How Movable Type 3.0 will authenticate?
TypeKey helps ensure that people who comment on a site have a verified identity, keeping conversations on track and helping to prevent abusive or offensive content (comment spam) from being posted. Sites that enable TypeKey have better accountability for the content that's being published.
As a TypeKey user, you get your own free TypeKey Profile Page, displaying only the information you choose to share. Those who are interested in finding out more about the person behind the comments on a site can visit the identity page to see what information is publicly available. You can even publish a TypeKey Profile Page while remaining completely anonymous.
…Who runs TypeKey? Is it safe?
TypeKey is a service of Six Apart. We're a well-established weblog software company, with hundreds of thousands of users and offices in the U.S. and Japan. We're committed to making sure TypeKey is reliable, safe, and secure, and we've made sure our privacy policy is as protective as you'd expect: We don't want to send junk mail to you any more than you want to receive it.
TypeKey never shares your password information with site owners, and comment information is only retained on the site you've commented on, not on the TypeKey service. TypeKey is a service for authentication and, in the case of comment registration, we leave it up to the weblog owners to decide who can post to their own weblogs.
