There are few obvious reasons for a prominent sign up buttons like,
- We need more signups
- We need the visitors to locate the sign up button quickly
- Most of the apps, dont sign out users after they leave the app. We are auto-signed in when we come back to that app. Like Facebook, google does.
But my concern is, what if I am using a different system or browser. In that case, it takes a moment to locate these login buttons/links.
Some apps(mobile and desktop), even have login as links that are difficult to click (with less touch area).
Doesnt Login buttons deserve better ? Atleast a ghost button like the below screenshot ?
