Sms/ email verification wp?

Question

WordPress

Is it possible to organize a way to verify certain actions on the site via sms / mail on wp? For example, I have a contact form cf7. before sending data from it, you need to receive a confirmation code that will come either via SMS or to your mail. Maybe there is a plugin?
ps After trying a few from the wp library and not getting the desired result, I decided to ask here.

Answer 1

Of course it is possible by hand. Too specific task

Answer 2

This is how
deobfuscation itself is simple, by the way.
1. First, we replace eval with an assignment to a variable and get a partially deobfuscated code (as @omun did as a result ) .
2. Further there in the code there is the same repeating combination:
s = String.fromCharCode(...); // as a result, the set of characters required to get the text of the function is output
(![] + [])[+[]][([![]] + {})...(); // get the text of the function from s and immediately execute it. We remove () and we can get the function code directly
