A computer system provides a unified password prompt for accepting a user power-on password or an administrator password. A password string entered by the system administrator at the unified password prompt is compared with a stored power-on password. If the user password string matches the stored power-on password, then access to system resources is granted. If the user password string does not match the stored power-on password, then the user password string is compared to a stored administrator password. If the user password string matches the stored administrative password, then access to system resources is granted. If the user password string does not match the stored administrative password, then the system administrator is given a predetermined number of times to enter a password string matching either the stored power-on password or the stored administrator password. If a password string matching either the stored power-on password or the stored administrator password is not provided in the predetermined number of times, access to system resources is denied. The unified password prompt does not require a system administrator to know a user's power-on password in order to access system resources. The unified password prompt also permits a system administrator to configure a plurality of computer systems by providing a single administrative password rather than a plurality of user power-on passwords.

One embodiment of the present invention provides a system that facilitates accessing to a plurality of applications that require passwords. When the system receives a request for a password from an application running on a remote computer system, the system first authenticates the request to ensure that it originated from a trusted source. Next, the system uses an identifier for the application to look up the password for the application in a password store, which contains passwords associated with the plurality of applications. If the password exists in the password store, the system sends the password or a function of the password to the application on the remote computer system. Hence, the system creates the illusion that there is a single sign on to a large number of applications, whereas in reality the system automatically provides different passwords to the applications as they are requested. In one embodiment of the present invention, the request for the password includes computer code that when run on the local computer system requests the password on behalf of the application on the remote computer system. In a variation on this embodiment, the computer code is in the form of a JAVA™ applet that runs on a JAVA™ virtual machine on the local computer system. In one embodiment of the present invention, the JAVA™ applet is a signed JAVA™ applet, and authenticating the request involves authenticating the JAVA™ applet's certificate chain.

A solution for computing password strength based upon layout positions of input mechanisms of an input device that entered a password. A password including an ordered sequence of at least two characters can be identified. A position of each of the characters of the sequence can be determined relative to a layout of an input device used for password entry. Each position can correspond to an input region (key) of the input device (keyboard). A proximity algorithm can generate a proximately score for the determined positions based upon a pattern produced by the positions given the layout of the input device. A password strength score can be computed based at least in part upon the proximity score.

A password evaluation system is provided for determining the password strength of a password. A password is provided for evaluation. The password is parsed and substrings are identified from the password. Each substring is associated with a pattern that can generate the substring. The substrings are scored to determine a substring strength measure for the substring. The substrings are combined to identify non-overlapping substring combinations, which together make up the password. The combinations are assigned a combination strength score based in part on the substring strength of the substrings contained in the substring combinations. The substring combination with the lowest combination strength measure is identified and the associated combination strength measure is used as the password strength measure for the password.

Password aging based on the strength of the password provides an incentive for users to generate and/or memorize more complex passwords. The strength of the password is computed from a formula that relates the length of the password and the types of characters contained in the password to a strength value, which can be performed using a lookup table having values for different characteristics of the password, determining partial strength values corresponding to the ranges in which the characteristics fall, and then adding the partial strength values. Alternatively, a separate password strength application may be used to provide the strength value, which is entered by the user or administrator generating a new password. Alternatively, the password may be generated based on a specified desired expiration period, with the strength computation performed to ensure that the strength is sufficient to merit the desired expiration period.

Methods and systems for accessing computer data and systems require different sequential and serial passwords to drive a user into a tiered set of sub-accounts of graduated access. At the same time, the tiered hierarchy of access acts as a honey pot system where remote intruders would statistically tend to break through the slightly less secure passwords first, triggering the notification system upon entry into the restricted or firewalled honey pot or virtual systems. With this system, the system administrator can manage multiple sessions for each user where the passwords are of a different level of security based on commercially available password strength tools. The system administrator creates the less secure passwords and lower access sub-accounts and optionally allows users to have such lower levels.
