For tracking your points, the service you're looking for is AwardWallet (no endors*m*nt). It's apparently the only service that is able to display the point balance of various difference awards accounts automatically. Notably, it doesn't support a few major services, like United MileagePlus, but it does support Emirates, and it's the closest I think you'll get.
As far as remembering loyalty numbers, I would recommend to first of all using a password manager like 1Password. 1Password can easily store such things and recall them in your browser using a browser extension. Plus it's a great habit for passwords as well.
