Meteor custom login procedure - meteor

Question

This Meteor app has the insecure and autopublish removed and accounts-ui accounts-password added.
The code below needs to get the username and password, send them the to server which will run a method validateUser that returns true if valid.
validateUser tries to login to another server on the web, and returns true if successful, then my code should create a user account for this user.
The app is crashing because of this line
Accounts.createUser(useername: digest[0], password: digest[1]);
But even if it does not, Is this the meteor way to get this particular task done? Thanks
Edit:
After adding {} to the problem line in order to pass an object as suggested in the comments, I now get this error printed in the terminal;
Exception while invoking method 'logMeIn' Error: Match error: Failed Match.OneOf or Match.Optional validation in field password
<template name="myLogin">
<input type="text" name="username">
<input type="text" name="password">
<button id="logMe">log me in</button>
</template>
Template.myLogin.events({
'click #logMe': function() {
var credentials = [$('#password').val(), $('#username').val()];
Meteor.call('logMeIn', credentials, function(err, result) {
if (result) {
console.log('logged in!');
}
});
}
});
// on the server
Meteor.methods({
logMeIn: function(credenticals) {
//do work , if logged in, do next line
console.log("user account created");
Accounts.createUser({useername: credenticals[0], password: credenticals[1]});
}
});

Answer 1

Match error: Failed Match.OneOf - is because this method checks if email or username is presented in the object you are passing. You have typo in username and don't have email.
Next thing you are saying, after fixing typo you get Exception while invoking method 'logMeIn' Error: Match error: Expected string, got object in field username
This is because you have array with two undefined "members". Look at your jquery selectors. You are trying to select by id # but have inputs without ids.
Please organise yourself.

Answer 2

Your line
Accounts.createUser({useername: credenticals[0], password: credenticals[1]});
Has two typos, it should be
Accounts.createUser({username: credentials[0], password: credentials[1]});
