I can see two ways:
1 - Use some virtual keyboard soluction. You can type your password with mouse-clicks, it will avoid keyboard logger (but may not avoid mouse-click based logger). However, it would be one level of security.
2 - You would just type a wrong password on the password box, select it with the mouse(replacing the wrong keys with the true), type the first 3 characters of the true password, type more 3 wrong keys, select the last 3 password valid keys (considering that the valid pass have 6 keys).
