• The new Python extension is now available. It allows customers to deploy and manage WSGI-based Python applications on their websites directly from Plesk.
  • The Plesk Mobile apps for iOS and Android and the Plesk Mobile Center extension have been deprecated, and are no longer available for new installations. In Plesk Obsidian 18.0.84, the Plesk Mobile Center extension will be removed from servers during the upgrade, and the Plesk Mobile apps will lose their server management features.
  • The Social Login extension has been deprecated and will be removed in Plesk Obsidian 18.0.84. After that, it will no longer be possible to log in to Plesk with a Google, Facebook, GitHub account, or with a passkey. Plesk usernames and passwords, as well as logging in with a WebPros Account, are not affected.

Are all of these above users normal and expected as users for the PLesk Obsidian emailer and web server?

If any are unexpected, which ones? Why?
 
Hi, @MHC_1 . The users look pretty standard to me. Here's a comparison with a default freshly set Plesk server on AlmaLinux 9.7:

From what I can see the only users missing on my end are:


Code:
rpc
setroubleshoot
cockpit
rpcuser
tcpdump

However, these look like legitime system users that are missing on my end only due to difference in the installed packages and components.
