Hello, I have an ASP application.I performed the tutorial on code first migrations. When I executed the commands, the following code was generated for the user table:

CreateTable(
            "dbo.AspNetUsers",
            c => new
                {
                    Id = c.String(nullable: false, maxLength: 128),
                    ApplicationId = c.Guid(nullable: false),    
                    Email = c.String(maxLength: 256),
                    EmailConfirmed = c.Boolean(nullable: false),
                    PasswordHash = c.String(),
                    SecurityStamp = c.String(),
                    PhoneNumber = c.String(),
                    PhoneNumberConfirmed = c.Boolean(nullable: false),
                    TwoFactorEnabled = c.Boolean(nullable: false),
                    LockoutEndDateUtc = c.DateTime(),
                    LockoutEnabled = c.Boolean(nullable: false),
                    AccessFailedCount = c.Int(nullable: true),
                    UserName = c.String(nullable: false, maxLength: 256),
                    Discriminator = c.String(),
                    LegacyPasswordHash = c.String(),
            })
            .PrimaryKey(t => t.Id)
            .Index(t => t.UserName, unique: true, name: "UserNameIndex");

My problem is that I don't need some columns. So, I removed the code from those columns and updated my DB. But, when I try to authenticate a user, I get this error:

Invalid column name 'EmailConfirmed'.
Invalid column name 'PhoneNumberConfirmed'.
Invalid column name 'TwoFactorEnabled'.
Invalid column name 'LockoutEndDateUtc'.
Invalid column name 'LockoutEnabled'.
Invalid column name 'AccessFailedCount'.

But these columns no longer exist because I deleted them. Or, is it possible to put it back and assign them default values ​​for example:

EmailConfirmed = false
PhoneNumberConfirmed = false

to avoid making an insertion when creating a user. I use EF 6.2.0

Need help please.
