Google has a password manager that syncs across Chrome and Android, and now the company is adding a “password checkup” feature that will analyze your logins to ensure they haven’t been part of a massive security breach — and there have been oh so many of those. Password checkup was already available as an extension, but now Google is building it right into Google account controls. And it’ll be prominently featured at passwords.google.com, which is the URL shortcut to Google’s password manager.
Your login credentials are compared against the millions upon millions of known compromised accounts that’ve been part of major breaches. Google says that it also monitors the dark web to some extent for collections of passwords — but most of the database that password checkup compares against comes from crawling the open web.
