Save PPTP VPN password

[Guest Time Sheep]

Hi there :)

I recently purchased a PPTP VPN, mostly for my computer, because I generally don't like that my school knows what I'm using the internet for. So I set it up on my laptop and it works just fine. Now I want it on my Desire too, but the problem is, that my password is a randomly generated one (12 characters, upper + lowercase letters and numbers) and it is not possible to change it at all. This password takes quite some time to type on my phone, so if there was a way to make the phone remember the password too, instead of only the username, that would be awesome.

Besides, if that is possible, is there also a way to make the phone establish connection to the VPN once WiFi is connected?
