update login

i receive the following error when I start index.js

node:13972) DeprecationWarning: open() is deprecated in mongoose >= 4.11.0, use openUri() instead, or set the useMongoClient option if using connect() or createConnection(). See http://mongoosejs.com/docs/connections.html#use-mongo-client
Db.prototype.authenticate method will no longer be available in the next major release 3.x as MongoDB 3.6 will only allow auth against users in the admin db and will no longer allow multiple credentials on a socket. Please authenticate using
MongoClient.connect with auth credentials.

Hi I have updated the code and you should not see the warning anymore.
