Why is your Perl site asking me to log in with another site's credentials?
Yesterday I came across another Perl-related site, called PrePAN, that asks me to log in with some other site's login information. I've seen this before on MetaCPAN and Play Perl and it makes me very uncomfortable. It goes against the security advice that I've been given for decades.
IT professionals have been encouraging people to use different passwords for different sites for many years. Yet, here are three Perl sites asking users to share their login credentials for another site. (DANGER, WILL ROBINSON!) If MetaCPAN wasn't such a popular and well respected web site I would assume some malicious and nefarious purpose. Even with honest intentions, if my login information at the "other site" is compromised, what's to stop someone from then using those credentials to log into MetaCPAN, PrePAN, or PlayPerl and wreak havoc upon my accounts or impersonate me?
I'm surprised that no one else has voiced concern about this. What's going on with these sites? If you've logged in to these sites, what made you decide to throw caution to the wind and do so?
