In the context of usable security (related to computer science), a major challenge is to provide security means in such a way that all of the people including those with some disabilities (e.g., blindness and deafness) be able to use information systems. So, in some cases we need to refer to these two general group of users. The question is how to do so in a respectful way. For example, referring them as ordinary and disabled users is a bit harsh.
Also, I don't like using "disabled users and users without any type of disabilities" to refer them.
What's the best way to describe these two group of users? Shorter options are preferred!
