Password Protected Page – Text Change

I am wondering how to change the password protect text on a page on my WordPress site?

Currently the protected page displays: “This content is password protected. To view it please enter your password below:”

I have tried looking through my coding and found nothing to edit it! Does wordpress not allow for the text to be edited?

Help would be appreciated!

I am currently running the newest version of wordpress and I am using the Academica theme.
