Securing your account with password only? That’s not enough anymore - Use two-factor authentication

Using userID and password only to login to your account is old method to ensure security to your account(email, bank, facebook, etc.). It has been reported numerous times that passwords can be stolen, leaked, cracked, captured, sniffed & guessed. Bad guys (may be your own people with bad motives) are trying hard to get your password and get into your account to steal data/money/identity/photos.

You need to protect your account with something more than just UserID and password. Strong password is not enough to protect your account and you need to go beyond that to make your account secure.

What is two factor authentication ?
In simple terms you can consider two factor authentication as "Two Locks" for your account. You need to open both the locks before your get into your account. And to open two locks you of course need two separate keys.

Two factor authentication is security process in which you use your userID+Password and physical token. Its "something you know" and "Something you have". E.g. If you wish to login to your email account, your emailID & password is what "You know" and an addition short numeric code(Verification code) that is available on your phone which acts as "You have".

Why two factor authentication?
According to security research, two factor authentication drastically reduces the risk of your account getting exposed or hacked by anyone. Anyone who knows your userID+Password, now cannot open your account unless they enter the code which only you have it(on phone or physical).

Banks, enterprise business, and small/medium business already got this started early on and now lots of online companies provide this feature for free to users to increase level of security around your accounts. Your data & identity is equally important as your bank account, which you don’t wish to loose.

Why anyone cant break into your account with two factor authentication ?
By adding a second lock to your account it gets hard for anyone to crack your account. Numeric code is usually generated every time and it keeps changing. Anyone who has your userID & password also now needs this numeric code to open your account and that’s not with them(unless your phone/device is lost).

Here is a short video on Two factor / Two step authentication from google.

How does Wi-Fi works ? 
Wi-Fi is preferred wireless way of internet connectivity on mobile devices. We connect to Wi-Fi at home/office/cafe/Hotels and public places to get fast internet connectivity and do all stuff using it. Usage of Wi-Fi has spread fast with smartphones/tablets as compared to laptops couple of years back.

Wi-Fi uses network name (SSID) and shared-password to connect and that makes it easy for users to get internet without much hassle. Once you connect to a network, your mobile device remembers the network and tries to auto-connect to it whenever its available.

Mobile devices store all this Wi-Fi network info and use to auto-connect on periodic basis so as to provide preferred connectivity; and all that happens behind the scene. May be its your android/iphone/blackberry/windows phone/tablet all work same way. Your phone tries to connect to Wi-Fi automatically.

You can see list of Wi-Fi networks connected by your device going to settings > WiFi
