Login Security
Login security determines whether a user can log in to the application. This level of security is always active and requires that users specify a valid user ID and password combination before they can log in.
If, after three login attempts, the user has still not entered a valid user ID and password combination, the Logon screen closes. The user must relaunch the application and attempt to log in again.
For details about logging in to the system, refer to User Guide: QAD Customer Relationship Management.
