History has shown that passwords aren’t always enough. Cybercriminals can guess commonly used passwords, find passwords that have been written down or shared, or deploy brute force attacks that use a script to enter all possible password combinations. 2FA works to mitigate these threats by adding an additional layer of identity verification. The most common platforms for deploying a 2FA solution include:
As mentioned above, when a user attempts to log in to your network, they are prompted to enter the unique code that’s sent to their email address or mobile device. Upon entering the correct code, the user is granted network access. The user may also have the option to label the device they’re using as trusted, so they won’t have to repeat the process every time they log in on that device. However, if logging in on a new, unrecognized device, they will be prompted to re-verify their identity. That means anytime a cybercriminal attempts to log in, they would also have to have email or cell phone access to infiltrate your network.
Authenticator applications work similarly to verification codes. Users download an authentication application to the mobile device of their choice and link their accounts to the application. Whenever they attempt to log in, they will be prompted of an attempted login, the location of the attempted login, and given a code to verify that they are an authorized user. An authenticator app also allows for multiple accounts to be synced on one device, making it easier for your team to verify logins if they depend on multiple network platforms for day-to-day operations.
