'As' is more for the format, not a specific value. For example, enter your name as all capitals with no punctuation. So Casey Oda would be entered as CASEYODA
#2 works for me. I think it is what I would usually say.

Unfortunately, the OP has given us no context whatsoever.
We don't know whether the program is providing the password for the user or trying to give an example of how to enter whatever password has been assigned.
Either way, the possible ambiguity of including the quote marks in the field is a problem.
