It requires both “something you know” (like password) and “something you have” (like your phone)” – By Matt Cutt.


Lots of websites recently started this service so here we have few steps for enabling 2 factor authentication:

Twitter’s 2 F.A. Sends you 6 digit code via text message when you try to login from another machine. You can enable 2 F.A. By clicking here.



Please note if your device having access to your accounts is lost then revoke access as soon as possible. 2 F.A. Is not easily broken but for hacking bad guys must acquire either the physical component which is used for log in or gain access to cookies. This can be done by few ways like phishing attack, malware, or by misusing account recovery. Account recovery is one the best trick for gaining access as account recovery resets the password gives you a temporary password. “I see bio-metrics as interesting way to solve the recovery problem. If I lost my phone it would take forever to go through every account and recover them. If there is a very strong bio metric recovery method, a passcode of my choosing and a voice challenge, it become a very reasonable and usable recovery mechanism.” Jon Oberheide Co-founder of Duo security

There is no question that 2 F.A. adds bit inconvenience to your log in process but i think it’s worth that much as it is one the best ways to keep your data safe.
