Google Authenticator - A widely adopted standard across major websites. Authy - Easy to use, feature-rich and supports multi-device sync. The code is usually a six-digit time-based, one-time password (TOTP).īefore getting into how we chose them, here’s a rundown of our top five picks: Every time you log in, your app will automatically generate a code, which you’ll need to enter to unlock your account. After turning on 2FA on your account, you can scan a QR code to tie that account to your app. Two-factor apps use one-time passwords (OTP) as your second factor. We’ll also briefly touch on hardware keys that use either a hardware token or fingerprint scanner to approve your login. These apps work on iOS and Android, usually providing you with single-use codes or push notifications on your mobile device. We have a deep dive into what two-factor authentication is if you need more information.įor the purposes of this guide, we’re focusing on 2FA apps like Microsoft Authenticator and Authy. There are some differences between factors, and there are even differences in how one-time codes are generated and sent to you. It works by combining two of the factors listed above, so you might use your password as your main factor and a 2FA app as a secondary factor. Most websites support 2FA in some form, including Amazon, PayPal, Reddit and all major social media platforms. Something you are: your fingerprint, face scan, etc. Something you own: your mobile device, a 2FA app or a 2FA hardware key. 
Something you know: usually your password.They’ll also need your second factor.Īlthough multi-factor authentication tools like OneLogin consider everything from the IP address of the login attempt to the time of day, there are three main factors most online services use: For example, if you have a compromised password in a data breach, the attacker won’t be able to unlock your account with your password alone. Instead of using just a single factor to authenticate your identity, like a password, you use two different factors, usually your password and a one-time code sent via SMS or email.īy spreading the risk across two factors, it’s much less likely that an attacker will be able to unlock one of your accounts.

Two-factor authentication - or two-step verification - is a security feature that adds an extra layer of protection to your online accounts. More commonly, 2FA is vulnerable to account recovery attacks and phishing schemes. Two-step authentication can be hacked through man-in-the-middle attacks, though this is becoming increasingly less likely.
