According to Excalibur “instead of using a master password we use your phone, the most personal device that you always carry with you, the phone will ask your for you specific acknowledgment for every action that might require your attention. Phone application is protected by a pin code or a password. Instead of synching your data across computers, Excalibur is cloud based by design, there is no synching required. And also instead of storing your sensitive data in one place as everybody else does- we stores them decentralized, one cryptographic part on your phone and one in our cloud. The only place where the data is reconstructed is in your computer Ram for the shortest possible duration necessary. If your phone gets stolen- nothing can be extracted from it, if Excalibur cloud gets hacked nothing can ever leak”
