如何查看电脑连接的wifi的密码

问题

很多时候我们电脑连上wifi之后就把密码忘记了，这个时候如果同事问自己密码是多少，如果作为程序员说不知道是不是感觉有点不好意思，哈哈……

解决

我使用的是windows电脑，就以windows为例说明下自己是如何查看的。

1. 打开windows命令行。按下windows + r快捷键，然后输入cmd回车就打开了
2. 命令行输入netsh wlan show profiles 可以看到电脑已经配置了wifi。效果如下

C:\Users\username>netsh wlan show profiles

Profiles on interface WLAN:

Group policy profiles (read only)
---------------------------------
    <None>

User profiles
-------------
    All User Profile     : test-5G

3. 然后输入netsh wlan show profiles name="profileName" key=clear就可以看到密码了。效果如下。Security settings中的Key Content后面的内容就是密码

C:\Users\username>netsh wlan show profiles name="test-5G" key=clear

Profile gc on interface WLAN:
=======================================================================

Applied: All User Profile
