According to the most reported, Google Chrome browser has set up a two-step security-critical authentication settings, which allows users to use a USB device. There will be a new login method using Google services on desktop browsers. That is, after entering the password, the user must insert a support USB key. The USB key is purchased online for as little as $6. Google has posted setup instructions on its website, as well as some frequently asked questions.
The previous service authentication required a verification code, and the user could receive the code via SMS. There are still problems with these methods. If your phone crashes and you cannot get online, or you forget to bring your machine to print the signature, you will not be able to log in successfully. In contrast, USB keys are easy to keep in touch with your Internet-connected device; it does not require online access to work.
However, USB login also has drawbacks. As Google pointed out that in all cases, USB-based login is not ideal. Mobile phones and tablets do not work because there is usually no full-sized USB interface, and now it does not work on any desktop browser, and the upfront cost is another obstacle. USB keys don't just support USB, including support for Bluetooth low and near field communications, it also supports it, so you may not need your verification code or insert anything in the future.
