Unlike Apple, which only after breaking into iCloud has increased the security of its services, Google has long been offering a two-tier user authentication system. However, in the light of the recent events, the online giant has, however, considered that this may be an inadequate way, so it offers all users a hardware key.
Previously, Google’s online services, such as Gmail, were protected by a two-tier authorization system, so in addition to the standard password, a user who had activated this option must also enter the code that was sent to his phone. This makes it much more difficult for hackers to gain access to our account.
However, Google believes that its system needs additional reinforcement, so it adds a hardware key in the form of a USB device. Then access to your email account and other services is only possible when the Security Key is attached to our computer. Interestingly, the company also ensures that this method also protects against phishing, and thus using our data on a specially crafted, fake version of the site.
The new method only works with the Chrome browser and Chrome OS, and you can get more information on the official Google blog.
