An intruder can easily copy them if they are in physical vicinity and use them to gain access to your account. But what do you do with the websites which do not support backup codes?Īnother point against Google Authenticator backup codes is – they are as secure as a password written down on a paper. Some of these websites provide backup codes, and a user can gain access to these websites if his/her smartphone is lost. It is imperative to understand that Google Authenticator is a multi-token, thus you can enroll many tokens for various websites using one app. Operating principle is pretty much the same for all the software OTP tokens – they generate authentication codes for logging into your account right on your smartphone. – Newton Lee, Counterterrorism and Cybersecurity: Total Information Awarenessįrom all available options of one-time passwords generation or delivery (SMS, emails, hardware and software tokens) most people choose Google Authenticator or other similar applications like Authy, Protectimus Smart etc. “As the world is increasingly interconnected, everyone shares the responsibility of securing cyberspace.”

So why two-factor verification is still unpopular? Sure, it creates an extra step to take to log in, but most users omit it not because of this extra time and effort, but because they are afraid of losing access to their credentials if something goes wrong with their authentication devices. It also complicates man-in-the-middle and man-in-the-browser attacks.

Thus, two-factor authentication protects from brute force, keyloggers, most cases of phishing and social engineering.

If you use two-factor verification, an intruder would need to get both the unique password you came up with, and the gadget, which produces the verification codes, to break into your account. In the contemporary world, where database leaks are a standing affair, two-step authentication is not an option, it is, in fact, a must. Our regular readers know that we strongly recommend applying two-step verification wherever it’s possible.
