App verification function is blocking all my apps as well as "Settings" on my phone... very urgent

Hi

I clicked on the protect app function earlier by mistake and now Sophos demands a password every time I want to access not only most of my apps but also the "settings" function which would allow me to do a factory reset of my phone.

When I click on forgotten password, it asks for a recovery password which I don't have and a password which I don't have either. I am always very good at noting down passwords etc so would have done it when I installed this software. But I have no record of a password or of a recovery password.

What do I do as my phone is a real lifeline for me as I have disabilities and cannot function without it. 

I have a Mororola G.

This is really urgent.... Please help....

Many thanks

Anna
