Cookie not set with SameSite attribute

As noted on solid-auth-client https://github.com/solid/solid-auth-client/issues/151, Chrome is requiring third party cookies to be set with SameSite=None and Secure. While this setting is not yet active on desktop, it is active on Android and therefore breaks all Solid apps using the nssidp.sid cookie from .solid.community.
This can still be bypassed by disabling chrome://flags/#same-site-by-default-cookies.
Presumably non-cookie based authentication doesn't have this issue but I'm not sure it's possible to turn off cookie-based authentication at the moment (https://github.com/solid/node-solid-server/issues/672)

I'm not an expert, but it appears the change required is in the definition of the express-session settings
https://github.com/solid/node-solid-server/blob/master/lib/create-app.js#L305
https://www.npmjs.com/package/express-session#cookiesamesite

It may be sufficient to simply use:

    cookie: {
      maxAge: 24 * 60 * 60 * 1000,
      sameSite:'None'
    }

It seems that http connections should also be completely dropped for authenticated sessions because the third party cookie won't be sent without cookie.secure=true anyway.

Comece em lib/create-app.js por volta da linha 305 e revise as configurações de cookies do express-session junto com a documentação do express-session. Reproduza o comportamento de nssidp.sid no Android Chrome com a aplicação de cookies SameSite e, em seguida, verifique se os aplicativos Solid autenticados conseguem estabelecer e usar a sessão sem interromper os modos de conexão compatíveis.
