Created attachment 145708 [details] KDE Online Accounts check up SUMMARY STEPS TO REPRODUCE 1. add a "google" account 2. go to google security check up 3. OBSERVED RESULT You can read that KDE Online Accounts access has not been validated by Google. See the joint capture. EXPECTED RESULT You can read there is no access problem. SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: 5.23.5 KDE Frameworks Version: 5.23.5 Qt Version: 5.15.2 ADDITIONAL INFORMATION kde gears 21.12.
It's up to Google to validate us. However the real story here is that Google is trying to scare people who use 3rd-party tools as a way of encouraging them to use Google's own apps.
Ok but you can see in the capture that "Akonadi resources for G service" and "digikam" have been validated. I fear your explanation is not good. If I opened this bug report, it is because I fear getting some problem accessing to my G drive using kio gdrive which uses kaccounts.
