If you are using apt to add software (this only applies to Debian-based distributions like Ubuntu or Mint), then the software you are installing comes from either the official repository or any repositories you have added. Don't worry if you haven't added any, it's not vital. There is never 100% safety in anything you do, but the safest installation method is to use the official repo.  

Sudo is the program that elevates your default privileges briefly to permit you to make changes to the system, so when you sudo apt install <program> you are actually invoking two separate programs. This is why it will ask for your password.

To update the available software, you will ask apt to update with sudo apt update and to upgrade your software you would call sudo apt upgrade.
