01 // WHAT THE CHECK VERIFIES

What the check verifies

Analyses the cookies set on the first visit and the attributes of each one: Secure, HttpOnly and SameSite. Cookie values are never read or stored.

02 // WHY IT MATTERS

Why it matters

A session cookie without Secure can leak over HTTP, without HttpOnly it is exposed to scripts and without SameSite it is more exposed to CSRF.

03 // HOW TO READ THE RESULT

What each result means

OK
No cookie on the first visit, or all of them with the expected attributes.
WARNING
A cookie without Secure on an HTTPS site, a session cookie without HttpOnly or SameSite=None without Secure.

ERROR and TIMEOUT mean the query did not finish (the source was down or slow), not a problem with the domain: run the check again.

04 // HOW TO FIX

How to fix

Secure on every cookie of an HTTPS site and HttpOnly on session cookies. In PHP: session.cookie_secure = On, session.cookie_httponly = On and session.cookie_samesite = Lax in php.ini.

Set-Cookie: session=…; Path=/; Secure; HttpOnly; SameSite=Lax
