How do I send bestcrypt through email without sending username and password

Hallo!
First, I would like to say that bestcrypt is such a super software for encrypting data. Is there bestcrypt 5 version in the market? I would like a sincere opinion on what features it brings in over and above the lower versions. Normally when I send a bestcrypt container, the other person cannot access it because I have to send the password as well. Is there a way to send a bestcrypt 5 container without having to send the username and password as well?
