Google has been working on alternative Mechanisms to the regular Password, and just recently, it launched Titan keys, the phishing-resistant two-factor authentication devices that help protect high-value customers from the most sophisticated cyberattacks.
While the user experience for the Titan keys is rather not pretty convenience, and since you have to connect a physical key to your device, the downside remains the fact that you'll need to carry the physical key, which is liable to get lost, and in such situation can get you locked out from your online activities. Albeit, Google assured that there are backups with an extra key that can help you gain access to your account, but the recovery process can take days or even weeks.
Now, the company has also made it possible for Android users to turn their gadgets into a physical security key, which feature requires devices running Android OS version 7+ with Bluetooth and location services fully enabled.
The setup process isn’t any different from that of a regular security key, as you’ll still need to have a replacement second or third key in case your phone get lost or destroyed. So you’ll be able to gain access into your account, as the new feature works for both G Suite enterprise customers and personal Google accounts.
To set up the physical security key using your Android phone (it requires Android 7+), simply switch on the Bluetooth and connect it to your computer, then open Chrome browser on your computer and sign into your Google account. Go to https://myaccount.google.com/security and select two-step verification - on the menu choose add a security key and select phone. That's it!
However, the service is currently available for Google accounts only, and there is no timeline when Google will expand it to cover other online accounts. But you can still avail yourself the use of the Google Authenticator app with 2-step verification for services like Facebook and WordPress security.
It is also expected that Google will integrate it into other browsers, even as it has enabled support for signing into its own service using the Titan security keys on Microsoft Edge and Firefox.
