Convert Anonymous to username/password

[Jesper Mansa]

Hi BrainCloud,

I am trying to figure out how to convert an Anonymous account to a user with username/password (not email/password) What api call should I use for this?

Also, how do I ensure that the same username is not used for multiple accounts?

Call AttachUniversalIdentity() method from client lib, the username is uniqueness enforced.
