Google Chrome 63, expected to be released sometime around December, will label resources delivered over the FTP protocol as “Not secure”, a member of the Chrome security team has shared.

This change is part of Google’s continuous effort to “accurately communicate the transport security status of a given page.”

“We didn’t include FTP in our original plan [which involved marking HTTP as non-secure], but unfortunately its security properties are actually marginally worse than HTTP (delivered in plaintext without the potential of an HSTS-like upgrade).”
