Nit: Could you reword this to make it more explicit that this needs to be called
from the outside? The sentence is correct as-is but I have seen many places
where people confused "call" and "called" in comments. Making it more explicit
will ensure that the sentence is not misunderstood by anyone. How about
something like:

// Call this method when the user signs in to a GAIA account.
