i want to know can i use a list of domains separated by comma or array in place of 'school.edu' is there any simple tutorial for meteor accounts system ? pls help

Answer 1

restrictCreationByEmailDomain String Or Function

If set, only allow new users with an email in the specified domain or if the predicate function returns true. Works with password-based sign-in and external services that expose email addresses (Google, Facebook, GitHub).

Accounts.config({
  restrictCreationByEmailDomain: function(email) {
    var domain = email.slice(email.lastIndexOf("@")+1); // or regex
    var allowed = ["school.edu", "school.edu.br"];
    return _.contains(allowed, domain);
  },
  ...
});
