Screen Lock Message

Hey ya’ll. I’m running on Android 6.0.1 on a Moto G4 Plus.

I would just like to know why in Android:
Settings > Personal > Security > Screen lock

Why is it showing this message under “Pattern” “Pin” and “Password”:

“Because you’ve turned on an accessibility service, your device won’t use your screen lock to enhance data encryption.”

I have active the Avast Mobile Security and Avast Passwords accessibility services turned on. When I turn them off and go back to the Screen lock settings on Android, the message disappears.

You have answered your own question.

Okay… But can you please tell me what exactly that message means? I would appreciate it.

It means you have turned on an accessibility service.
And that is true as you say so yourself > “I have active the Avast Mobile Security and Avast Passwords accessibility services turned on.”
