We want to send a regular "letter" in the regular old postal carrier type of mail delivery method - to a bunch of users who we want to allow access to a secure web page.
They will login with the email address they have given to us - which we have marked in a CONTACT table for these individuals.
With that said - the letter does not need to include the EMAIL address - we can simply tell them to use the email they gave us.
The question becomes what do I tell them to use as a password? How bad of an idea is it to put a PASSWORD in this letter - and make it be the same INITIAL password for all these contacts that are going to be connecting??
Obviously I would "pre-expire" this initial password for each user - so they have to select a new one upon the initial login.
