IHello my daughter accidentally locked her phone by forgetting her password is there a way to reset it without a computer

Maybe. See the first link: If your iPhone has iOS 15.2 or later installed, check out this link→How to reset your iPhone, iPad, or iPod touch when you forgot your passcode - Apple Support. Otherwise you will need a computer:

See this Apple support link→If you forgot the passcode on your iPhone, or your iPhone is disabled - Apple Support

Or watch this companion video ⬇️

After restoring the phone using one of the methods above you can restore your most recent backup.

If she is running iOS 15.2 or later there will be an option to erase iPhone on the Home Screen. Otherwise, you'll need to connect to a computer to reset the device.
