Think!!! How it is when there is no need of any password to login to a computer system or online account. Search giant Google now takes steps to make a hardware device which can be used to login to a computer or any online account without need of any password.
Google's trial was focused on a slim USB key that performs a cryptographic transaction with an online service to prove the key's validity when it's plugged into a computer.
The key also has a contactless chip inside so that it can be used to log in via mobile devices. Tokens like the ones Google is testing do not contain a static password that could be copied.
The cryptographic key unique to the device is stored inside and is never transmitted.
When the key is plugged in, it proves its validity by correctly responding to a mathematical challenge posed by the online service it is being used to log into, in a way that doesn't produce any information that could be used to log in again.
Google is already talking with other companies to lay the groundwork for using the technology to access different services and websites.
