Locked screen/password issue

While trying to set up a printer, I seemed to have changed my password. Now there is a screen lock and I am unable to get back into the system. Restarting also takes me to the locked screen.

Is there a way to get back into the system without flashing again?

We can only suggest to reflash the system.

You could clone first if there is content you won’t want to lose. Clone instructions differ depending on whether this is an SD card dev kit model, versus eMMC model.
