The Password SpecChar control defines the use of special characters in user passwords.
Teradata Database has a simplified set up for defining special character options, which uses a single character to represent each valid combination of the following four options:
- Special characters are allowed in a password.
- The username for the user is allowed in the password string.
- Alpha characters are allowed but not required.
- Mixed upper and lower case characters are allowed but not required.
The values are not case sensitive.
When you specify a single letter SPECCHAR setting, the system sets the status of each of the four options using the status indicators shown in the following table. Each status indicator defines how the system enforces a password parameter that has that status.
| Status Indicator | Description |
|---|---|
| Y | Allowed but not required |
| N | Not Allowed |
| R | Required |
