There are many SSO (single sign-on) providers, with Facebook and Twitter on the market.
Since yesterday Google+ joined them, but with some extras. The new Google+ sign-in is targeted to developers and users, who will be able to sign-in simply and securely with a Google account, getting all the benefits of using their web and mobile apps. Users will be able to simply and securely experience the app’s social functionalities on desktops and mobile devices, without the spamming and spreads in social posts.
1. Simple and secure.
Well, all SSO providers are saying the same, so there are no surprises. And the security is as much as the security of the provider. For Google SSO this means also that you can use the 2 step verification which really brings the security on the next level. The steps to sign-on with Google+ are not so different from the other providers.
2. Desktop and mobile together
Here begin the differences. If your app has both web and mobile version now when the user signs in to a website with Google, (s)he can install its mobile app on her/his Android device with a single click.
3. Sharing not spamming
In difference to the “frictionless” sharing, the G+ SSO requests that the users select who would see their activities in the app. My favorite option is “Only you”. It is also a good reminder and reference what you did, if you want to get to it later.
4. The action pops out of the app
When you share from an app that uses Google+ Sign-In, your friends will see a new kind of “interactive” post in their Google+ stream. Clicking will take them inside the app, where they can buy, listen to, or review (for instance) exactly what you shared.
And of course there is an integration with Google Analytics, so the app owner would know very well where the app perform best.
What could this mean for us?
1. I expect that the SSO integration with G+ social network and the option to reach conversion in one step could be very lucrative for some of our customers, so we’ll have to learn a new SSO API very soon.
2. The new channel to push a mobile app and directly relate it with the web app would make the mobile apps much more desirable for the current and future web app/site owners, so we’ll have to strengthen our building skills for mobile apps (HTML5, Phonegap and/or native).
