IMPORTANT: using this method of login poses a security risk. If you bookmark or store the link, other people could login into your account. Use at your own risk.

To login with a single URL, avoiding to have to type username and password, you can use this link:

http://www.server.com/desknow/home.do?Action=Login&username=joe&password=mypassword&encryption=plain

where www.server.com is the address of your server, joe is your username and mypassword is your password.
