Connect with Todoist App
How to login in the App when you signed on with your google account? Cannot signin for the app version
our new official app (which will be released this month) will support Google log in, but for now, in order to log into any existing app, you'll need to set a password for your Todoist account.
To do so, go to the Preferences -> Account tab and simply add a password using the "Edit" link in the "password" section. Note - you will still be able to log in with one click using your Google Account on the web-app, but just for the mobile app, you'll have to use your GMail address in combination with the newly set password.
