Re: Password Expatriation notification

Wouldn't it be easier to just require 15 or 20 character passphrases and never have them expire? (Two factor would be nice but not financially sound for the whole campus right now.) It would seem that it might not be too hard of a sell with the -- Never have to change it again.. angle. And passphrases are easier to type than the random crazy passwords..

I would whole-heartedly agree to your statement about providing emails from
IT WITHOUT links, but rather reference a known web site by name.  I think it
makes education and reinforcement of not clicking on links much easier when
IT never sends out links either.  :-)

I expressed this sentiment just before a recent round of emails were sent
regarding password changes only to be informed that it would be "too
difficult" for the users to do and thus they wouldn't bother to change their
passwords.  While I understand that the password change is critical, I think
sending links is today a greater risk because it encourages bad behavior on
the part of the user.

I will be interested to see what others out there have to say.

Best,
Cathy

We also send our users messages like this. However I'm concerned that it
would take very little effort to copy the content, spoof the from address
and href the links so they look genuine but take them to a random web server
which is setup with a copy of our real password management system.

For this reason I think we shouldn't provide links in emails that ask a user
to login to anything, but should advise they visit our main web page (i.e.
type it in themselves) and we give them a link off that. We can then also
tag on to "we never ask for your password" that "we never link to pages that
ask for your password".

Has anyone else tackled this particularly?

Cheers
James

And we also send out an email notice 14 days before expiration, and
again more frequently as the expiration approaches.  We have a single
enterprise credential for authentication to many systems, including
email.    We try to make our notification not-phish-like but still get a
few inquiries as to the validity of the message.  I usually
congratulate those paranoid souls.  At least it's better than believing
everything.
