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".
