url != clickable object


No problem with URLs in email.

No problem with clickable objects that are unrelated to security.

Minor problem with URLs that lead to changing passwords but can be
mitigated by making the URL very plain and easy to read, even by a
non-techie. They'll at least have to see the thing, even if the mail
client automagically makes it clickable.

Big problem with clickable objects which lead to PII (personally
identifiable information) or passwords. That's how phishing works -- a
disguised url that you either see at all or whose incorrect nature
slips right past your brain. The only known working solution is to
train folks to *never* click security-related URLs in email. Copy and
paste only, and only if they're readable and read right.
