Is there any research available about the viability and use of "Remember Me" toggles/check boxes on login flows? I can't seem to find any information on whether or not they're used or not.
I did a super-informal hallway study about a week ago. So, obviously not something to cite, but may give you some ideas for your own study.
I asked 10 people if they found the 'remember me' feature useful in the context of a secure mobile app (context is likely key here).
7 out of 10 said they rarely use it namely because they forget to check it before they log in most of the time.
5 out of 10 said that when they need to remember a login, they use 3rd party password management software to handle it for them (like 1Password or the web browser itself).
My personal opinion: They don't hurt, but likely don't help as much as we think they do. I personally fall into that group of 7 in that I usually time in my credentials, hit submit, THEN see the 'remember me' checkbox too late.
I couldn't find any paper written on this subject. Perhaps you could start by looking at the following websites:
Good luck, Antonio
