How Safe Is Two Factor Authentication?

Two-factor authentication is often pushed as a means to secure online accounts. And, for the simple reason that it adds an extra security layer to your account. In simple words, even if someone got access to your account’s passwords, they would still have to bypass that extra layer of security – a code if you will that is sent to you via text (or phone call or via an authenticator like Google Authenticator). But, turns out hackers seem to have found a way to intrude that extra layer of security too. So, now the question arises – Is two-factor authentication safe?  We’ll discuss how safe two-factor authentication is and a lot more that might help strengthen your guard up against cybercriminals and their vicious attacks. So, read on.

How Can A Hacker Bypass Two-Factor Authentication?

We’ll begin with some of the most latest attacks through which hackers were able to invade the two-factor authentication and then we’ll look at more such ways –

SIM Swapping

SIM Swapping is an attack in which a hacker can impersonate you and then he convinces an employee at a carrier to switch the phone service that you have to that of a carrier. Once that happens, the hacker has access to all your messages. Do have a look at two of these instances –

In another instance, a hacker was able to hack into a user’s text for just a matter of USD 16. Here the case was different from regular SIM swapping. Instead, the hacker utilized a service that is intended to help businesses do mass messaging and SMS marketing. These are the whereabouts of the case.

Social Engineering

Here broadly, there are two situations. In the first situation, the hacker is aware of your username and password. This means you still have that third layer of security to protect yourself. In that case, the hacker would send an alarming message that your user account has been accessed by a suspicious IP, and then further, you will be asked to reply with a code sent to your mobile number. That’s one way of getting to bypass two-factor authentication.

In a second way, the hacker might send you a phishing mail or rope you in a legit-looking website. Once you log-in on this website, the hacker gets access to your credentials which he then uses on a real website, after which the real website sends you a code. Once you enter the code on the fake website, the hacker can bypass the two-factor authentication.

Now, that we have stated the problem, let’s have a look at some of the probable ways to prevent ourselves. Read on!

Physical Security Keys

If you can get your hands on physical security keys, there’s nothing like it. These prove to be a more secure second step. Hardware-based keys have several passwords stored in them and as one of their features are also able to easily discern between real and fake websites. They are positively more secure and stronger than software or SMS-based options.

Use A Password Manager

Consider this – your smartphone is lost or stolen and now it is in the hands of a probable hacker, who can easily look into the code being sent. Scary, right?

If you use a password manager like LastPass, each time it will generate a very strong password because of which the hacker will have a hard time bypassing, say, your authenticator app. Secondly, a password manager like LastPass eliminates the need to manually typing in the password.

Don’t Ever Give Into Phishing Mails

Especially the ones that ask you to furnish codes in the mail. Whether you are an employee at an organization or an individual, you must make yourself aware of how you can save yourself from phishing attacks. If there is a mail that looks suspicious or a mail that has come from a source that you don’t know, better not to click on it.
