Google 2024 OAuth Updates

Google has announced that starting in the Summer of 2024, they will begin the process of moving fully to OAuth with third-party apps in order to better protect their users. This transition will disable access to less secure apps. Less secure apps being "non-Google apps that can access Google Accounts with a username and password (basic authentication)." As TDO Google Calendar sync already utilizes OAuth, existing TDO users would simply have to allow TDO Calendar access to their Google Calendar. New TDO users may have to enter their email and password in Google to allow access. 

For additional information regarding Google's update, please visit their article linked here - Google Help Center: Transition from less secure apps to OAuth.
