Does having a space at the end constitute a valid password
e.g “ABCD ” or “ABCD12 “
Would it be fine, if we trim the password input (i.e “ABCD” would be the effective string after trimming) prior to authentication

I tend to trim “silently” almost everything the user types, as spaces are generally not shown in form elements.
But, for password fields, there is a ‘*’ or an equivalent — so even spaces are “visible” ; so you can’t trim the input silently.
Still, I would consider a password with a space at the beginning or end is not valid, and ask the user to modify it — but that’s probably a matter of personnal taste.
(Considering a user typing a space at the beginning or end of a password field is quite a rare situation, I would not indicate anything saying this is not allowed, though — until the user actually does that, of course : a registration form is already quite too complex for most users, so no need to say that kind of little/rare thing until it happens)
