You can now include discord, github, gitlab, and twitter in your authorization requests and Hellō will ask the user to link and select the requested provider(s) to provide you with a verified claim of their identifiers on those services.

As usernames can be changed, we provide both the username, and the permanent id from the provider:

{ // ID Token payload
    ...
    "discord":{
        "username":"dickhardt",
        "id":"932454643529834567"
    },
    ...
}

Try it out for yourself in the Hellō Playground!
