Employee turnover and Customer access information

beboelke

Many of us here work for firms which have numerous customers whom we must access in order to provide support/updates/etc. I was wondering what strategies some might use when an employee is terminated who previously had access to this information. Do you alert your customers to change passwords? Do you proactively change the passwords to your accounts on customer networks (this obviously can be very cumbersome for a firm with a large number of customers)? Is anyone familiar with any tools for managing this kind of information?
