Since January this year Google Chrome started adding warning labels for any websites asking for passwords and/or credit card information which haven’t yet added SSL protection.
In case you’re not familiar with SSL, it’s a type of encryption which prevents any communications between the visitor and the site from being read or forged by a 3rd party.
So, in other words, visitors on SSL secured sites are protected from hackers trying to steal passwords or credit card data.
This is why you MUST add SSL certificates to any of your websites not currently secured with them.
Ignore this warning at your peril, because visitors arriving at non-secured sites via the Chrome browser will begin seeing ‘Not Secure’ in their browser!
