Not a bad question at all, no worries.<p>When you save your password on your PC, the password is saved into an encrypted store that is physically on that PC, and to get it to your phone you need to have the application (be it web or native android) open and your vault unlocked so that the two can synchronize.<p>What I do is to prepare the phone vault by unlocking it and synchronizing right away as I make changes if something is critical.<p>That is the trade-off when it comes to convenience as compared to something like BitWarden, for example. There the credentials are stored in a centralized database that your PC or phone can reach independently of each other.<p>EDIT: More details here: <a href="https://www.cryptex-vault.com/docs/synchronization" rel="nofollow">https://www.cryptex-vault.com/docs/synchronization</a>
