PassGenR is a simple, easy-to-use utility that allows the generation of secure random passwords. Intended for Network and System Administrators who routinely need to create user accounts, PassGenR incorporates several options to facilitate the creation of truly random passwords.

Password length and types of characters (upper and lower case, numerics, punctuation) are selected through an intuitive interface, and settings are of course remembered from use to use.
