Hi,
Today, I received an email from fas@fedoraproject.org with the subject line "Fedora Account System: please verify your Bugzilla email address". This email has a unique link to accounts.fedoraproject.org.
Based on the context, it seems legitimate. However, I noticed that clicking the link will take you to a sign-in page asking for credentials to your account. That seems strange to me, because it already has a unique link that's associated with the verification of a specific email in a specific FAS account, so asking for credentials should be completely unnecessary here. Asking for credentials makes this appear to be a phishing attempt, because that's how a phishing email would behave (appearance of legitimacy, requesting credentials when not needed).
I think the FAS developers should remove the requirement to sign-in for these verification emails, to reduce the appearance/behavior of phishing. The email itself says these emails are "To improve security". If that is a goal, then Fedora systems should avoid training users to supply credentials when not needed.
Thanks, Christopher
