Same-site flags were removed in Chromium 91 - How can I disable them for local development?

Question

Previously I could disable the verification of same-site cookie in the chrome://flags using the following flags (pic 1) but it seems that in Chromium 91 they were removed (pic 2).

What can I do to disable this verification?

Answer 1

For the local development in chrome 91, we need to edit the cookie SameSite attribute and set it as None.

Answer 2

there is an temporary solution for this problem set an commond line in chrome/edge (v91) launch cofing like this:

Windows：open Chrome/edge shortcut's property，add: "--disable-features=SameSiteByDefaultCookies" after Target property

in my pc,it like ** "C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe" --disable-features=SameSiteByDefaultCookies ** finally

then restart your chrome/edge,try again

Answer 3

Starting from Chrome 91 these flags are not needed since it is now a default behavior. It means either this feature(s) must be configurable in settings or non-configurable at all (and this is our case!).

However, there are still similar launch feature flags available up until Chrome 94:

• SameSiteByDefaultCookies
• CookiesWithoutSameSiteMustBeSecure

For example, launch command in Linux then would be

google-chrome --disable-features=SameSiteByDefaultCookies,CookiesWithoutSameSiteMustBeSecure

I guess after Chrome 94 one has to just deal with it
