Question: I'm a programmer and often create login/register forms. I'd really like a single word to use to describe a form that lets the user login/register. Sort of like "authentication", but that's really more specific to the login part. The next best I can come up with is "onboarding", but that really applies more to the register part. Does such a word exist? Edit: I'm really looking for this from a coding perspective, not to display on the page (i.e. it doesn't need to be user-friendly). I just want it to be concise so that I can avoid variables like "login_register". 
Answer: This form is the single point of entry for new and existing users, so I suggest entry as an appropriate name for a single form for both login and registration. The name makes it clear it's the entry point. The only other name that springs to mind is account, but I think that would be better kept for something that allows you to change your email, password, settings etc.
yes

Question: I am just wondering about the difference between: in contrast to and in contrast with 
Answer: In fact, they could be used interchangeably, however, "in contrast with" is more common in UK English. Moreover, When we say "contrast with", CONTRAST is behaving as a verb. Example: "He likes to contrast his checkered jacket with plain pants" or "his checkered jacket contrasts with his plain pants." But when we say "in contrast to", it is behaving as a noun. Example: "His checkered jacket stands in contrast to his plain pants." (As you can see, in this sentence "stands" is the verb). (Testluv, GMAT Instructor, Beat the GMAT forum).
yes
