Anti theft user interface...?

Hello. I selected my interface to be hidden.
But now I cannot remember how to pull it up on my phone.
I can’t get to the screen where it prompts you for a PIN.
Thanks.

Just “dial” your Avast PIN.

I would NEVER have thought to use the PHONE DIALER as an interface! Smart!
Thank you!!!
Huge help!
