nonsecure collection of passwords will trigger warnings in chrome 56

I got an email telling me that a link to a photo in a password protected gallery will trigger this warning.

As near as I can tell, this is occurring when I navigate to a public gallery in Chrome that has a photo on it that was collected from the password protected gallery. I have not given this link to anyone and if you try to go directly to it, you will see the unlock gallery message. But it shows up fine in the public gallery I collected it into.

I noticed also that if I click on the buy link after going to the public gallery as a visitor, not logged in, the link does not have https.

Is this going to be an issue?

Nonsecure Collection of Passwords will trigger warnings in Chrome 56 for http://redwoodtwig.com/

To: owner of http://redwoodtwig.com/

Beginning in January 2017, Chrome (version 56 and later) will mark pages that collect passwords or credit card details as “Not Secure” unless the pages are served over HTTPS.

The following URLs include input fields for passwords or credit card details that will trigger the new Chrome warning. Review these examples to see where these warnings will appear, and so you can take action to help protect users’ data. The list is not exhaustive.

The new warning is the first stage of a long-term plan to mark all pages served over the non-encrypted HTTP protocol as “Not Secure”.

Here’s how to fix this problem:

Use HTTPS pages to collect sensitive information
To prevent the “Not Secure” notification from appearing when Chrome users visit your site, move collection of password and credit card input fields to pages served using the HTTPS protocol.
