In any of these cases, you may see a “Not Secure” or “Website Not Secure” message in Safari:
- The website is encrypted, but its certificate is expired or illegitimate.
- The website's certificate is valid but the version of TLS is not secure (TLS version 1.1 or earlier).
- The website is unencrypted and asking you to enter password or credit card information.
Never enter your password or credit card number on sites with this warning. If you need to use the site, contact its owner or administrator and let them know that their site isn't secure.
If an unencrypted website has requested your password or credit card information, Safari warns you that the page you are on isn't secure.
If you tap or click into the form to sign in or enter information, you'll see a more prominent warning in the Smart Search field.
