Can I set a password for intercepted text messages and phone calls?

Some mobile phones have this function.

A mobile phone belongs to a mobile terminal and can be held in your hand. In the early days, it was commonly called mobile phone because of its large size, and now it has developed into the 5G era. 1973 in April, American engineer marty cooper invented the world's first civil mobile phone, and marty cooper was called "the father of modern mobile phones" from now on. Today, mobile phones have become a very important tool in people's lives, and their functions are as diverse as Swiss army knives, bringing people a wonderful life experience.
