Ask HN: Do I own the copyright on my logon/password
2 by Berniek | 1 comments on Hacker News.
Since I created the actual name of a logon and the password to go with it do I own their copyright? Do I own the copyright on my email address since I created (or selected) part of it? If so can Google (for instance) use it to create a token or other identifying or anonymizing artifact for their own purposes without my permission?
