I was wondering if there would be a way to sign in to a third party website (like deezer) with a nextcloud account ? Of course the website would have to handle this feature. It would be like the google+ feature.
I am asking this question because I think a problem nowadays is the need to have an account for each website which leads to a spreading of personal information over the web and difficulties to control it.
A second one is the need to change my “preferred password” because one website only accepts numbers…
So what do you think ? Is it a good idea ? Is it possible ?
