Add download links to user account panel after payment!

Hello

I have few questions, please advice

1- lets say a user order a product like video course from my wordpess/ woocomerce website, any idea how to add this video info user account panel?

2- what you think about add that video in a post, and secure the post with password and send it to the client via email? is that going to work?

3- any chance to prevent user to not share his account login and post password ( Number 2 ) to the others?

Regards
