A way to bypass a Chrome interstitial page is to type a secret keyword. Until today, this not-no-secret keyword was "badidea". And it just changed. So here it is, the new one is "thisisnotsafe".
Want to try it safely in Chrome Canary? Go to https://expired.badssl.com, type "thisisnotsafe" and enjoy.
Note that if you have no idea why you would want to bypass this kind of page, you may not want to use this trick ;)
