A method and a system allow accessing several of a user's controlled access accounts by presenting the credentials of only one of the accounts. The method may include (a) storing the credentials for each of the user's accounts; (b) receiving from the user credentials corresponding to any of the user's accounts; (c) presenting the received credentials to access the corresponding account; and (d) upon successful access of the corresponding account, using the stored credentials to access one or more of the user's accounts without requiring the user to present the corresponding credentials. For each of the user's accounts, the credentials are stored encrypted, using a randomly generated key, common to all the encrypted credentials. In addition, the randomly generated key is encrypted using the credentials of each of the accounts. In that manner, plain-text copies of neither the random key nor the credentials of the accounts need to be stored. |
