1. How to generate the GUID

3. How/What to add data in the SecurityStamp column.

Answer 1

1. You can generate Guid with Guid.NewGuid().ToString()
2. You can use PasswordHasher int UserManager like this UserManager.PasswordHasher.HashPassword(password)
3. You insert any random string or a Guid.NewGuid().ToString() in SecurityStamp. It will automatically will be updated everytime user log-ins to system.
