Google: Security on USB flash drives

Google announced its intention to adopt a new form of strong two-factor authentication technology conforms to the Universal Second Factor developed by Fast IDentity Online (FIDO) Alliance. U2F allows Chrome users to secure access to their Google account through a physical device such as a security USB flash drive. The FIDO Alliance was formed in February last year with the aim of enabling more advanced forms of authentication for the user to ensure access. While the safety key is still an option for users who want a more secure authentication, the current Google Authenticator method can always be adopted.
