iTunes ask for an Encrypt local backup password when I've never used it before
Hello, I try to use 2 iphones in itunes for first time but keep asking me for Encrypt local backup password. I never use a password, I have tried to uncheck de box but ask for password, I try several ones but not working. Why itunes ask for passwords if I never did a backup on my computer? And I also can not use other programs with my iphones because ask for itunes backup password, which I dont have because I never did a backup on this pc, thank you.
