This may sound like a stupid question but our client would like to see all the passwords of all the users. Is there a way for the passwords to be shown in the backend when one is logged in as an administrator?

Thanks

No. Passwords are stored using a one-way hash, so not only is this a really bad idea from a security standpoint but it is also impossible.

Thank you, that is what I expected and after looking up "one-way hash" I found a great article opening it up further.
