How to create a custom user authentication in Meteor? - authentication

Question

I am trying to create the following authentication for an app:
User enters phone number and receives an SMS with a code generated in the server (the SMS is handled through an external service). If the user enters the right code he is logged in.
This means I must have two login stages: registering user with a phone and logging him in with the code, so this is what I think the client should look like:
Meteor.getSmsCode = function(phone, username, callback) {
Accounts.callLoginMethod({
methodName: 'getsmscode',
methodArguments: [{
getsmscode: true,
phone: phone,
username: username
}],
userCallback: callback
});
};
Meteor.loginWithCode = function(phone, code, callback) {
Accounts.callLoginMethod({
methodName: 'login',
methodArguments: [{
hascode: true,
phone: phone,
code: code
}],
userCallback: callback
});
};
But I am confused about the server side - there should be two methods:
the first should only register a user (and communicate with the SMS service) and second should log him in.
This is the server test code for now:
Meteor.users.insert({phone: '123456789', code: '123', username:'ilyo'});
Accounts.registerLoginHandler(function(loginRequest) {
var user = Meteor.users.findOne({phone: loginRequest.phone});
if(user.code !== loginRequest.code) {
return null;
}
var stampedToken = Accounts._generateStampedLoginToken();
var hashStampedToken = Accounts._hashStampedToken(stampedToken);
Meteor.users.update(userId,
{$push: {'services.resume.loginTokens': hashStampedToken}}
);
return {
id: user._id,
token: stampedToken.token
};
});
And this is what happens when I try it:
Why an I getting the 500?
Why doesn't the user have a code and phone fields?
What method should I use for the getSmsCode?

Answer 1

Meteor.createUser is described on How can I create users server side in Meteor?
Then, the Accounts.onCreateUser would contain business logic http://docs.meteor.com/#accounts_oncreateuser
A more exact message for the 500 would be on the server-side stdout. Probably security.

Answer 2

Your Login Handler must return an object as follows:
{ userId: user._id }
Sorry I don't elaborate in the whole problem, I don't agree on your full approach but looks you are in the right path to get the feature you need.
Also, this question is one year old, now there are a few packages at atmosphere that address this kind of authentication =)
