Some tricks could be played to make it more secure. One would be to scan
the message for the user's password and if it found it, but it didn't
seem to be part of an authenticator, bounce the message. It could also
use a fuzzy match for the authenticator, though it should bounce
messages which aren't perfect. There is also a trivial way to prevent
errors. Have a user config parameter which lets the user select inline
authentication or mailback authentication. If the password doesn't
match, the message will be bounced, not even submitted for mailback
authentication.
Even without any special coding, a message with an incorrectly formatted
inline authenticator would be mailed back for web authentication as
currently (unless by some stroke of luck you managed to mistype so
badly, you actually gave someone elses authenticator, but then it
wouldn't match your from header, and would be stripped in any case).
