Survey: when registering on a site / mobile application, what is more convenient for you to enter as a login?

    Hello, Habr!

    A dispute arose with colleagues about authorization on a site / application convenient for most users.
    Briefly about the abstract service - let it be a cross between Skype, Viber and WhatsApp. The ability to make calls through the service and to mobile, send messages via SMS and chat.

    You need to understand that a phone number is not required, but is necessary for the full use of the service. Of course, it will not be transferred to third parties, used for spam mailings and so on and so forth.

    Participation in voting and any comments on the topic are welcome.

    Only registered users can participate in the survey. Please come in.
