Have you ever witnessed someone use a tiny device to log in by tapping it or plugging it into a USB port? Have you ever wondered why they require such things?
The most reliable form of authentication that is currently available is through hardware security keys.
Continue reading to learn what hardware security keys are and why they might be the best investment you make in security.
Hardware security keys: what are they?
Hardware security keys serve as proof that the person trying to access the account is genuine and not a criminal.
It offers both two-factor and multi-factor authentication methods. When you log into your account, it adds an additional layer of security by requesting a PIN code or using biometric authentication.
Hardware security keys are available in multiple varieties, such as Bluetooth, NFC, and USB keys. While some security keys are more flexible and can be used with a variety of platforms or devices, others are more device or platform specific.
The use of these keys, however, is not universally supported by all devices and platforms. However, more and more people are using them, including password managers like Locker.
Should hardware security keys be used?
The answer is yes. Hardware security keys are a low-cost, high-return investment in your cybersecurity. It will also reduce the administrative burden associated with authentication.
Other types of two-factor authentication, such as SMS text messages or authentication apps that require another device, may have been introduced to you.
Using hardware security keys is far more convenient than these methods because you can unlock your device without having to wait for a text message or rush to get another device for authentication. Instead, you can unlock the device with a simple tap or plug-in of the key, followed by the entry of a PIN code or biometric ID.
Hardware security keys are also more robust than traditional authentication methods.
Why? Certain types of attacks, such as phishing or SIM swapping, are less vulnerable to physical keys. At the end of the day, providing a "possession factor" to establish that you physically own access to the credentials is the most trustworthy form of authentication.
Consider your account to be a fortress containing valuables and confidential documents. Only those who have specially made brooches with fortress symbols are permitted to enter the fortresses. These brooches are hardware security keys that allow your device to recognise who is allowed into the gated fortress.
What if hardware security keys are misplaced or lost?
In addition to your account login credentials, your hardware security key is functional. So, if someone steals your key, they won't be able to access your accounts unless they know your username and password.
Furthermore, if you misplace your security key, you can always use a backup method of two-factor authentication. You can then access your online account, remove the linked security key, and either add another or continue to use a backup method.
