The Internet of Things is a storm that has been washing everyone download-stream since the beginning of the new millennium. Almost 96,7% users of Internet users connect their devices via Wi-Fi but the engineers have not been sleeping on duty when it comes to network security when it comes to Wi-Fi passwords. So how do you find your previous Wi-Fi password if have logged on the network before??

So you’re connected to a Wi-Fi network from way back when, but you can’t remember what the password is. Whether you’ve changed the default password or not, it’s simple to find it. You can look up any Wi-Fi network password if you’ve previously connected to that network from your computer or phone.
First: Check Your Router’s Default Password
If your router is still using the default username and password, it should be easy to find. Modern Wi-Fi routers–and the combined router/modem units offered by many Internet service providers–come with a default Wi-Fi network name and password. Each router has its own default password, which is often random.
To find the default password, find your Wi-Fi router and examine it. You should see a sticker somewhere on it that contains both the “SSID”–the wireless network name–and the password. If you haven’t changed the default password yet, you can use that password to connect to the router.
If you don’t see a default password printed on the router itself, try looking at the documentation that came with the router for more information.
What if you don’t have the manual or the password isn’t on the router sticker? As we mentioned in our guide to resetting your router’s password, you might be able to find the password by using common username and password combinations (e.g., “admin” for the username and “admin” for the password) or consulting RouterPasswords.com, a database of popular routers’ default logins.
Once you’ve connected to your router using the default password, make sure you change it and store the password in your password manager so your router is secure.
How to Find the Current Wi-Fi Network’s Password on Windows
If you’ve connected to a Wi-Fi network from a Windows laptop or desktop PC, Windows will remember that Wi-Fi network’s password. You can look up the Wi-Fi password on any Windows computer that’s currently connected to–or has previously connected to–that Wi-Fi network.
To look up the password for the Wi-Fi network you’re currently connected to on Windows, we’ll head to the Network and Sharing Center in the Control Panel. The quickest way to do this: Right-click on the Wireless Network icon in the taskbar and click “Open Network and Sharing Center.”
open network and sharing center
Click the name of the current Wi-Fi connection.
Click the “Wireless Properties” button in the Wi-Fi Status window that appears.
Click the “Security” tab and activate the “Show characters” checkbox to view the hidden password.
How to Find Passwords for Wi-Fi Networks You’ve Connected to Previously
Windows also stores the Wi-Fi password of networks you’ve connected to previously. In Windows 7 and earlier, you can find these from the Network and Sharing Center, but in Windows 8 and Windows 10, you’ll need to use the command prompt.
Find Passwords for Other Wi-Fi Networks in Windows 7 and Earlier
To get started, click the “Manage wireless networks” link in the left menu of the Network and Sharing Center.
You’ll see a list of the previous networks you’ve connected to. Double-click a network name to open the network’s properties.
In the network properties window, go to the Security tab and check the box next to “Show characters” to see the Wi-Fi password in the “Network security key” field.
Find Passwords for Other Wi-Fi Networks in Windows 8 and 10
In Windows 10 and 8.1, you’ll have to use the command prompt to find a previous network’s password. Right-click the Start button and select “Command Prompt” to quickly open it.
Then type in the following command:
netsh wlan show profiles
You’ll get a list of the Wi-Fi networks you’ve accessed before.
To find the password for one of the profiles, type in the following, replacing profilename with the name of the profile:
netsh wlan show profile name=profilename key=clear
Look for the “Key Content” line to find the Wi-Fi password for that Wi-Fi network.
How to Find the Password for Current or Previous Wi-Fi Networks on a Mac
If you have a Mac that’s currently connected to the Wi-Fi network or previously connected to it, you can also look up the password on that Mac.
To find the Wi-Fi password on your Mac, press Command+Space to open the Spotlight search dialog, type “Keychain Access” without the quotes, and press Enter to launch the Keychain Access app.
Locate the name of your Wi-Fi network in the list, click it, and then click the “info” button–it looks like an “i”–at the bottom of the window.
Click the “Show Password” checkbox in the window that appears. You’ll have to enter your username and password to gain access to the password. You’ll need an administrator account for this. Assuming your Mac account is an administrator account, just type your account’s username and password.
After you do, your Mac will show you the Wi-Fi network’s password.
How to Find a Wi-Fi Network’s Password on a Rooted Android Device
It’s not as easy to reveal the password for a Wi-Fi network on Android or iOS, but it is possible. Your Android device would need to be rooted, however.
First, download an alternative root-enabled file explorer, such as ES File Explorer. Launch the app and tap the menu button in the upper left-hand corner. Scroll down and slide the “Root Explorer” switch to “On”.
Grant it superuser access when prompted.
Then, in the left menu, go to Local > Device.
From there, browse to data/misc/wifi and open the wpa_supplicant.conf file in the file explorer’s text/HTML viewer.
Scroll down or search for the SSID to find the password for it, next to the term “psk”.
How to Find a Wi-Fi Network’s Password on a Jailbroken iPhone or iPad
The only way to reveal a Wi-Fi network’s password in iOS is to jailbreak your device first.
Open up the Cydia store and search for the WiFi Passwords tweak. Tap the Install button to install it. It’s compatible with iOS 6, 7, 8, and 9.
Once installed, open the app and you’ll be provided with a list of every Wi-Fi network you’ve connected to, along with their passwords. You can search for the network you’re looking for or scroll down to it.

Your wireless router has a variety of useful options you can configure. These are practically hidden — you wouldn’t know… [Read Article]
If you have access to the router’s web interface, you can also attempt to look it up there. This assumes that the router is either using its default username and password so you can log in, or that you know the current username and password for the router.
Go to your router’s web interface and sign in with the current username and password your router requires. Look through the router’s interface for a “Wi-Fi” or similarly labeled section. You’ll see the current Wi-Fi password displayed on this screen, and you can also choose to change it to anything you want from here.
