Google has announced a physical USB Security Key that should ensure users keep their accounts safe from hackers, although it is not without its limitations.

Anyone who buys a compatible USB from a third-party supplier and adds the Security Key functionality will be able to use it when logging in to Google’s sites, which include Gmail and Google Drive, as it will hold the code required when two-factor authentication has been switched on.

Two-factor authentication is a security protection that asks for a password and an additional piece of information that verifies the identity of the person logging in.

Previously, Google has only allowed users to receive the second chunk of authentication data as a code sent via text message or the Authenticator app, but the USB can now be used without any input needed on the keyboard.
