In today’s world of ever improvising tech, there’s also an ever-increasing risk of a threat to your online security. No matter how conscious and careful one is about their data online, there’s always a chance that they can be fooled by hackers into giving up some sort of crucial info like OTPs or passwords using a well-crafted phishing site.
For the uninitiated, phishing is a method used by hackers where they create a webpage very similar to the legitimate one you’re supposed to be visiting and entering your secure credentials into. This secure-data will go directly into the hands of the hacker and all your safe information is not safe anymore.
There are many ways to tackle Phishing attacks or just the theft of passwords. One of the most secure ones there is Two Factor Authentication. This is done in many ways, but the basic working of two-factor authentication is the same across all methods.
The two phases of authentication are:
- One, the actual password entry.
- Two, the identify confirmation.
The latter can be done in multiple ways and this is where innovation comes in to find better, more secure ways to confirm that the person initiating a login is the one that should be doing it.
Google takes extensive care with their 2-FA and they have a number of ways of doing this.
Of these, arguably the coolest and most secure is the requirement of a physical security key. Google supports its own made as well as third party physical security keys, which need to be plugged into the computer for the second layer of authentication. Lately, Google has made an extension for this feature. You can also now use your Android (7.0 or above) or iPhone (iOS 10.0 or above) as proximity enabled physical security key, so you do not have to shell out the extra money for the USB keys.
For this method to work, the phone has to be connected to the PC via Bluetooth for successful authentication making it a whole level of secure. Also, having Bluetooth enabled devices is a must for this.
This is very handy for content creators and people that have to travel a lot and need to log into numerous devices on a daily basis.
