2-step verification: Protect yourself

2-step verification: Protect yourself

The Internet about 10 years ago was only for accessing information, news, sending & receiving emails or entertainment; today these are not the only reasons. We use the Internet for financial transactions - online banking, online shopping, and virtual cloud servers for storing confidential information or photos/videos. As our interaction with the virtual world is increasing, the security becomes more essential and crucial. Today the long alpha-numeric passwords are also vulnerable and can be hacked or known to people close to you.

To ensure more security, a new method is being implemented by most websites, called the 2-Step Verification. This method adds a second layer of security over the already existing passwords. The 2-step verification requests the user to provide a dynamic code along with the regular password. This code is generated instantly, and expires if not used within few minutes.

What is 2-step verification?

Reference Wikipedia - "2-step verification is a process involving two subsequent but dependent stages to check the identity of an entity trying to access services in a computer or in a network with just one factor or secret, whilst there is no proof obtained that the bearer of the unit is identical to the owner of the unit."

In general terms, 2-step verification allows users to have a password and an additional on the fly code. This acts as a secondary password for authentication as a user. The mostly numeric (at times alpha-numeric) code is pushed to the user from the website via an SMS, email and / or using authentication applications. This code is generated instantly and is valid only for a short duration. The code expires if not used within the stipulated time frame.

This is similar to the authentication tokens (USB sized device) provided by select banks to its online banking customers.

Most of the websites have begun implementing the 2-step verification. Google was the first Internet company to introduce the 2-step verification process, for its internal usage and then rolling it out to the general public. To get a comprehensive list of websites offering or in the process of offering the 2-step verification, visit TwoFactorAuth

Once setup, 2-step authentication does offer better security. This security comes at a cost of an additional step; that is to enter the dynamic code along with the password. If someone knew your password, or managed to guess your password, they could access your account from anywhere. Now, they'll need to know your password and have access to your phone/computer (which itself would have a password/lock). If you access this account mainly on your personal computer/laptop, it can be set to remember the credentials. This bypasses the need to enter the password and the 2-step verification. The 2-step verification comes handy when accessing protected websites on public computers like at an internet cafe (if they still exist), a friend's computer or at work.

Ways to access it - SMS/Email/App

2-step verification can be setup via multiple methods. This method is defined by the website offering the security. Few websites offer to set up your mobile number for the One Time Password to be shared via SMS. Some websites allow setting up an email address for the same purpose after verification of the email account. Another option offered is via a mobile-based application. This application is verified by the website and once setup, the dynamic code is refreshed every few seconds or minutes.

Google offers to set up 2-step verification via SMS and their own application called - Authenticator (available on Android & iOS). While Authenticator is developed by Google, the application can, however, also be used for setting up 2-step verification for other websites like Facebook etc.

There is also a third party application Authy This application is available for iOS, Android, Blackberry, Mac OS X, Windows, and Linux as well. Authy is more versatile compared to Authenticator and is available for more platform along with additional features missing in the Google's own application.

Apple, on the other hand, offers 2-step verification only via SMS. This process requires you to use the One Time Password shared whenever you wish to access your account.
