6. Click OK to create the encrypted archive file. The new archive file will be located in the same folder as the original file/folder.

Do not share a password via email. Passwords must be shared via out of band, meaning that you send the file and the password by different communication channels: one on the internet, and one not. The best way is to call the recipient of the Zip file and convey the password over the phone.
