Any chance to start WoW-client without entering a password?

[sharpMouse]

If I start WoW-client outside of the launcher, it requires to enter credentials.

Is there any way to start WoW-client already logged (like being started in launcher)?

The best solution should use minimum external software.

(The launcher starts WoW-client with command line arguments "-launcherlogin -uid wow_classic". But it doesn't work if I just add them to my WoW-client shortcut. I got the error "you were disconnected").
