Just add an account here or there until you’re covered. Remember, this doesn’t have to be a race, and it shouldn’t feel like a chore. Add one or two main accounts in your authenticator app until you get the feel of it, and until you get comfortable using it.Īfter that, you can begin turning on authenticator app-based 2FA for all of your other accounts. In fact, we’d recommend that you take things slowly at first. So what’s the good news? First of all, you don’t have to do this all at once. In other words, it will take some time, and you may have to do a little troubleshooting. When using an authenticator app, you’ll have to enable 2FA for each of your accounts individually, and the procedure will vary between accounts. This is where we come to the “good news/bad news” part of the process.įirst the “bad news” (though it’s really not all that bad). The next step is to begin turning on authenticator app-based 2FA for your accounts. Now you have the Authy app installed on your device, and you’ve linked the app to your mobile number and device.

Even if a bad actor managed to get hold of your password and redirect your SMS messages to their own device, they still wouldn’t be able to get your app-based 2FA codes, because those codes live exclusively on your mobile device.

They do this entirely in-app, meaning that the code is generated on your actual device, not on some company’s server - so it doesn’t have to be sent to you. Instead, they generate something called a “time-based one-time passcode” (TOTP). This is how 2FA-protected accounts can still be compromised by bad actors.ĭue to the limitations of SMS, authenticator app-based 2FA is considered much more secure. If successful, the attacker will start receiving all of their victim’s calls and text messages - including their 2FA authentication codes. In a SIM swapping attack, a bad actor attempts to reassign someone else’s mobile number to a SIM card that they control. That’s one of the reasons that Google has tried to develop a more secure alternative to SMS.īut there’s an even more basic security issue with using SMS for 2FA: SIM swapping attacks. And SMS is no longer considered a secure data transfer protocol.įor one thing, the SMS protocol itself is vulnerable to certain kinds of interference and manipulation by bad actors. The problem is that 2FA often relies on SMS messages to send those one-time authentication codes. But many implementations of 2FA have a pretty big security issue. Two-factor authentication is an excellent way to prevent account takeovers and breaches. And since the device is with you, and not the bad guy, they aren’t going to be able to log into your account - even though they have your password! If you do have 2FA set up, the bad guy will still have to enter the second authentication factor: that one-time code sent to your mobile device. They can enter your password, log into your account, and do whatever they want to do.īut here’s the thing. If you don’t have 2FA enabled, that’s pretty much game over. This can happen in a number of ways: data breaches, phishing emails, keylogger or malware infections, social engineering attacks and seasonal scams. Let’s say that a bad guy manages to steal your password. You have to provide both the password and the authentication code to log in. That usually means that you will enter your password as your first authentication factor - but then you’ll also have to enter a one-time authentication code sent to your mobile device. When you use 2FA, you need to provide two authentication factors in order to log into an account, website, or service.
