Google Chrome 86 Security Update

Google is moving towards a more secure web.

As part of a long-term plan to mark all HTTP sites as non-secure this new Google Chrome release (Oct 06, 2020) will now label your site as Not Secure.

Beginning in M86, Chrome will warn users when they try to complete forms on secure (HTTPS) pages that are submitted insecurely. These “mixed forms” (forms on HTTPS sites that do not submit on HTTPS) are a risk to users’ security and privacy. Information submitted on these forms can be visible to eavesdroppers, allowing malicious parties to read or change sensitive form data.

Specifically, Chrome will be making the following changes to communicate the risks associated with mixed form submission:

  • Autofill will be disabled on mixed forms.
    Note: On mixed forms with login and password prompts, Chrome’s password manager will continue to work. Chrome’s password manager helps users input unique passwords, and it is safer to use unique passwords even on forms that are submitted insecurely than to reuse passwords.
  • When a user begins filling out a mixed form, they will see warning text alerting them that the form is not secure.Chrome OS
  • If a user tries to submit a mixed form, they will see a full-page warning alerting them of the potential risk and confirming if they’d like to submit anyway.Computer network security


Before M86, mixed forms were only marked by removing the lock icon from the address bar. We saw that users found this experience unclear and it did not effectively communicate the risks associated with submitting data in insecure forms.

We encourage developers to fully migrate forms on their site to HTTPS to protect their users. Developers with questions are welcome to email us at
