User authentication with password created by Meteor

I am trying to authenticate user from server, using password created in Meteor by accounts-password and stored in DB. However passwords never match. What I am doing wrong?

    var bcrypt = require('bcryptjs');
    var crypto = require('crypto');
    var raw_pass = 'my_pass';
    var pass = crypto.createHash('sha256').update(raw_pass).digest('hex');              
    var encryptedPassword = bcrypt.hashSync(pass, bcrypt.genSaltSync(10));
    bcrypt.compare(doc.services.password.bcrypt, encryptedPassword, function(err, result) {
                if(result) {
                   console.log('OK');
                }
                else {
                   console.log(403);
                }
            });

The right way to check a plain password against a meteor generated one is by using sha256 and bcrypt as follows

var bcrypt = require('bcrypt')
var sha256 = require('sha256')
const samePassword = bcrypt.compareSync(
                        sha256(plainTextPassword),
                        user.services.password.bcrypt
                     )

Arguments for bcrypt.compare are 'plain string' and 'encrypted string'. So the right solution is:

var raw_pass = 'my_pass';
var pass-256 = crypto.createHash('sha256').update(raw_pass).digest('hex');              
bcrypt.compare(meteor.password, pass-256, function(err, result) {
            if(result) {
               console.log('OK');
            }
            else {
               console.log(403);
            }
        });

Account password doesn't use crypto for the password. It's only use bcrypt and salt to generate the encrypted password.

You can check compare password here

It would help us if you print out the output of bcrypt.compare. It might be returning 0, which would mean success, but in your if statement, 0 would be interpreted as false.
