Hi Thom, and welcome!
The short answer to your question is: Spectre is the latest version of what was formerly named Master Password.
Master Password is a project I started in 2011. In 2018 I began work on rewriting and rebranding the application, algorithm and project. The aim is to create a platform that will expand beyond just passwords, extending the benefits out to other areas.
Master Password has been renamed and is now re-launching as Spectre, first on iPhone, coming later to the other platforms. Spectre will replace Master Password and development on Master Password will wind down. You can still keep the Master Password app around with your user in it until you are comfortable with Spectre and ready to fully switch. The process of migration has been made as easy as possible for you.
Spectre comes with more modern platform support, rewritten in a modern new development language for improved security and reliability, and integrates much more tightly with the operating system (such as by offering password AutoFill).
Spectre, like Master Password, is open-source, authored entirely by myself, available for free, forever. It will also be financially supported by a new model for those who are interested in the improved systems integration and convenience features, which will allow me to focus my efforts into keeping this project alive and growing.
Let me know if you have any further questions!
A quick list of additional capabilities in Spectre:
- Redesigned modern interface
- Personalizable user interface
- Incognito users
- Privacy improvements such as enhanced identifier decoupling and "Offline Mode"
- Login identicon for typo detection
- Explicit Universal Clipboard & Handoff support
- Explicit support for FaceID
- Password Auto-Fill from other applications and browsers
- Third-party application storage & file sharing
- Opening sites from within the app
With more to come!
