On the right-hand side of the page, you will see "Account Details".
There, use the Edit button (pencil icon) next to the Primary Email.
Once you click edit, you will be asked to verify your password:
With that complete, you can enter the email you would like to use to access Ninety.
A confirmation code will be sent via email as the final step. This comes from firstname.lastname@example.org, so if you do not immediately see it please search your spam.
That's it! The next time you log in it can be with the new email you entered!
Remember, if you are using Social Sign In, via Google or Facebook, the Primary Email will need to match the account you are attempting to use!
