As you become increasingly dependent on the internet to execute your day-to-day functions, you also become increasingly concerned about the security of your data, devices, and systems. This is especially so since there are increased reports of cybercrime incidences targeting businesses and individuals as well.
Fortunately, cybersecurity solutions are also being developed to match the increasing cyberattack threats. Different authentication factors (FAs) have been developed to keep users and online resources safe from cyberattacks. Some of them include Google and Microsoft Authentication Apps.
Keep reading to learn how these Apps work. First, let us look at different authentication factors.
Authentication factors refer to the processes used to keep users’ credentials safe and secure online resources from unauthorized access. Some platforms require a single-factor authentication (SFA) in which the user provides a passcode or PIN.
Some may require two-factor authentication (2FA) that combines your Pin with another factor like a biometric factor, such as voice recognition, fingerprints, or face recognition. On some platforms, you need multiple-factor authentication (MFA), meaning you require a combination of two or more factors to access a system or online resources.
Here are the authentication factors most platforms use:
A single-factor authentication can use any of these factors. 2FA usually combines any two of the first three factors, while MFA can combine any of these factors to create several layers of protection.
2FAs may be divided into hardware and software-based 2FAs. Hardware-based 2FAs include smartcards or key fobs. On the other hand, software-based 2FAs exist in the form of desktop or mobile Apps. The Apps generate a one-time password (OTP) they link to a specific device, account, or user.
The OTP is shared with the user, who may input it any time they require access or authorize the system to save it and remember it anytime the user wants to log in. An example of an OTP-based system is your Gmail account.
However, the OTP is not the only factor the system uses. The software-based Apps also generate a code that they save in their platform. This combines the user’s OTP, device identity, and security issued during the account registration. When you request access, the system inspects the security key, the initiating device, and the OTP.
If they match, access is given. If one of the sets of information fails to match, the system sends you a notification. You have probably seen this if you ever tried to access your Gmail account from a new device. This authentication is not secure since the OTP may be intercepted and used to access your account without your authorization.
Some 2FAs Apps go a step further to secure your data by generating a Time-Based One-Time Password (TOTP). The system generates unique passwords at regular intervals, and the passwords are not shared with the user.
Hackers cannot access the passwords since the platform uses them only as internal authentication factors. The TOTP combines your password, location data, device and account information, and the time when the code is generated to determine if you are authorized to access and continue using a platform or online resource.
When you sign-up on an authentication app, it notes and stores your credentials. Every time you request access, the system a TOTP. If the TOTP on the originating device and the system match, you are granted access.
Remember, the TOTP is shared between the server and the authenticator, eliminating chances of the information being intercepted by the MitM for unauthorized or malicious use. This tells you that platforms using TOTP, like Microsoft and Google authenticator Apps, are more secure from cyberattacks.
