Abstract
A method and system for password validation. A user identifier (ID) and a user keying password are received from a user in conjunction with reception of a request from the user to obtain access to an application. The user keying password is a sequence of characters including at least one character from a first set of characters and at least one character from a second set of characters. The first set of characters are text characters allowed for defining a user password. The second set of characters are keying characters not allowed for defining a user password. It is determined whether the received user keying password matches a keying password reference. The keying password reference is based on a password definition rule.

A computer implemented method for password validation, said method comprising:
- receiving a user identifier (ID) and a user keying password from a user in conjunction with reception of a request from the user to obtain access to an application, the user keying password being a sequence of characters comprising at least one character from a first set of characters and at least one character from a second set of characters, the first set of characters being text characters allowed for defining a user password, the second set of characters being keying characters not allowed for defining a user password;
- and
- determining whether the received user keying password matches a keying password reference, the keying password reference being based on a password definition rule.
A computer-implemented system for password validation, said computer system comprising:
- means for receiving a user identifier (ID) and a user keying password from a user in conjunction with reception of a request from the user to obtain access to an application, the user keying password being a sequence of characters comprising at least one character from a first set of characters and at least one character from a second set of characters, the first set of characters being text characters allowed for defining a user password, the second set of characters being keying characters not allowed for defining a user password;
- and
- means for determining whether the received user keying password matches a keying password reference, the keying password reference being based on a password definition rule.
A computer program product, comprising a computer usable medium having a computer readable program that when executed on a computer causes the computer to perform a method for password validation, said method comprising:
- receiving a user identifier (ID) and a user keying password from a user in conjunction with reception of a request from the user to obtain access to an application, the user keying password being a sequence of characters comprising at least one character from a first set of characters and at least one character from a second set of characters, the first set of characters being text characters allowed for defining a user password, the second set of characters being keying characters not allowed for defining a user password;
- and
- determining whether the received user keying password matches a keying password reference, the keying password reference being based on a password definition rule.
