What’s the authentication duration when checking “Keep me logged in”

If you click “Keep me logged in” (or “Remember me”) in Gandi's Log in page,
the session doesn’t have a maximum duration, and will remain active for the
whole browser’s session duration.

With the browser’s “Restore Previous Session”, “Continue where you left off”
“Reopen closed tab” or “Reopen all windows from last session” option,
you will remain authenticated until you explicitly log out.

If you don’t restore your tabs or session, you will have to log in
each time you close and re-open your browser.
