Teradata Wallet storage is especially beneficial for easy retrieval of passwords on application servers or other shared computers that host multiple users and connect to multiple databases. Users wanting to use retrieved data in logon strings must have a personal Teradata Wallet instance on each computer through which they access Teradata Database.
Passwords and other data are securely stored in protected form. See Encryption.
Each user can store data only in their own wallet, which is not accessible by other users. The system retrieves data only from the wallet belonging to the logged on user.
Teradata Wallet substitution strings are accepted by both the .logon and .logdata statements in the logon string, and by the corresponding logon functions in ODBC (14.10 and up only) and CLI applications and scripts.
