I have an ionic app that I plan to push to iOS and Android app stores. A website currently exists where users can log in (giving them an access token).
Ideally I would like to achieve a user flow where logged in users on the website can click a link to install the iOS/android app, with their access token string being passed as a parameter to App Store/Google Play store so that once they open the app, the app can automatically log them in using their access token from the website.
 Is it possible to pass a parameter to the app stores and have access to this parameter on first launch?
 Is it secure (parameter sent over HTTPs) ?
