Linking a Microsoft account to your existing Tiller subscription
Use these steps if you first signed up for Tiller using a Google account and you're having trouble signing in to Tiller for Excel because you get a "browser or app may not be secure" error message.
Navigate to https://my.tillerhq.com/dashboard/settings and choose the Google login option
Click the “link” button in the upper right above your primary identity
Choose the Microsoft option
Enter the username and password for the Microsoft account to sign in (or select the appropriate account if it's already signed in)
After successful sign in you’ll see the new identity is linked to your subscription. If you get an error that the identity is already in use see these troubleshooting steps.
Now when you try to sign in to Tiller via the Excel add-in choose the Continue with Microsoft Account option and sign in using the account you just linked at step 4.
ℹ️ Please note that linking another identity does not change the primary account associated with your Tiller subscription. There is not a way to change the email address associated with your account. To receive the daily email summary at a different email or change your primary sign in identity you will need to start fresh in a new account.
I'm seeing an error that identity is already in use
Use the chat tool in the lower right corner of this page to send us a message and choose "something else" and let us know what email address you are trying to use as a secondary identity that is showing this error that it's already in use.
I'm seeing a Microsoft account doesn't exist error
The account linking for Microsoft accounts does not work for school or business/work accounts because these are not Microsoft Live accounts. They are Microsoft Online accounts and a different URL is used to login to these accounts.
Link a free personal Microsoft account or create a new one at https://signup.live.com/signup and use it to link to Tiller as a secondary identity
