Each user has one password, correct?

You only have one password for each user (which is per tenant) correct? A user can have different usernames, but only one password, right?

That is correct. Each user can have one email address, one username, or both. Either of these values can be used to login, and therefore the values are unique within the tenant.
We do have a username field on a registration, but it is not used for login.
