You can copy the login form in an external file, setting user & password default values.
Use JQuery for submit button emulation.
To help you to find a way, I attach 2 html samples (depend on your LS version):
Just adapt:
YOURDOMAIN
USERNAME
PASSWORD
No need to upload; can work from your desktop if the 'action' url value is correct...
If you have to use some differents sets admin+password, just change it for php file and set variables.
