Its major businesses include the design, development and sale of consumer electronics, computer software, online services and personal computers. In today's highly developed Internet, an account should be one of the things that we have the most contact with in our weekday life, and it is also an indispensable necessity in people's life nowadays. Each application for an account will naturally have a corresponding password for logging in. But nowadays everyone has to deal with dozens of different platforms in their life and work at the same time every day to apply for each account, for the setting of the password will naturally appear a great deal of trouble. A consortium called FIDO (Fast Identity Online) is promoting and encouraging the use of two-step authentication. The FIDO consortium, which includes almost all of the world's top technology companies such as Google, Microsoft, Apple, Samsung, Alibaba, Intel, Lenovo, etc., is committed to standardizing two-step authentication methods. All Android and Microsoft devices are equipped with FIDO's standardized two-step authentication method, with biometrics being the main type. Users of these devices are able to log in using their fingerprints or facial recognition at will. Even the U.S. government is now adopting the FIDO standardized authentication method, and one of the major advantages of the FIDO standard is how it stores the information the user uses for authentication. Traditional password authentication usually stores the user's password information on a server, and the leakage of the user's personal information is often caused by the server being invaded by an outside party, while FIDO stores the user's personal information locally in the user's hand, which means your fingerprints, face, and voice information.
