User Management Tool compatible with EasyBlog

We plan to use Easy Blog. For AcyMailing we need the first name and the last name of the user. Is there a user management which is compatible with Easy Blog (Login, Avatar, social login), in which also "custom fields such as first name, last name can be used.

Or can EasyBlog the profiles also be adjusted according to their own fields and are compatible with AcyMailing.

Thanks
