So I would like to get a VPN going, but I cannot put in the credentials because of a password, which I don't know because I never set it. I tried to check out other people's forum posts, but all they say is to press the Delete All Credentials option, which I cannot do because it is grayed out. I also tried to remove my screen lock but that didn't work. I thought it might have been AVG security options, but I disabled administration and nothing happened. Just a heads up on what I have on my phone, I have a custom phone locker and launcher, developer options enabled, a mobile meter (which I'm trying to set up the VPN for), and a bunch of games and apps and such that don't impact system settings (other than notifications). Help would be great.
