Enforce password policy for shared links

[BornToBeRoot]

The password policy under Administration/Security is not applied on shared links in talk.

Since it is a general security setting (and not only for sharing files), it should apply to every shared link including talk rooms.

Describe the solution you'd like

1. The password field in talk should respect the settings in Administration/Security/Password policy
   

2. There should be an option (like in Administration/Sharing) to enforce password protection for talk conversations. This would prevent users from creating rooms without a password.
   

3. People invited by mail should get a second e-mail with a custom password for this talk conversation (like sharing via mail).

Has this really been fully implemented?

I cannot find an option to enforce all link shares to be password protected.
