where on earth, why should this be a good idea?
Everwhere and all the time we've been told to have a unique emailaddress and password for each application we log in to, for safety reasons. This ist still the right way to keep abuse away. If you force us to change to a social media account for credentials, our private routing data will be on risk to get unfolded to thirdparties without our knowledge and without our consent.
And it is not only our routing data which is disclosed, it is also the information where we have been and where we like to go, at what date and time we spend our time in developping routes and whenever we're riding. This is information others have to keep their fingers off.
When you like to get it working with social media account, you can read something like this:
Mit der Einrichtung von „Mit Apple anmelden“ können Informationen zu deinen Interaktionen mit Apple und zu diesem Gerät von Apple verwendet werden, um Betrug zu verhindern.
Google sounds like this:
Wenn Sie fortfahren möchten, müssen Sie zustimmen, dass Google Ihren Namen, Ihre E-Mail-Adresse, Ihre Spracheinstellung und Ihr Profilbild an myrouteapp.com weiter gibt. Bevor Sie myrouteapp.com verwenden, können Sie die Datenschutzerklärung und die Nutzungsbedingungen lesen, die dafür gelten.
This is a lovely aim, but any interaction is analyzed before and it's not mentioned that this interactions are related to the use of MyRoute. By the way, if your socialmedia account ist leaked, all your apps are too!!! So, you've no access but you've still to pay for them, because you can't change your credentials in an easy way.
Thanks a bomb!
