Worth knowing you can actually do this with simplelogin as they are owned by proton.

However support using webfinger authed Oauth2 ( RFC 7033) is not currently implemented and so you cannot use it for stuff like tailscale:

This could also be good for marketing on proton's end. People singing in will see "Sign In With Proton", and then might search google, to find out what proton is.

It would be so cool if I could use this internally on my own local sites with OIDC.

That way, one would actually only require one password / passkey to log into all their services, password manager, cloud and email.

it would be lovely if implemented like the apple one: https://support.apple.com/en-us/102379

to have disposable account without data related without having to use pass

Wanted to create similar idea, that is AWESOME I'm not the only one who understands NECESSITY for this

For example- signing in the X [Twitter]

Something like login with apple, login with facebook and login with google. Same thing but login with Proton Mail!!!!!

I love that idea. But then, developers need to implement it, right? I'm not sure companies are ready to pay for this since Proton is still a niche compare to Google.

Allow user access managment with Proton/SimpleLogin and use SimpleLogin as oauth provider / SSO for other platforms like Sign in With Google or 365. This will make Proton more central in organisations and can greatly benefit small enterprises who do not have this yet and even families.

Yep, just now i was looking into this, was going to use protonmail api's. Does not seem that ill have much luck with this

I'm switching back to Google because of this. The ease of OAuth is amazing. Plus, as a developer, I would like to offer the option.
Furthermore, it's publicity for your service.

First thing I went looking for when I signed up for protonmail.

Awesome Idea, I hope they do this.

SSO is now a standard in the industry. In order to use ProtonMail as a Central Identity Service this is a must have

Yes please. I would give this option to users of all my web services for sure.

Vote proton

Find another web application that is interested in offering it as option. Make the deal ;)

Great idea 😄 maybe with email adress protection like apple oauth.

I understand what you say, however if you want to access to other website in this world you need to create other log in credentials, therefore I prefer to rely on protonmail and know what is going to happen with my data rather than any other provider.
In order to resolve your concern, protonmail could simply create an avatar with the info you like that a user can use for these types of login.

If protonmail provide an authentication process for any new platform, start up or website and the process is managed and designed by protonmail, I believe the respect of privacy would be more likely.

If you wish to make this world better you need to provide better alternative to users. If you do not, I can`t blame users that rely on other service providers that steal their data.

Most of the current Oauth providers are all social media sites. Would be great to have this feature for SSO from a company I trust.

It could also help promote ProtonMail by getting more people aware of the alternatives.
