This method of verification is user friendly, considered the most secure type of 2FA, and does not require an internet connection. On the downside, anyone that has access to the user’s phone or computer can compromise your account.ĢFA via biometrics – This type of 2FA is an up-and-coming technology that utilizes a user’s biometrics as the token – the user’s fingerprint, retina, and facial or voice recognition. The user immediately receives the auto-generated verification passcode and does not have to wait to receive an SMS or email.

Once the user enters this code into the online account, they have access. The authenticator app generates an OTP – typically six to eight digits – that refreshes every 30 seconds. When the user logs into the online application from an unknown device, they are required to open the authenticator app on their mobile phone (or on the computer as well as with Authy). In addition, it is easy for the verification email to go to a user’s spam folder and, of course, if an attacker has access to your email accounts, they will have access to the online account as well.Īuthenticator app / TOTP 2FA – This method of verification requires the user to download an app, such as Google Authenticator, Microsoft Authenticator, Salesforce Authenticator, or Authy as examples. This method has the same pros as SMS 2FA and 2FA via phone call, except that an internet connection is required to receive the verification email. In some cases, a user can click a unique link in the email to grant access to the account in lieu of a passcode.

This method of verification has the same pros and cons as the SMS 2FA verification method.ĢFA via email – 2FA via email is like 2FA SMS or 2FA via phone call, where the user receives an email with a secret code or one-time password (OTP). Most recently, a flaw in this method of authentication was discovered where SMS services could let hackers take over phone numbers in minutes by simply paying a company to reroute text messages.ĢFA via phone call – This method is like SMS 2FA, except the user receives a phone call to receive the verification code. However, a user requires cell reception to get the verification message, and if they lost their sim card or phone, they can no longer access the verification message to authenticate.

This method of verification is popular, as most individuals have SMS-capable phones, and the user does not need to install an app on their phone. When the user logs on later, they are asked to enter a verification code (usually six digits) that is texted to the user’s phone. SMS 2FA – This method of verification asks the user to provide their phone number. It is also easy for a user to lose or misplace the hardware device. Since it uses a hardware token, it tends to be one of the most secure 2FA methods although it can be expensive for a business to set up and maintain for every user. This method of 2FA is easy to implement and does not require an internet connection. When a user tries to access their account, they enter the displayed 2FA verification code from the device into the application/account. It uses hardware tokens like a key fob, which produces a numeric code every 30 seconds, or it can be plugged into a computer. Some applications let the user choose which type of verification they prefer while other applications offer just one type of verification.ĢFA via hardware – This is one of the oldest types of 2FA. If your phone is lost or stolen, no one can access the verification code without knowing your mobile phone’s password to open the verification text or authenticator application. If a user’s password is stolen, the thief will not be able to access the user’s account because another verification method is required. In some cases, 2FA sends a text message to the user’s mobile phone.ĢFA is the most highly recommended defense to block an attacker from hijacking a user’s account. With 2FA, a user logs into the online account but instead of getting immediate access, they must provide additional information, such as a personal identification number (PIN), a one-time verification code, answers to questions that only the user knows, and so on. Two-factor authentication provides a second layer of protection for a user’s online accounts – above and beyond the user’s password.

This includes something the user knows and something they have access to. Two-factor authentication (2FA) is a feature that requires a user to present two different types of identity evidence before being allowed to access an account.
