Physical tokens as passwords for Google, Facebook!

Google and Facebook are reportedly working on password systems that would involve inserting physical tokens in computers providing better security to users.

The systems would let users access their favourite websites only after plugging in a special token that would be no larger than a memory stick and then typing their password.

According to Daily Express, the tokens are said to feature a cryptographic card, which holds security information and this changes over time.

While Microsoft is looking into the technology, Facebook and Google have already begun making their workers use the system.

Facebook security engineer John Flynn explained that they are keeping an eye on emerging authentication technology and hardware authentication is one of those.

Meanwhile, computer experts have said that the mooted system is the best way to provide extra security for users, especially after users have been found using 'dumb passwords'.
