Forgot password on phone

I cannot imagine your precise question.

Perhaps it means:

• If you forgot your iPhone passcode - Apple Support
• How to remove Activation Lock - Apple Support
• If your iPhone, iPad, or iPod touch is lost or stolen - Apple Support

iPhones have passcodes. Apple IDs have passwords.

If you forgot your iPhone passcode, then the first bullet in my previous response applies.

You already marked this as "solved", so I guess you used that method and your issue is resolved.

Enjoy your Apple gear.
