Enforce use of app specific passwords?

Hi all,

I am currently running nextcloud 11.0.0 and would like to know if there’s a possibility to enforce the use of app specific passwords. As my users are potentially lazy I am struggling to convince them towards the usage of these app passwords.

I am also pretty sure I have seen a config flag for that, but I am not able to find it now that I’d like to activate it. So any hint into a possible direction would be highly appreciated!
