How does browser know HTTPS?
4 Answers. Your browser remembers the port and protocol from previous interaction with the site. Paypal uses HTTP Strict Transport Security. This means that the server had sent (perhaps via port 80) a response header including Strict-Transport-Security:max-age=63072000 before you even started looking.
How does a Web browser detect if a website is secure?

What happens when a web page is not secured with https?

Authentication: Unlike HTTP, HTTPS includes robust authentication via the SSL/TLS protocol.
