Let readers login with their WordPress.com accounts
With WordPress.com Single Sign On, your users can log in to or register for your self-hosted WordPress site with the same account they use on WordPress.com.
This makes it easier on your commentators, users and subscribers by allowing them to use their current account with WordPress.com. They won’t have to create and remember a new login for your site.
Find and activate the Single Sign On module within Jetpack’s menu. “Once enabled, a “Log in with WordPress.com” option will be added to your existing log in form” (Jetpack).
You can configure this module further, if you’d like, by checking the boxes for it to also require an authentication code and/or match by email.
If you require users to have a two-step verification system in place, they’ll have to first sign in via their WordPress.com account, then input the code from their authentication app or text. For more on authentication accounts and setting one up, read this article.
