When attempting to connect and entering a password into the Password field, with certain initial characters, the password field will fill and that initial character cannot be typed as part of the password.

Example:

User types "b" into the Password field.

The password field displays: ••••••••••••

The user then types "a", and the Password field displays: •

The user cannot type the rest of the password "badminton" because "b" causes the autocomplete to occur. "a" causes the password field to clear and is accepted as the first character of a new password.

This behavior occurs with numerous characters for me: b, e, w, A, C, H, K, P. I have just verified that these all correspond with stored values for the Username field. It appears that Cyberduck is attempting to auto-complete the password field based on valid values for the username field.

-WORKAROUND:*

Typing the password elsewhere such as TextEdit, then cutting and pasting into Cyberduck's password field will allow entry of the correct password.
