You may be given access to multiple Hint accounts using a single email address. The first time you accept an invitation to Hint you will need to create your login which includes setting your first and last name and your password.
If you already have access to Hint and you're invited into a subsequent Hint account, you should click the invitation emailed to you and then choose the option 'Already have a Hint Health account? Login Here' as shown in the following screenshot:
After you've logged in, you might need to click the invitation link in your email again.
Once you have access to multiple Hint accounts you can toggle between multiple accounts in the upper left of your screen.
