The X80 won't except password ,need to reset

Unfortunately if Factory Reset Protection is enabled, there is no way of formatting the phone unless the right credentials are input. Check that your account IS the one set up for the FRP.

You can't reset it without the existing password for verification. If you at least remember your Google login info, you could factory reset the entire phone. That does mean you'll have to start over from scratch, but it's the only way to remove the lock screen password. If you don't remember your Google account info, then even that won't work because you'll need that for verification to setup the phone again.
