I'd like some help with Identity please. Home Here the user registration is by Branch, I customized the ApplicationUser by putting the field FilialID and the field in the AspNetUsers table, but now at the time of login it would have to be verified username , password and branch because I have, for example, user "eduardo" at branch "01" and user "eduardo" at branch "02". Home The Branch I get by parameter in querystring , and the login screen continues only with the UserName and Password fields. Can you do that? Where do I start? Thanks in advance for your help.
