Originally created by @bilogic on 9/29/2023

While trying to test out multi user behavior, I saved the various user passwords into my vault.

When loading /#/settings/security/change-password, the Chrome extension autofills the Current master password and Master password hint. The problem is, Master password hint is in plain text and it exposes the autofilled password.

Is there a way to break this behavior? Preferrably on just this page, perhaps by renaming the input tag's id that is masterPasswordHint to something else?
