The application is free for up to 15 passwords. If you want to add more than 15 passwords, you will need to purchase the PasswordsApp PRO upgrade within the same application. The purchase process is very simple and fully guided: when trying to add a new account when you already have 15, the system will suggest that you upgrade to PasswordsApp PRO via Apple's purchasing platform, a secure system with guarantees for the buyer

Make sure that you are signed in to all your devices with the same email. To do this, log out of each device on which you have the application installed (you can do this from the settings section, which has the following icon: ) and sign in to each one again.

Once in the store, press the button in the top right (Restore)

This is not possible. The master password cannot be recovered. In fact, when a user creates an account in PasswordsApp, they must activate a switch indicating that they have understood that the master password cannot be recovered
