WiFi (Wireless) Password Security - WEP, WPA, WPA2, WPA3, WPS Explained

This is an animated video explaining wireless password security options. It explains WEP, WPA, WPA2, WPA3, WPS, and Access Control. It also explains AES and TKIP.

I like how you can’t choose WEP as a security protocol, but you’re allowed to choose “NONE”. The router is like “you can choose no security but you can’t choose bad security”

Totally loving the hacker when he breaks into the system under WEP and has the conversation balloon, "You're an idiot"! Hehe. I was rolling.

WEP: wired equivalent privacy, earliest protocol. 40 bit encryption, too weak no longer used.

WPA: wifi protected access. Uses TKIP (temporal key integrity protocol) to keep changing the keys as its being used.

WPA2: stronger than WPA, uses AES (advanced encryption standard)

WPA3: most advanced

WPS: designed for people who know little about wireless networks, doesn’t require entering a password. Requires pushing a WPS button on the router and on the printer/device to connect the router and printer.

Access control: can block specific MAC addresses from getting on the network

There are some important security issues missing from the more common standards.

WPS is even worse than WEP imo im usually able to get into any WPS Router in Seconds.

The pin for WPS cannot be changed, most routers can be tricked into revealing the encrypted pin and the pin is always 7 numerical digits and a checksum digit that can be computed from the previous 7 digits.

Also the pin is split into two before it gets encrypted so only 11000 numbers have to be guessed before you are guaranteed to have the password.

WPS is also turned on by default on most devices that support it and can't be turned off on many routers. Also once you have the pin, you can ask the router for the wpa/2/3 password and it will reveal it.

WPA2 is also insecure. Everytine someone connects to a router the hashed password (eapol handshake) is revealed. To everyone. Even to people who aren't connected to the network. This password can be cracked by a sufficiently strong computer. If the password is very strong, it might take too long, but most wifi routers have horrible passwords or even use the hilariously insecure wps pin as its default password (TP-Link for example).

Another issue is that you can disconnect other devices from a wpa2 network through deauthentication even if you're not part of the network yourself.

Acces control is entirely circumventable by mac spoofing. Many Android phones do this by default for privacy reasons already.

WPA3 is more secure, and fixes many WPA2 fuckups, but nearly no one is using it even tho its five years old now. It also already has vulnerabilities (dragonfly).

Long story short:

use a very secure password on wpa2/3.

Don't use WPA/WEP/WPS

Access control is useless against anyone who knows how to use google and a computer

If your Router doesn't let you disable wps throw it in the trash

WOW. I have viewed several of your tutorials and I am totally blown away by how good they are. With your tutorials, you remove the complexity of the internet and how all the devices( PCs, printers, cell phones, etc.) are tied together and tied into the internet . They simplify, clarify and with illustrations perfectly and concisely explain things. Thanks.

Dude currently in school for cyber security and any time I come across something I don't understand (which is all the time since I'm completely novice) I type it in the search bar and your videos come up. literally every thing I have searched you have a video on. You are a life saver!

[abdulbasitdalvi]

Wow this video brilliantly distills nearly everything important about wifi security in such a short video. Amazing man, keep up the good work.

I now generate a QR code for my WiFi instead of giving visitors my WiFi pass code👌🏾

Explanation is so well even a lay man can understand & learn easily ..

[Srikanth-lbgl]

Dear Sir..
Please explain about VPN and create a video on VPN
Thank you

[aaronbarragan]

I’ve learned so much in one day by binge watching your videos, great job!!!

[lagstorm]

1234? That's the stupidest combination I've ever heard in my life! That's the kind of combination an idiot would have on his luggage!

Love your videos man. Thank you.

[MrVP-doeb]

Your Video is Amazing
I am From India
I can understand your Video
Quickly with your animation work's

Please do more videos like This brother ...

[michaelduckworth]

how come those MAC addresses (8:07) have letters 'g' and 'p'. I thought hexadecimal only goes to 'f'. Am I misunderstanding something?

[cirotorres]

Simple and clear explanation. I think I’m in love

[darkestknightishere]

Simple, easy to understand yet very powerful video and presentation. Thanks again for uploading. Your voice is very clear and accent is easy to understand.. better than my tutors.

[Burgercat]

why dont ya try to use 16:9 in ur videos? btw very good explanation! :)

[Ginger_Dalek]

I've owned several routers & a multitude of Wi-Fi enabled devices over the years. In all that time I have never once got WPS to work. Seems to me to be the most useless "feature" ever.

[djahyeahh]

Hello,
just wanted to let you know that your videos have been extremely helpful to my learning. You are awesome :-)

[adymorris]

You've continually impressed me your content, visuals and simple explanations.
Thanks x
