Today, we’re announcing a new feature for developers called WordPress.com Connect, a secure and easy way for millions of WordPress.com users to log in to your website or app.
For WordPress.com users
Using the same log-in credentials you use for WordPress.com, you’ll now be able to sign in to third party sites that integrate with WordPress.com Connect. From your WordPress.com dashboard, you can easily control which apps have access to your data and remove access to those you no longer use.
