+### Basic authentication
+
+You can require Basic authentication by leveraging the `security.basic` configuration:
+
+```yaml
+security:
+  basic:
+    username: "john.doe"
+    password-sha512: "6b97ed68d14eb3f1aa959ce5d49c7dc612e1eb1dafd73b1e705847483fd6a6c809f2ceb4e8df6ff9984c6298ff0285cace6614bf8daa9f0070101b6c89899e22"
+```
+
+The example above will require that you authenticate with the username `john.doe` as well as the password `hunter2`.
