I've tried both a manually typed password after a reset,
AND having Apple keychain remember what my changed password is
and in both cases, after a half-dozen tries,
when I log out, and then attempt to log back in
either manually typing my password
or letting Keychain re-enter what it captured when I reset the password
Portable Apps will not let me in.
Not on my Mac, not on a separate PC.
So it seems it's actually NOT changing the password? or there's an error in what PortableApps actually ingests as the password, because once I go through the Change Password process, I can't log in with the new, changed password from my Mac or a separate PC.
