If your Integration Server is configured to encrypt outbound passwords using Password-Based Encryption (PBE), your Integration Server will have a master password, which is the key used to encrypt outbound passwords. You need to enter the master password whenever you want to change to a new encryption key. In addition, some installations are configured so that Integration Server prompts for the master password when Integration Server initializes; without the password, Integration Server will start up in safe mode, which is described below.

Therefore, if you lose or forget your master password, you will need to restore it or reset it, depending on the circumstances. For more information, see Determining Whether You Can Restore the Passwords.
