Can one email join two academies?
In short
Yes, one email can have a separate account in each academy, with its own password and courses.
Separate accounts
The same email gets a separate account in each academy, with its own profile, role and purchases.
Separate passwords
A password from one academy does not work in another.
Google sign-in
A Google account can belong to only one academy, the first one it signs in to. In another academy the page says to log in with email and password.
Private by design
You only ever see your own learners, and the sign-in page never says which other academy an account belongs to.
Good to know
A learner who sees "This account cannot sign in to this academy" has no account here yet. Check the address they use, or invite them.
Courses and purchases never carry over between academies.
