You may have misplaced a Wi-Fi password, but your laptop probably
remembers it if you’ve connected in the past. If not, you can always
grab the password from your router itself or reset the Wi-Fi passphrase
and set a new one.
These tricks allow you to recover the passphrase to any network
you’ve connected to in the past from your laptop. You can then easily
log into those networks from other devices or share the password with
your friends.
Recover the Password From a Laptop
If you’ve connected to the network in the past, the easiest way to do
this is to grab the password from a computer that’s connected to it.
Both Windows PCs and Macs make it easy to see your saved Wi-Fi
passphrases. You can’t easily find saved Wi-Fi passphrases on other
devices — doing this on Android will require root access,
and doing this on an iPhone or iPad will require jailbreaking. However,
if you’re using iCloud Keychain sync, Wi-Fi passwords from your iOS
device may sync to your Mac where you can access them.
To view a saved Wi-Fi password on Windows,
open the list of wireless networks in the Control Panel — you can
quickly do this by pressing Windows Key + R, typing ncpa.cpl into the
box, and pressing Enter. Right-click a saved Wi-Fi network, select
Status, and click the “Wireless Properties” button. Click over to the
Security tab and check the “Show characters” box to view the saved Wi-Fi
password. You must have administrator access to the computer to view
this information.
To recover a saved Wi-Fi password on a Mac,
open the “Keychain Access” app — press Command+Space, type Keychain
Access, and press Enter. Select the “Passwords” category and look for
the name of the Wi-Fi network. It will appear as an “AirPort network
password.” Either right-click the network name and select “Copy password
to clipboard” or right-click it, select “Get Info,” and check the “Show
password” box. You’ll have to enter your Mac’s username and password to
view this information — and it’ll only work if your account is an
administrator account.
Find it On Your Router
You can potentially view the Wi-Fi passphrase on your router, too.
Assuming you can’t connect to the router’s Wi-Fi, you can always
directly connect a laptop to your router via a wired Ethernet cable. Or,
if you already have a desktop PC connected to the router via an
Ethernet cable, that will do.
Find your router’s IP address and connect to its web interface.
Log in with your router’s administration password — if you’re like most
people, you never changed this from the default setting. You can find
the default username and password for your router online with a quick
web search, or look in its manual.
Go to the Wi-Fi section in your router’s web interface and look for
the Wi-Fi passphrase. You’ll find it here, and you can change it or just
write it down and use it to connect another device to.
If you haven’t changed your router’s Wi-Fi passphrase, you may also
find it printed on the router itself. Many modern routers — especially routers provided by your Internet service provider
— now come with random, unique passphrases. Look on your router for a
Wi-Fi passphrase printed on a sticker. It will only work if you’re still
using the default passphrase, of course.
Reset Your Router and Its Wi-Fi Password
if you’re locked out of your router — perhaps you can’t remember its administration password — you can always reset your router to its factory default settings.
You just need physical access to the router. All your router’s custom
settings will be wiped, so its Wi-Fi settings will be reset to the
default. Its administration password will also be set to the default, so
you can sign in and change the Wi-Fi passphrase to whatever you want.
Generally, you do this by locating a “Reset” button somewhere on the
router — it’s often a pinhole-sized button and you may need a bent
paperclip or similar small, narrow object to press it. You’ll usually
need to press the button down for ten seconds or so and your router will
reboot, wiping all its custom settings and restoring the default ones.
You can set it up from scratch, so it doesn’t matter if you don’t know
the Wi-Fi passphrase or anything else about the router.
Perform a web search for router-specific instructions or find your
router’s manual before doing this. You’ll find instructions that will
explain exactly how to reset your router and how to set it up from
scratch afterwards, complete with the password you’ll require to log
into the router.
If you’ve changed your own Wi-Fi network’s passphrase, you’ll need to
re-enter the new one on all your devices before you can connect again.
