Master Password is available for: iPhone, iPad and Mac users; for Windows desktop users, for Android and as a web app (still in beta). Master Password is said to be based on an ingenious password generation algorithm that guarantees your passwords can never be lost. This new service doesn’t save your passwords in an encrypted vault or in the cloud, being generated on-demand from your name, the site and your master password. Thus, there’s allegedly no risk on your passwords being intercepted or divulged to others. Being based on a ‘stateless algorithm,’ the software comes with a variety of built-in password types, ranging from basic to more advanced levels of security. Master Password also offers a hybrid solution which allows users to save custom passwords in the app which are AES encrypted using a large key derived from the master password. Follow this guide to see how you can start using the service and read their extensive explanation with regards to the security measures employed. Indeed, there seems to be a lot of work behind the curtains involved in the making of this service, so go ahead and give it a try if you are looking for such a service.
