Looking for maintainers. This plugin is currently not maintained. If you would like to take over the development please let me know using the plugin support forum or GitHub issue system.
WordPress Social Login is a good alternative to this plugin:
https://wordpress.org/plugins/wordpress-social-login/
Social Connect adds social login buttons on the login, register and comment forms of your WordPress site.
The buttons offer login and registration using a Twitter, Facebook, Google, Yahoo or WordPress.com account.
It makes it super easy for new members to register with your site and existing members to login.

Extends the Jetpack plugin and allows you to add a Vk.com sharing button to the list of sharing services available under Settings > Sharing in your dashboard.
Important: for this plugin to work, you must activate <a href="https://wordpress.org/plugins/jetpack/" rel="ugc">Jetpack</a> first, and activate the Sharing module.
If you find issues, you can report them <a href="https://wordpress.org/plugins/vk-sharing-jetpack/" rel="ugc">here</a>, or submit a pull request <a href="https://github.com/jeherve/vk-sharing-jetpack/" rel="nofollow ugc">on GitHub</a>.
Note: Once you’ve added the button under Settings > Sharing, it won’t appear on that page. Save your changes, and look at one of your posts to see the button in action.
