Hello David and everyone,
That is we should suggest it. This should be a team effort. I'm sure
others often get frustrated by this limitation and should lend their voice to
encourage Apple to make such a feature available.

Peter,
I agree that being able to dictate passwords and PINs into secure entry fields
might be a nice idea. From Apple's perspective, however, they might feel that
this would make the secure entry field less secure. It might also mean some
serious modification of how voice dictation normally works. At the moment,
voice dictation is good for words and phrases. In other words, it's pretty good
when dictating phrases such as "I went to the store to buy some bananas."
However, passwords, at least good ones, aren't simple words. If you have a
strong password, that means you have a string of text, comprised of various
letters, numbers and other symbols, with letters being both lower and
uppercase. Suppose my password is ~Luv.,4BX7y Currently, there is no way to
accurately dictate such a string. It doesn't mean that Apple couldn't modify
the dictation service to accommodate such strings; I could see how this could
be done. It just means that the current implementation of voice dictation just
doesn't allow for passwords, particularly if those passwords aren't standard
words or phrases, which they really should not be. However, I don't mean to
suggest that what you're proposing is a bad idea. By all means you should
certainly suggest it.
