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?
No. A work must meet the criterion of "originality" to be copyrightable:<p>"Creative work must meet a basic level of originality to be considered the product of an author. Direct copies of someone else’s work can’t be copyrighted, and neither can facts, <i>short phrases</i>, titles, etc. For example, the names and addresses in a phonebook can’t be copyrighted but the photo on its front cover most certainly can."<p><a href="https://www.newmediarights.org/business_models/artist/ii_what_can_and_can%E2%80%99t_be_copyrighted" rel="nofollow">https://www.newmediarights.org/business_models/artist/ii_wha...</a><p>Also, even if you <i>could</i> copyright your password, copyright protects against unauthorized distribution. If Google is merely storing your password, it's not distributing it.<p>(A single word or phrase, e.g., "Google", can be trademarked, but that specifically involves its use in commerce to identify a brand. But it can't be copyrighted.)
