The present invention concerns a computer-implemented method for securely storing credentials for offline use and copy-protected vault content, using a server and an application on a device of a user, comprising the steps of: a) said server storing said credentials, unable to decrypt said credentials by itself; b) said application storing encrypted credentials on said device, unable to decrypt said credentials without assistance of a relying third-party application and/or said user; c) being able to distribute said credentials across different devices of said same user, using both said server and interaction of said user;d) said user providing backup data without credentials to said server, in order to restore said credentials in case of loss of said device;whereby the method does not require a Secure Element but is secured using cryptographic keys and encrypted storage. In a second aspect, the present invention provides a system suitable for said computer- implemented method. In a third aspect, the present invention provides an application product suitable for said computer-implemented method.
