Can I publish an app that requiers an account on a webpage?

Question

I have a webservice that requiers accounts. As a complement I have built an app that can be used with the account on the website.

Do I have to provide the possibility to create an account through the app or is it enough to reference to the website?

Answer 1

If you have to be registered to use the application, you must allow:

• users to register in the app
• users to log in in the app
• allow the users to use the application without any account (maybe with less functionnalities).

If not, the app may be rejected.

Answer 2

there's no Google enforced practices of banning app or anything like this. You can release your app however you prefer.

But be warned that apps with a Login button, but if you want to Sign up you have to go to the web are usually not very successful apps and have very poor ratings on the Google Play.
