What is Two Factor Authentication?
In today’s digital age, maintaining the security of our online accounts is paramount. One of the effective methods to enhance the protection of sensitive information is through the implementation of Two Factor Authentication (2FA). This reliable and advanced security measure adds an extra layer of security to your accounts, reducing the risk of unauthorized access and potential data breaches.
Two Factor Authentication is a security feature that requires two different types of credentials, or “factors,” to verify your identity and grant access to your online accounts. These factors can be categorized into three main types: something you know, something you have, and something you are. By combining two of these factors, 2FA ensures a higher level of security compared to traditional username and password methods.
The first factor, something you know, typically refers to a password or a personal identification number (PIN) that you create. It is a piece of information that only you should know, and it acts as the initial barrier against unauthorized access. However, passwords can be weak, easily guessed, or compromised, which is why relying solely on this factor is no longer considered sufficient.
The second factor, something you have, introduces an additional layer of security by requiring a physical device or object. This can include a smartphone, a hardware token, or a smart card that generates a unique code or performs a biometric scan to validate your identity. These physical items add an extra level of certainty, as they are in your possession and should not be easily duplicated or obtained by others.
The third factor, something you are, focuses on unique biological characteristics that are specific to individuals. This can include fingerprint or iris scans, voice recognition, or facial recognition. Biometric authentication offers a high level of security as it is difficult to forge or replicate these intrinsic features.
By combining two of these factors, Two Factor Authentication reinforces the security of your online accounts.
