Password
Option One: Tablet Password
If your tablet has a password, it is made of two parts:
A: either "tab" or "tablet"; and
B: the last three or four digits of the serial number.
So, if your tablet label has, for example:
TECHB1H5100051 CMIT ID 2019AP8640
Try the following:
tab051
tab0051
tablet051
tablet0051
tab640
tab0640
tablet640
tablet0640
Option Two: Power Off
If you completely power down the tablet by holding the power switch button for probably 10 seconds or more, then turn it back on, it should not ask for a password.
