Lumia 735 cant get past enter pin screen after accessing lock screen

[Windows Central Question]

Lumia 735 second screen asking to ENTER PIN I've never seen this before and don't have a pin for it? after 3 attempts it asks for you too enter a passphrase which is A1B2C3 to try again I can not get into my phone. It's not the lock screen, i've already accessed that.

Is there any chance of a picture of this screen?
