[All Platforms][Developer] An Spotify internal, passwordless authentification

[fefeblabla]

If you install spotify on a new device,

like on an PC, you have to authentificate yourself with your Spotify E-Mail/Password or an third party service.

Due to my experience with IT, I know it's possible to create an secure and passwordless authentification system.

Something like an QR-Code or an OTP/Token/Secret for fast and secure Authentification, makes the need for an password trivial.

With the right execution, it could lead to an over all better user-experience.

We are all lazy and don't want to remember passwords! ^^

=> I've seen you implemented an feature to authentificate via E-Mail.. it's close to what I ment and it could be an little easier..
