Facebook has been prompting some users registering for the first time to hand over the passwords to their email accounts, the Daily Beast reported on Tuesday—a practice that blares right past questionable and into “beyond sketchy” territory, security consultant Jake Williams told the Beast.
A Twitter account using the handle @originalesushi first posted an image of the screen several days ago, in which new users are told they can confirm their third-party email addresses “automatically” by giving Facebook their login credentials. The Beast wrote that the prompt appeared to trigger under circumstances where Facebook might think a sign-up attempt is “suspicious,” and confirmed it on their end by “using a disposable webmail address and connecting through a VPN in Romania.”
It is never, ever advisable for a user to give out their email password to anyone, except possibly to a 100 percent verified account administrator when no other option exists (which there should be). Email accounts tend to be primary gateways into the rest of the web, because a valid one is usually necessary to register accounts on everything from banks and financial institutions to social media accounts and porn sites. They obviously also contain copies of every un-deleted message ever sent to or from that address, as well as additional information like contact lists. It is for this reason that email password requests are one of the most obvious hallmarks of a phishing scam.
“That’s beyond sketchy,” Williams told the Beast. “They should not be taking your password or handling your password in the background. If that’s what’s required to sign up with Facebook, you’re better off not being on Facebook.”
“This is basically indistinguishable to a phishing attack,” Electronic Frontier Foundation security researcher Bennett Cyphers told Business Insider. “This is bad on so many levels. It’s an absurd overreach by Facebook and a sleazy attempt to trick people to upload data about their contacts to Facebook as the price of signing up… No company should ever be asking people for credentials like this, and you shouldn’t trust anyone that does.”
A Facebook spokesperson confirmed in a statement to Gizmodo that this screen appears for some users signing up for the first time, though the company wrote, “These passwords are not stored by Facebook.” It additionally characterized the number of users it asks for email passwords as “very small.” Those presented with the screen were signing up on desktop while using email addresses that did not support OAuth—an open standard for allowing third parties authenticated access to assets (such as for the purpose of verifying identities) without sharing login credentials. OAuth is typically a standard feature of major email providers.
Facebook noted in the statement that those users presented with this screen could opt out of sharing passwords and use another verification method such as email or phone. The company also said it would be ending the practice of asking for email passwords.
This beggars belief!
