Change profil picture

Hello,
is it possible to change the profile picture of my users?
I have set up a Nextcloud instance for the family. Also have the passwords for the users. But is it generally possible to change centrally the profile pictures of my users?

If you have their passwords, you can login to their accounts and then change their profile pictures.

No. But you could try this app… Impersonate - Apps - App Store - Nextcloud
