An anonymous reader writes: Wired reports on a research paper from Google employees about the future of authentication on the web. 'Along with many in the industry, we feel passwords and simple bearer tokens such as cookies are no longer sufficient to keep users safe,' the authors write. Their plan involves authenticating just once, to a single device, and then using that to unlock all of your other accounts. "We’d like your smartphone or smartcard-embedded finger ring to authorize a new computer via a tap on the computer, even in situations in which your phone might be without cellular connectivity." Recognizing that this isn't something they can accomplish on their own, they've gone ahead and created a device-based authentication protocol that is 'independent of Google, requires no special software to work — aside from a web browser that supports the login standard — and which prevents web sites from using this technology to track users.'
