Emailtoid is a free mapping service that allows email addresses to be used as OpenID identifiers. Per their website, Emailtoid explains that one critical criticisms of the use of OpenID’s usability is that users sometimes do not feel comfortable relying on the URLs for identifiers, and feel more at ease using their own personal email addresses to identify themselves.
As a solution to this issue, the web-based Emailtoid tool converts email addresses into fully functioning OpenID URLs. Since there is no need for passwords, this seamless tool is made to be a quick, simple, and powerful solution.
EmailtoId.net In Their Own Words
“Emailtoid is intended as a temporary solution to a usability problem in OpenID. If you run an email service and wish to resolve OpenIDs on behalf of your members, we have designed Emailtoid to always defer to email providers first, and then to fallback to our local resolution service if the email provider does not support email-to-OpenID resolution.”
Why EmailtoId.net It Might Be A Killer
Emailtoid is a simple and powerful solution for creating OpenID URLs. It is a personalized and simple tool, and easy to set up and use. Yet although there may be users that are in fact partial to identifying themselves with their personal email address, there may be others who are hesitant about putting it out in the open. Security should be blatantly discussed to ensure users of their privacy.
