Giving one email is better so that they create under the same login for all your dependents and you can track in one login.
I explicitly asked to create one login but gave a different email for my spouse. They created 2 different logins.
you may get back the login credentials in a day or 2.
And copr, I see few are getting in a day or 2 and for few I see it’s taking a week or month.
And picture - not sure if we can use it. Mine is not beyond 6 months old. So, I uploaded it. But it should meet the specifications. If it matches and if it's less than 6 months old, i think you can use it.
