If you type in something like "username = " and ask copilot to autocomplete it will follow its weights to find a username that in context has the highest value and then copy it. Unless a microsoft developer has manually gone into the software and written code to call a name generator for usernames and password generator for passwords, copilot will copy paste what it has in the training data. This was one of the many problems at launch since people did this for databases accounts, online accounts and so on. Copilot like all its similar created software can not create novel concepts. It can only copy and rearrange.
