Signed up for a warehouse stationery account the other day, and they emailed my user id and password in plain text after signup.
I emailed them and pointed out that they should encrypt their passwords properly.
Got a reply (which is really good) that they will stop emailing passwords and that their passwords are encrypted.
But, they should be using one way encryption.
It is interesting how big companies get this stuff wrong, considering you would think they have the most resources.
