Sign in to a third party website with nextcloud account

🍱 Features & apps App ideas

Hi everybody,

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 ?

This reminds me of https://blog.codinghorror.com/your-internet-drivers-license/
Check out http://openid.net/ and http://wiki.oauth.net/w/page/25236487/OAuth-2
I don’t think Nextcloud should be used to solve this problem.

Can I get a third-party help for customization of https://epsonsupports.net/blog/fix-error-code-0x803c010b/ and I also want to make some changes in it. I want to make an account in nextcloud but facing some temporary issues.
