I tried starting VPN, didn't set password, but later now screen is asking password. What to do? I have Gionee P5L phone. I was not able to access a site, then thought on starting VPN of the phone; went to VPN, and then it asked to set any of the security: password, swipe, etc. I entered into password section, but didn't press any password, then pressed back button. Now, phone is asking password, but I didn't set any password before. 

I didn't really type any password, as I remember. Same thing had happened before with my other Gionee P5W; but then I tapped on forgot password, it asked me security question and allowed me in. Here, with P5L, on tapping forgot password, it says me on me to have not set any security question and the only option as to factory reset. 

What do I do to remove this password wall?
In order to enable built-in VPN, you must put a screen pattern or pin code, that's a security feature. 
So you did put a code, just remember
