MVC5 Identity + Multiple Context in EntityFramework

I have an MVC 5 application that uses default authentication. The user profile is part of our model, which means there are several classes that have a foreign key to UserInfo. There are 2 DbContext, one for the model and one for the UserInfo.

 public class ApplicationDbContext : IdentityDbContext<UserInfo>
    {
        public ApplicationDbContext()
            : base("Profile")
        {
        }

    }



 public class UserInfo : IdentityUser
        {
            public UserInfo ()
            {
                LibraryItems = new List<LibraryItem>();
                if (UserGroup == UserGroupEnum.ANALYST)
                {
                    Companies = new List<Company>();
                }
                DateCreate = DateTime.Now;
                DateUpdate = DateTime.Now;
                DateDelete = DateTime.Now;
            }

            [DisplayColumnInIndex]
            [DisplayName("Is Active ?")]
            public bool IsActive { get; set; }

            [Timestamp]
            public byte[] RowVersion { get; set; }

            //[ValidateFile(ErrorMessage = "Please select a PNG image smaller than 1MB")]
            //[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:MM/dd/yyyy}")]
            [Editable(false, AllowInitialValue = true)]
            public DateTime DateCreate { get; set; }

            //[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:MM/dd/yyyy}")]
            public DateTime DateUpdate { get; set; }

            //[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:MM/dd/yyyy}")]
            public DateTime DateDelete { get; set; }

            [DisplayColumnInIndex]
            public String Name { get; set; }
            [DisplayColumnInIndex]
            public String FirstName { get; set; }

            [DisplayColumnInIndex]
            public String Pseudo { get; set; }

            [DisplayColumnInIndex]
            public string PhoneNumber { get; set; }

            [DisplayColumnInIndex]
            public String Company { get; set; }

            [DisplayName("Name_Id")]
            [ForeignKey("FullName")]
            public int? NameId { get; set; }
            [DisplayColumnInIndex]
            public UserGroupEnum UserGroup { get; set; }

            [DisplayColumnInIndex]
            public UserStatusEnum UserStatus { get; set; }

            public virtual Name FullName { get; set; }
    }


public class Comment
{
       // more properties
        [DisplayName("UserInfoId")]
        [ForeignKey("UserInfo")]
        public virtual String UserInfoId { get; set; }
}

public class Like
{
      // more properties
        [DisplayName("UserInfoId")]
        [ForeignKey("UserInfo")]
        public virtual String UserInfoId { get; set; }
}

      

        
        
        
      

    

My userInfo also has foreign keys to other tables in the second DBontext.

What is the best way to design our authentication system? and maintain a link between the two contexts.

Thanks in advance.
