I am trying to find studies showing that users don't like to login and/or are not willing to get a login screen as the first screen of an application. I am waiting for analytics to push this idea and get 'rid off' of this pattern (first screen app is a login screen).
I am going to give you a little bit more of context:
I am talking about a mobile/web app being used on a tablet in physical stores by mostly 50+ users not really familiar with technology. We found a way to make the users login in a 'smart' but not as the first experience they will get about this app.
The marketing is trying to push hard the idea (and again...) that users should register/login first. - They want to (obviously) register new users and collect as much data as they can from them - ''If you are identified and/or authenticated we will provide you better services and push products that will fit your needs'' which is indeed a receivable argument.
However, I am afraid of the first impression users will get when they will see this first login screen in the app... 1- They will not be engaged at all with this app bearing in mind that users will play with this app in a shop and not at home... 2- Many users forget their credentials (still waiting for some web analytics to support that) 3- Security issues: If someone walks away from the screen and forget to log out or don't even know how to log out (a timeout won't solve everything). 4- I ve seen users during usability testings entering many fake credentials like 'email@example.com', etc...
My concern is to get a study, business case with stronger weight to put in the scale to support my findings and push back the marketing. I can't extrapolate that my 5-20 users are representative of their hundreds of thousands clients so I am trying to find a larger (quantitative) study or references to support my usability findings.
Would you please point me any good references?
