We just ran across an instance where a customer using Sage 100 2020.x and paperless office for electronic delivery of statements was suddenly having their Google Workspace ( aka G-Suite or Gmail ) email account login and password rejected.
It’s important to note that this customer was NOT using two-factor authentication with Google. If they were to use two-factor this issue likely would have been resolved by using an app-specific password ( only available to those with two-factor enabled).
Just one month ago we thought we’d resolved this issue by enabling less secure applications within their Google email.
Google has begun tightening their security protocols for what they term less secure apps. Essentially these are apps which require you to enter in your Google credentials as opposed to using a more secure authentication which might grant access to only a portion of your Google account such as only email or only calendar access.
You can read more about Google’s less secure apps policy here.
It appears that while you can enable access for less secure apps, Google will periodically disable that access should the app not login for an undefined period of time.
This is apparently what was happening as our customer only printed statements every 30 days.
The resolution to the rejected login from within Sage 100 paperless office was to once again enable less secure apps from the Google account.
