Abstract: The system has a user terminal. A client provides access for the user terminal to data entries stored in a database. A database holds information consisting of one or more data entries and data identifications connected to the data entries. The client forms data identification for a certain data entry to be stored in the database from a unique user name and a master password. A pair of the data identification and the data entry is stored. Access for the user terminal is provided to a data entry stored in a database by using the master password, and the unique user name.
