While SMS code and authenticator apps are popular options for two-factor authentication, they have some weaknesses and limitations. A more secure option is a safety key – a physical device that approves the login with a quick tap. Here you should get this device to protect your accounts.

Strong more than other 2fa methods
To understand why a safety key is a more secure option for traditional two-carnimate authentication (2FA) methods, you should understand how the key works through public key cryptography. When you enter the safety key with a service, the service stores a public key on its server, while the private key is safely stored on your device.
When you log in, the service sends a challenge that can only be answered from your safety key with a personal key. In comparison, SMS-based 2FA SIM is unsafe for swapping attacks. While the app-based certification is safe than SMS, it still needs to manually enter into such codes that can be intercepted when your device is compromised or lost.
Security keys eliminate these risks, making them the best option to protect their accounts from cyber criminal that develop new ways to bypass 2FA methods continuously.

Immunity for fishing attacks
Traditional certification methods often decrease when it comes to fishing attacks. You can be cheated to visit a fake site that looks like real, and without realizing it, enter your login details. If you are using SMS or app-based 2FA, the attackers can capture and use your code to reach your account.
On the other hand, the safety key makes the fishing almost impossible. They use cryptographic verification between key and valid website or service. They work only when you are on the valid website of service where the key was initially registered. If you are on a bad site, the key will not work – there is no authentication.
Therefore, while a safety key removes the weaknesses associated with traditional methods, it also protects you if you accidentally end on the fishing site or fake login page.

Log in your accounts in a flash
If you have used the traditional two-carrier authentication methods, you are probably familiar with the disappointment to wait for an SMS code, which sometimes, sometimes not, or quickly trying to enter a code from an authentic app, before it is refreshed. In addition, there is a challenge to correctly remember and enter the six -digit code without the risk of locking from your account.
Conversely, a safety key simplifies the authentication process, allowing you to log in within seconds. You simply enter or tap the key, which uses cryptographic communication with the service you are logging in, and you are given access. There is no wait for the code to come or refresh, and there is no risk of closure to enter the wrong code.
Some platforms such as Microsoft and Google support the password -free login using the safety key, which is another strong reason to invest in one.

Protect many accounts with single key
We usually use several authentication applications or phone numbers for various accounts, and when this happens, managing different 2FA apps, handling different codes within an app can also become a problem. And if those apps or numbers are tied to other equipment, you will need to carry them.
A safety key eliminates this problem, as you can register it with several services and platforms that support hardware-based 2FA. When it is time to log in, you put the key in your computer and become certified in seconds. In this way, you do not have to avoid many devices or deal with various authentication apps.
It also simplifies monitoring and gives you better control which accounts are connected to your safety key. Whenever necessary you can cancel access to specific accounts.

Work without phone, network or app
The safety key itself does not rely on any network, battery, or certification app, so you are less likely to be locked out of your account because you do not have your own phone, it is out of the battery, you are in the area with bad signal and cannot get an SMS code, or the authentication app you are using is acting.
If you often travel to remote areas, where you face these issues, using the safety key for authentication can help eliminate these problems. The major offline works and is self-contained, but your device requires internet connection to communicate with the server of service and complete authentication.
In short, as long as your device has internet access to connect to service, you will not have to worry about the above mentioned issues.
So far, you should clearly understand how a safety key provides better protection than traditional authentication methods. To decide you will be better whether it is worth buying.
Remember that while other 2FA methods are free, a safety key comes at a cost. However, the peace and protection of the mind provides this. It is worth investing.
