Changing the username will not break SSO.

SSO is never tied to the username, but to the external id and E-Mail address. If the external ID is not known to Discourse, it associates it with the account having the same E-Mail address (or creates a new one). Afterwards, any changes to the account won’t affect this invisible link, Discourse will always recognize the account by its ID.
