YubiKey 5 NFC Two Factor Authentication

The two-factor authentication can be made as simple as possible by a device called the YubiKey 5 NFC Two Factor Authentication. Instead, a code generated by our phone through the application, and not the code that was sent to you, you just need to press a button on the YubiKey. 

A unique code is built in each device which has the function to help you to confirm your identity by generating code, you can log in by pressing the button. We can deep-dive into the math and a device like this that supports various protocols can be broken down.

But, many users do not want to know more than entering a password and username, as usual, you will be able to login by pressing the button on this device. To access many coding tools, a YubiKey 5 NFC Two Factor Authentication  is required.This device which is called a two-factor authentication device is not the only one in the market. There is several similar devices out there, but this is one of the best of those devices.

About YubiKey 5 NFC Two Factor Authentication

To go over the basics of the two-factor authentication, it’s necessary before understanding two-factor authentication devices. Passwords are bad. Hacker can guests easily by using most passwords. To remember humans, the rest is too complex and too long. A secure password, after a leak, it is useless, and the leakage is possibly inevitable. So, it is better to not to rely on a password entirely because of these reasons. That is the whole idea behind this 2FA or the abbreviation of two-factor authentication.

With these factors, YubiKey 5 NFC Two Factor Authentication needed to sign in. Definitely, you need a password, but, there is also another thing as a verification that who you say you, are you.

When it comes to doing Two Factor Authentication (2FA), here are two ways. The first is email codes or SMS. A code is sent to you by apps. You need to enter it before login. to set it up, there is an easy method because you don’t need to purchase or install hardware or software.

It gives the least secure since both of them are easily compromised and unencrypted. Second is authentication apps, if you want to log in to the apps, a code will be asked to you. To get the code you can open the app on the phone like Aunthy or Google Authenticator.


Using YubiKey 5 NFC, the Great Hardware Two Factor Security Key

Instead of relying on email or SMS, this device gives more security, but, the most convenient is not this, you have to get your phone, open the app, and typing code. You can do 2FA by using a third way, it is the YubiKey 5 NFC Two Factor Security Key, the hardware authentication.

A tool like YubiKey is required by the apps to plug into your device and then pressing a button. A unique code is sent by YubiKey so that your identity can be confirmed by the service. It gives more security. 

The code is more convenient and longer and you don’t need to type it by yourself. There are more nuanced than this. But, the important thing you need to know is that it is two-factor authentication that is easier to use and more secure.

The Excellence of a YubiKey 5 NFC Over Another Two Factor Security Key (2FA)

This has been covered a bit, but, let’s talk about the excellent of this device or in other words why it is better than other forms of two-factor authentications. Some of them are mentioned as following.

1. Convenience and Longer Codes
Authentication apps, email, and SMS all required that you manually enter or that you copy then paste, a code. You just need to push the button on the attached- YubiKey 5 NFC Two Factor Security Key on your computer, typically, a six-digit code is sent by some2FA methods as a confirmation of our identity.

The particular of those methods is because humans can’t type more than the number of those codes. You aren’t asked to type a code manually. So, to use longer codes, they are free and more secure.

2. Can Migrate Easily and Hard to Hack
Do you have a new computer? if so, then you need to use YubiKey 5 NFC Two Factor Security Key by plugging it from the old one and after that, just plug it into your new so that you can log in easily to all apps you have previously, same as before.

It is also possible for your account to log in on to multiple computers by using one key then migrating using other 2FA, using this device, the process is easier. More than that, both of SMS or email is easier to be compromised by a hacker. 

But, by using today’s technology it is much harder or even impossible to fake or cheats codes created by a unique hardware device. Again, there is a lot more to the nuance here, but this is the YubiKey 5 NFC’s Two Factor Security Key broad advantage over other forms of two-factor authentication.
