I have an app that I only want my company's employees to use. It will be available in the Apple and Android App store. I am trying to figure out a way to secure it so that only the employees can log onto it.
Currently it is set up to accept a company email at registration and sends an email containing an activation link. I feel like there should be a better way of doing this that does not involve the use of email.
Does anyone have any suggestions?
Edit:
Also, this app is currently a prototype in the company, so I do not have access to employee ids and such as of now.
Don't put them in the stores. Google may allow it, but Apple at least is likely to reject an internal-only app.

For Android, you can just provide a .apk to download.
