Change password on all switches

[Anonymous]

I'm looking to change all my switches' paswword to a new scheme for protection purpose. Does anyone knows how or what utility to use to mass change the password at once?

I would use an expect script that cycled through a list of switches, log on with the current password and then run passwd, enter current password again and then new password 2x. i use something like this when I install new switches.
