I'm vaguely aware of what single sign on is. Though I don't use it, it seemed non-intrusive. The most you would see buttons to login through Google, Facebook etc.
Now some sites have an entire banner pestering you to sign in through your Google account. It has a big continue button that takes you to Google and the button to close is a small x in the corner. On mobile this banner takes up a third of the screen.
Why do this?
No, they don't get paid. Its just an easy way to integrate your app with some sort of login/authentication floe, rather than building your own.
There are SSO solutions besides google. For example, Keycloak is open source but it is a PAIN IN THE ASS to manage it and set it up properly. Most people take the easy route and I don't blame them.
What I don't get why have this weird ugly banner for advertising Google's SSO. I often see it on Reddit's new interface for example.
I only use Google anything when I have no other option. I don’t know what kind of arrangement companies have with Google, but running an SSO service costs money, so companies that don’t roll their own normally pay Okta or some other such provider.
Okta runs an annual “Oktane” user conference, which in 2018 featured former US President Barack Obama as a keynote speaker.
Finally, a resident expert in single sign on.
Oh snap!
It's the loathsome dong-eater from that game I'm playing!
AAAAAAAAAAAAAAAAAAAAAAAAAAAAA
Because it expands google's monopoly and mass surveillance network.
