The Ethereum Wildfire Project is promoting the use of Ethereum for general-purpose authentication. On our website, https://ethereumwildfire.org, we have a demo of how MetaMask can be used to login to a web service. We are also going to popularize Ethereum-based authentication techniques for corporate settings, for example, logging in to your company’s intranet. EWP is in a seed-funding phase. We are only raising a maximum of 4,000 ETH.
