I would like to log into my todoist account using my google account on android, but I can't. Can you please fix it?
Our brand new Android app which will be released in 2 weeks will have such option, but for now, in order to log into a mobile app, you'll need to set a separate password for your Todoist account.
To do so, go to Preferences (upper right corner) -> Account and use the "Edit" link in the "Password" section.
You will still be able to log in with one click to the web-app using your Google Account, but if you're using a mobile app, please enter your GMail address in combination with the newly set password.
