I run KDE/Plasma on Debian 11 and use PIM-Suite 'kontact' since a long time. My google-account is embedded via akonadi-agent google-groupware which performs well i.e. to have acces to calendar / dates / contacts. Well the contacts module in pim-kontact (kaddressbook) did not have my attention over the last time ... But now I state following behavior: WHEN I define in my google-account under security the 2-factor-authentification it seems to influence data-verification of my google-contacts within kaddressbook --> only a few contacts are shown. Stopping 2-factor-authentification leads to correct behavior = all my google- contacts are shown in kaddressbook. Is that an issue in akonadi-agent google-groupware ? Beware that 2-factor-auth. has no effect on google-calendar and google-lists
