Troubles with password
I don't remember my iPhone 5s password, and I can't reset it using iTunes. What to do? my iPhone is disabled and asks to connect to iTunes
iPhone 5s, iOS 11
FYI, there is an iPhone passcode and an Apple ID password. I assume you mean passcode. If so, these are your only options:
If you forgot the passcode on your iPhone, or your iPhone is disabled - Apple Support
If you still have problems, see the "Still need help?" section in the above link.
