@richwang @vinismarques Welcome to the forum!
There are two older feature request topics relevant to your proposal, which have gained more traction. Please let me know if you wish for your feature request (and its votes) to be merged into one of the following:
For the second one of these, please note that the current master password reprompt function applies to “hidden” items (passwords, custom fields of the “hidden” type, etc.), so if the password history is made “hidden” (as requested in that thread), then the master password reprompt would also be expected to be enforced for viewing the password history (as you’re proposing here). If it would help, I could revise the thread title of that second feature request after merging your post.
