Can i use my iCloud login to reset my iPhone if i forget the Passcode?
I forget my passcode, I don't have an iso file to format my iPhone so can I log in to my iCloud on a PC and reset my iPhone from my iCloud.
If your iPhone has iOS 15.2 or later installed, see: How to reset your iPhone, iPad, or iPod touch when you forgot your passcode - Apple Support
If that option is not available, you will need to use a computer. See: If you forgot your iPhone passcode - Apple Support
