The keyboard on my son's Samsung tablet has become disabled, how do we fix this?

[Android Central Question]

He has a password to gain entry but without the keyboard cannot enter it so as to have access to settings etc..
How do we override this?

Welcome to Android Central! If you're stuck at the password entry screen without a keyboard showing up, you could try using a basic USB keyboard connected via OTG cable.
