Pseudorandom Password Generator

Pseudorandom passwords are generated by selecting a password length and a range of characters. Click a particular character to include or exclude it. These selections are encoded in the alphanumeric string at the bottom. This string can be used to specify a password scheme for a group of users by mailing that string or sharing a version of this Demonstration which quotes that range specification in its popup menu.

Use the automatic randomization mode or customize the random seed by six movements of the 2D slider.
