Login for hookups app
I'm developing an android app for hook ups with strangers, I understand that Facebook/Twitter login are not appropriate, but between security and flexibility, I'm confused how to register new users, I have the following options:
- Google account login (Super easy for Android users, but maybe users do not want to link the ap to his account [thought: I can show message that says their profile will be separate from Google+ activities])
- Phone Number (not as straightforward, and users might not want to, but will give me good identity confirmation)
- Email (No security and not very good flow, but an option nonetheless)
Which one [or multiple] do I pick, this is an MVP and looking for a point to start from
