随着时间的推移，几乎每个拥有笔记本电脑的人都可能连接到多个不同的无线网络。我经常出差，随身携带笔记本电脑，所以我的Mac上确实存储了一百多个无线网络。这很棒，因为只要我再次进入范围内，我就可以轻松连接到这些无线网络，即使是 6 个月后。

但是，有时我需要知道Wifi 网络^{(Wifi network)}的密码，通常是因为我必须将iPhone 或 iPad^{(iPhone or iPad)}等其他设备连接到网络。除了我自己的以外，我无法记住任何Wifi 网络^{(Wifi network)}的密码，所以我必须从其他地方获取它。如果您的计算机已经连接到网络，那么从那里找到密钥是非常有意义的。

幸运的是，在OS X^{(OS X)}中很容易做到这一点。所有密码、证书和其他安全信息^{(security information)}都存储在Keychain程序中。这是您保存的所有网站密码、网络设备连接等的存储位置。

^{(Find Stored WiFi Password)}使用钥匙串^(Keychain)查找存储的 WiFi 密码

首先，通过在Spotlight中搜索或转到Applications - Utilities打开^{(Applications – Utilities)}Keychain。

当钥匙串访问打开时，您将看到默认情况下在左侧^{(Keychain Access)}列^{(hand column)}中选中的登录项列表。此列表包括应用程序密码、Internet密码、网络密码和 Web 表单密码。

要查找无线网络的密码，您必须单击左上角菜单中的^{(left-hand menu)}系统^(System)。这些都应该归类为AirPort 网络密码^{(AirPort network password)}。

现在要查看实际密码，请继续并双击您选择的无线网络^{(wireless network)}。您将看到一个弹出窗口，其中列出了网络名称和其他一些详细信息。在底部，您会看到显示密码^{(Show password)} 复选框^{(check box)}。继续检查。

在你看到密码之前，你必须输入你的OS X 密码^{(OS X password)}，此时会弹出另一个对话框，说OS X 想要进行更改。输入管理员的名称和密码以允许此操作^{(OS X wants to make changes. Type an administrator’s name and password to allow this)}。

您必须再次输入OS X的^{(OS X)}用户名和密码^{(username and password)}。我不确定为什么它需要两次，但这就是它目前在小牛队的工作方式。完成此操作后，您最终将获得保存的Wifi 密码^{(Wifi password)}！

View Saved Wi-Fi (WPA, WEP) Passwords on OS X

Just about everybody who has a laptop has probably connected to several different wіrelеѕѕ networks ovеr the cоurse of time. I tend to travel a lot and take my laptop with me everywhere I go, so I literally have over a hundred wireless netwоrkѕ stored on my Mac. This is great because I can eaѕily connеct to those wireless networks whenever І’m in range again, even if іt’s 6 months later.

However, there are times when I need to know the password for the Wifi network, usually because I have to connect another device like my iPhone or iPad to the network. There is no way I ever remember that password any Wifi network other than my own, so I have to get it from somewhere else. If your computer is already connected to the network, it makes perfect sense to just find the key from there.

Luckily, it’s very easy to do this in OS X. All passwords, certificates and other security information is stored in the Keychain program. This is where all your saved passwords for websites, connections to network devices, etc are stored.

Find Stored WiFi Password using Keychain

First, open Keychain by either searching for it in Spotlight or going to Applications – Utilities.

When Keychain Access opens, you’ll see the list of login items by default selected in the left hand column. This list includes application passwords, Internet passwords, network passwords and web form passwords.

To find the passwords for wireless networks, you have to click on System in the top left-hand menu. These should all be categorized as AirPort network password.

Now to view the actual password, go ahead and double-click on the wireless network of your choice. You’ll get a pop up window that’ll list the name of the network and some other details. At the bottom, you’ll see the Show password check box. Go ahead and check that.

Before you get to see the password, you’ll have to type in your OS X password at which point another dialog will pop up saying OS X wants to make changes. Type an administrator’s name and password to allow this.

You’ll have to type in your username and password for OS X again. I’m not sure why it required twice, but that’s how it’s working on Mavericks at this point. Once you do this, you’ll finally get the saved Wifi password!
