Thanks for an excellent question.
Yes, that particular video is a bit outdated now. We'll be updating it soon.
Starting with s2Member v3.5+, PayPal® API Credentials were consolidated into s2Member's core PayPal® processing routines that come with the free version of s2Member. In addition, PayPal® Button Encryption was added to the free version, which requires API Credentials. Otherwise, at this time ( i.e. v3.5.7 ), that is the only reason API Credentials would be needed.
In other words, if you're using the free version, and you're not encrypting your PayPal Buttons, you can just leave the API Credentials empty if you need to. We'll be updating this panel in the next release to make this clearer. ~ Thanks for your patience.
