If your application wants a clear password, then you have to give it a clear password. There is no way around this.

You can have your password in your program in an encrypted form and only have it decrypted against another password it asks for when you run it. That would be a more secure way, but not really practical.

Another solution would be to save your password in a file on a memorystick and have your program read it from the stick and remove the stick once your are logged in. Then nobody can log in as you unless they also have access to the file on the memory stick. Your security problem then becomes a matter of physical security of your memorystick.
