+## How does APISIX configure ETCD with authentication?
+
+Suppose you have an ETCD cluster that enables the auth. To access this 
cluster, you need to configure the correct username and password for Apache 
APISIX in `conf/config.yaml`:
+
+```yaml
+deployment:
+  etcd:
+    host:
+      - "http://127.0.0.1:2379";
+    user: etcd_user             # username for etcd
+    password: etcd_password     # password for etcd
+```
+
+For other ETCD configurations, such as expiration times, retries, and so on, 
you can refer to the `ETCD` section in the `conf/config-default.yaml` file.

+## APISIX 如何配置带认证的 ETCD？
+
+假设您有一个启用身份验证的 ETCD 集群。要访问该集群，需要在 `conf/config.yaml` 中为 Apache APISIX 
配置正确的用户名和密码：
+
+```yaml
+deployment:
+  etcd:
+    host:
+      - "http://127.0.0.1:2379";
+    user: etcd_user             # username for etcd
+    password: etcd_password     # password for etcd
+```
+
+关于 ETCD 的其他配置，比如过期时间、重试次数等等，你可以参考 `conf/config-default.yaml` 文件中的 `ETCD` 部分。
