In the forthcoming issue of a technical journal, Google's security engineers are set to publish a research paper which will detail the increasing concerns over online password security issues and the alternatives.

The Wired, which grabbed a sneak peak at the paper, said that the company is considering a ring-finger authentication technology to tighten online security.

"Along with many in the industry, we feel passwords and simple bearer tokens such as cookies are no longer sufficient to keep users safe," Google Vice President of Security Eric Grosse and engineer, Mayank Upadhyay, wrote in the paper which will release later in January.

The engineers also described what the upcoming security system would be when they take off the passwords. They also said that the firm is currently considering YubiKey which looks like extra-small USB drives.

"We'd like your smartphone or smartcard-embedded finger ring to authorise a new computer via a tap on the computer, even in situations in which your phone might be without cellular connectivity," said the team.

"One option uses a tiny USB key called a YubiKey. When the user plugs the key into a latop, they are automatically logged into all of their Google accounts - without ever having to type in a password," they added.

The paper also talked about the users' difficulty in remembering passwords of various online services.

"Another option uses a 'smartcard-embedded finger ring to authorise a new computer via a tap on the computer," said the team..

They further said, "Although we recognise that our initiative will likewise remain speculative until we've proven large scale acceptance, we're eager to test it with other websites."
