Dolphin is currently investigating this issue. To work around the issue, the following steps may help:
1. Log into your Gmail account in a web browser.
2. Choose "Settings" (cog icon)
3. Choose "Security"
4. Next to "2 Step Verification - OFF" - turn this on.
Note: you will need to have access to the phone which you used to create your account in order to receive a security code.
You should now have an option available called "App Passwords". Choose "Create New" - give the app a descriptive name, for example GuideConnect, then enter a password that meets the criteria specified.
Once done, restart GuideConnect if already running and attempt to set up your Gmail account once more, entering the newly created password when prompted.
