The Facebook Connect button that appears on websites throughout the Internet may soon have company, as rival social network Google Plus Tuesday rolled out Google Plus Sign-In, which performs similar functions to Facebook Connect by allowing users of Google Plus, Gmail, YouTube, and other Google services to use their credentials to sign into applications.
Signing into websites with Google also allows users to install those sites’ mobile apps with one click, where applicable. And Google users can manage their setting by clicking on plus.google.com/apps.
Google Plus Director of Product Management Seth Sternberg wrote in a post on the social network’s developers blog:
Sometimes you want to share something with the world (like a high score), but other times you want to keep things to yourself (like fitness goals). With Google Plus Sign-In and Circles, you decide who to share with, if at all. In addition: Google Plus doesn’t let apps spray “frictionless” updates all over the stream, so app activity will only appear when it’s relevant (like when you’re actually looking for it).
Pictures and videos are great for viewing, but sometimes you actually want to do stuff online. That’s why, when you share from an app that uses Google Plus Sign-In, your friends will see a new kind of “interactive” post in their Google Plus stream. Clicking will take them inside the app, where they can buy, listen to, or review (for instance) exactly what you shared.
Sternberg also shared the following list of websites that have already added Google Plus Sign-In buttons:
Sternberg appeared to take a couple of potshots at Facebook Connect, both with his comment above, “Google Plus doesn’t let apps spray ‘frictionless’ updates all over the stream,” and with this other sentence in his blog post:
It’s simple, it’s secure, and it prohibits social spam.
Readers: Do you think the new Google Plus Sign-In button can make inroads against Facebook Connect?
