An urgent request, that phrase has always sounded funny to me. The 1st question I would ask with any new management; "Why are we doing this?" Disabling syncing the passwords with an online account I totally understand. But disabling cashing passwords locally is a different story. Depending on how well SSO is setup in your environment it may cause more problems than good. Edge syncs passwords between devices with Azure by default, I would find out if that is enabled in your Windows environment (this also effects edge on macOS with a network account signed in).
For Safari I believe this is done with a restrictions configuration payload. Disable the password stuff under functionality.
For Chrome you would disable the password manager.
Firefoxes documentation is not quite as good, but they provide you the json. I would assume this is in firefoxes password manager also.
Documentation for Edge. Microsoft provides a custom schema you upload in to JAMF and just select the correct drop down.
Thanks for the details input
I could block PasswordManger for chrome using jamf config profile.
The config profile couldn't be applied on firefox.
Compatibility: Firefox 60, Firefox ESR 60 (current version 102.0)
