If we run the backend to verify credentials without waiting for it to
finish, the redirect might happen before we know if the credentials are
invalid, unverified or verified - which will cause us to give the wrong
information to the user.
Yes, this additional wait is annoying, but I can't come up with a better
way to do this and avoid incorrect information. At least the UI isn't hung
while we wait.
