+## PasswordInput 密码输入框
+密码输入框组件通常与 [数字键盘](/zanui/vue/component/number-keyboard) 组件配合使用
+
+### 使用指南
+``` javascript
+import { PasswordInput, NumberKeyBoard } from 'vant';
+
+Vue.component(PasswordInput.name, PasswordInput);
+Vue.component(NumberKeyBoard.name, NumberKeyBoard);
+```
+
+### 代码演示
+
+#### 基础用法
+
+:::demo 基础用法
+```html
+<!-- 密码输入框 -->
+<van-password-input
+  :value="value"
+  info="密码为 6 位数字"
+  @focus="showKeyboard = true"
+></van-password-input>
+
+<!-- 数字键盘 -->
+<van-number-keyboard
+  :show="showKeyboard"
+  @input="onInput"
+  @delete="onDelete"
+  @blur="showKeyboard = false"
+></van-number-keyboard>
+```
