A Chrome extension, from Google, designed to try and help warn you about phishing attacks.
I have, at one point, fallen for a phishing attack against one of my old Google accounts; it was at the end of a long, shitty day, and I should’ve known better but, just that one time, I didn’t.
One minute of brain-dead typing. Weeks and weeks of work afterwards trying to re-secure my accounts. Bleurgh.
