Ok. When they need the code they will have to scan through a message like

    Do not share the code 3456

and will read the words, because they read left to right.

The code should be in the same font as the rest of the text.

I can assure you that by now, my brain is conditioned to lock into the four-digit code as soon as it can, entirely ignoring everything around it, including the words to the left.

I’m an avid reader. But there are limits to what I can process, and our world has become so full of noise that it has become a coping strategy for brains to selectively ignore stuff if they feel it’s not important at the moment. That effect becomes even more pronounced as the brain deteriorates with age.

		I do not believe that receiving such a message you will not notice the phrase. And more so if you receive them constantly. But of course, you are entitled to your opinion, even if it's wrong.
