I would like to edit the Luks passphrase prompt on the Plymouth screen

I would like to learn where I could edit the prompt that Plymouth gives during boot, asking for the passphrase to unlock my encrypted partitions. It may have been a bug, but openSUSE 42.1 had only the empty box with no prompt. In 42.2 there is a large text prompt for me to enter the passphrase. I would like to either change the default text, or possibly just remove the prompt all-together.
I have been unable to find the location in order to edit it. Can anyone chime in please?

This should help on changing it…

That thread showed how to change the password. I am wanting to change or remove the prompt that asks for the password, not the password itself.
