If you’ve forgotten your iPhone 6’s passcode, there are a few things you can do to try and unlock it. First, try using the “Find My iPhone” feature to locate your phone if it’s turned on and connected to a Wi-Fi network. If that doesn’t work, you can try resetting your device by going to Settings -> General -> Reset and entering your passcode. If all else fails, you can contact Apple support for help unlocking your device. ..
