Is your feature request related to a problem? Please describe.
When using the new feature described in #31005, passwords sent via email should be one-time only. This behavior could truly implement a "secure view" of files and therefore prevent any opening from an unauthorized party (if sharing the password with someone for example)

Describe the solution you'd like
Once a requested password has been used, prevent the password to be used again

Describe alternatives you've considered
N/A

Research direction

Start by reading the implementation and discussion in issue #31005, which introduced temporary passwords sent by email. Trace the password validation and successful-use flow, then inspect any related tests. Done means a requested password is rejected after its first successful use while retaining the existing sharing behavior.
