Standard Authentication on Several Devices
Over the last years, it became increasingly common to use multiple devices at the same time. No matter if you have used a computer, a smartphone, a tablet, a smart-watch or another intelligent device, you generally had to login to each and every device before you were able to start working with them. As a consequence, you had to authenticate yourself on each device separately with username or e-mail and password. This exercise was annoying, not user-friendly and always wasted time.
