As well as exposing users to potential security breaches, those who provided passwords found that, immediately after their email was verified, the site began \u201cimporting\u201d contacts without asking for permission.<\/p>\n<p>Facebook has now admitted it was wrong to do so, and said the upload was inadvertent. \u201cLast month we stopped offering email password verification as an option for people verifying their account when signing up for Facebook for the first time,\u201d the company said.<\/p>\n<p>\u201cWhen we looked into the steps people were going through to verify their accounts we found that in some cases people\u2019s email contacts were also unintentionally uploaded to Facebook when they created their account,\u201d a spokesperson said. \u201cWe estimate that up to 1.5 million people\u2019s email contacts may have been uploaded. These contacts were not shared with anyone and we\u2019re deleting them. We\u2019ve fixed the underlying issue and are notifying people whose contacts were imported. People can also review and manage the contacts they share with Facebook in their settings.\u201d<\/p>\n<p>The issue was first noticed in early April, when <a href=\"https:\/\/www.thedailybeast.com\/beyond-sketchy-facebook-demanding-some-new-users-email-passwords\" data-link-name=\"in body link\" class=\"u-underline\">the Daily Beast reported<\/a> on Facebook\u2019s practice of asking for email passwords to verify new users. The feature, which allows Facebook to automatically log in to a webmail account to effectively click the link on an email verification itself, was apparently intended to smooth the workflow for signing up for a new account.<\/p>\n<p>But security experts said the practice was \u201cbeyond sketchy\u201d, noting that it gave Facebook access to a large amount of personal data and may have led to users adopting unsafe practices around password confidentiality. The company was \u201cpractically fishing for passwords you are not supposed to know\u201d, according to <a href=\"https:\/\/twitter.com\/originalesushi?lang=en\" data-link-name=\"in body link\" class=\"u-underline\">cybersecurity tweeter e-sushi<\/a>, who first raised concern about the feature, which Facebook says has existed since 2016.<\/p>\n<p>At the time, Facebook insisted it did not store email passwords but said nothing about other information gathered in the process. Shortly after, <a href=\"https:\/\/www.businessinsider.com\/facebook-asks-new-users-email-passwords-2019-4?r=US&amp;IR=T\" data-link-name=\"in body link\" class=\"u-underline\">Business Insider reported<\/a> that, for users who entered their passwords, Facebook was also harvesting contact details \u2013 apparently a hangover from an earlier feature that Facebook had built expressly to take contacts with permission \u2013 except in this new implementation, users had not given consent.<\/p>\n<p>The company said those contacts were used as part of its People You May Know feature, as well as to improve ad targeting systems. While it has committed to deleting the uploaded contacts, it is not immediately clear whether it will delete the information it inferred from those uploaded contacts \u2013 or even whether it is able to do so. Facebook did not immediately reply to a query from the Guardian.<\/p>\n<p> READ MORE <a
