Authenticate Apptivo for Gmail sync

This is the most common problem that will cause an authentication error. After the first attempt at providing your username & password into Apptivo, you still may receive an error even if all information is correct. This is because Google has many different security protections in place to make sure no spam is sent from your email account.

After attempting to authenticate in Apptivo, you should receive an email from Google notifying you of possible unauthorized access to your account. This is 100% normal and expected. Now all you need to do is manually authenticate your account, by navigating to the Manual account unlocking page on the Google website. After submitting this page, you have 10 minutes to authenticate the account. Just go back to Apptivo, and re-try the same email/password, and you should successfully authenticate.
