answer:I avoid that convenience. Imagine a hacker happens to crack a site you routinely visit or capture your login credentials to a site as you’re visiting it. That one site is compromised. Could be a pretty big problem if it’s your bank or a credit card account, but it’s just one site to deal with. Now imagine how much worse it is when a hacker finding one vulnerability on your system or any site you visit suddenly has the master key to open everything you do! Thanks for the convenience Google, but no thanks. Managing separate user names and passwords ain’t that hard to do.
