I tried to jailbreak my iPhone but I didn't know it couldn't have a password?

I'm on ios 7.1.2 and I used pangu to jailbreak my iPhone and I had a password but I didn't know I couldn't have a password so I tried it again but it didn't let me and I don't know what to do now but I really want to jailbreak my phone, someone help!

If you really want the password, do not jailbreak with pangu
