Your Newton account is how you sign in to Newton. Your email accounts, such as Gmail, Outlook or iCloud, are the mailboxes you add to it. One Newton account can hold many email accounts, and they appear on every device where you sign in.
How it works
Your Newton account is your login. You sign in with an email address and password, or with Google, Microsoft or Apple. On phones, Apple sign-in is available on iPhone and iPad.
Your email accounts are the mailboxes Newton shows you. You add them after you sign in, and you can add more at any time.
Signing up with Google or Microsoft creates your Newton account and adds that mailbox in one step. Signing up with Apple or an email address creates only the Newton account, and Newton then asks you to Select your email provider.
Signing in with Google or Microsoft on a computer or at account.newtonhq.com only signs you in. It doesn't add a mailbox.
On iPhone, iPad and Android, the Google and Microsoft buttons sign you in and connect that mailbox at the same time.
Good to know
Sign in the same way each time. If you choose a different Google, Microsoft or Apple account, Newton creates a new, empty Newton account.
If your Newton account uses Google, Microsoft or Apple, it has no password. Signing in with an email and password shows "This account uses Google, Microsoft or Apple Sign-In." Use that button instead.
To sign in with a different address, go to account.newtonhq.com › Profile › ••• › Change Login Email. You can pick any email account you've connected.
Removing an email account doesn't delete your Newton account, and logging out doesn't remove your email accounts.
