Samsunng Tab A6

[Ravenclaw22]

I  have a samsung EE Tab A6 that I can't get into because I forgot the password and google password. 

What is my best option to hand it back to EE and see if they can unlock it or just trade it in?

If you've forgotten the unlock code for an Android device, you may need to hard reset the device and lose the data on it.

@Ravenclaw22   The Google password will be what ever you’ve setup for Google, unless you have created new Google account since getting this tablet then it’s your current Google password. 

EE can not help you gain access to this device as they don’t know your password/passcode 

You can not trade in a device that you can not gain access to to use It.  It’s locked to your goggle account and that lock has to be removed in order to trade in.
