment variable named `pulsar.auth.basic.conf` and the value is `.htpasswd`. Pulsar reads this environment variable to implement HTTP basic authentication.
+
+## Enable basic authentication on proxies
+
+To configure proxies to authenticate clients, complete the following steps.
+
+1. Add the following parameters to the `conf/proxy.conf` file:
+
+   ```
+   # For clients connecting to the proxy
+   authenticationEnabled=true
+   authenticationProviders=org.apache.pulsar.broker.authentication.AuthenticationProviderBasic
+
+   # For the proxy to connect to brokers
+   brokerClientAuthenticationPlugin=org.apache.pulsar.client.impl.auth.AuthenticationBasic
+   brokerClientAuthenticationParameters={"userId":"superuser","password":"admin"}
+
+   # Whether client authorization credentials are forwarded to the broker for re-authorization.
+   # Authentication must be enabled via authenticationEnabled=true for this to take effect.
+   forwardAuthorizationCredentials=true
+   ```
+
+2. Set an environment variable named `pulsar.auth.basic.conf` and the value is `.htpasswd`. Pulsar reads this environment variable to implement HTTP basic authentication.
+
+## Configure basic authentication through CLI tools
