One login for every company

1. Sign in with your email and password on any company's sign-in page or customer portal.
2. If your email belongs to more than one place (another company, or the customer portal), you see Where do you want to go?. Tap one.
3. If it belongs to just one place, you go straight there.
4. If you had different passwords in different places, the one you sign in with next becomes your password everywhere.
5. Changing or resetting your password changes it everywhere at once.

Each company keeps its own sign-in page, logo and portal, and nothing is merged or deleted. A placeholder email (like unknown@unknown.com) and an email shared by two different people can't get a login. Give each person their own email.
