Password Protect/Lock Filters

[rthaut]

Implement functionality to lock filter management (at least filter removal, maybe also filter creation) behind a "password."

Basic requirements:

• [ ] User must somehow "opt in" to locking filter management behind a password
• [ ] User must create a password only after "opting in," and only if no current password is set
  • User must be automatically "opted out" upon failure to provide/save initial password
• [ ] User can change or remove password altogether, but only after providing current password

Additional considerations:

• Is a recovery mechanism needed? Or should the user be required to uninstall & reinstall?
• Where/how should the password be stored (local vs. sync storage, encrypted vs. hashed)?
  • This will probable be partially driven by the decision regarding recovery
• Should filters be displayed (read-only) and/or exportable without entering the password?
  • Maybe this should be part of the "opt-in" process, allowing the user to choose
• Should the user be allowed to create new filters without entering the password?
  • Again maybe this should be left to the user to decide during "opt-in"

Why is this feature still not implemented?
