Authentication with third party website

I’m building an app that provides a board view which requires authentication with a third party website. The third party website uses Google to authenticate users, by providing a “Sign in with Google” button that launches a dialog allowing the user to sign in with their Google credentials. Will this solution be reliable when used within a board view iframe or will some browsers block session cookies in the iframe? Any suggestions on the best approach?


From my experience, your best option is to open the authorisation process in a new window as some requests will be blocked by CORS as your view runs in an iframe.

const myWindow ='/authorisation', "_blank", "toolbar=yes,scrollbars=yes,resizable=yes,top=500,left=500,width=800,height=800");
    var self = this;
    var timer = setInterval(function() { 
      if(myWindow.closed) {
    }, 500);

Something like this has worked for me


Hey @Roobrick,

I think @mitchell.hudson suggestion might be best here (as usual, he is awesome) - my suspicion requests will be blocked by CORS as he mentioned. Could you try the solution he posted above?

Google also provides some information on adding Google sign-in to your webapp here.

Let me know if we can help with anything else!

Thanks @mitchell.hudson and @dsilva. I’m using a Google API at the moment to launch a popup window and it is working, although I don’t think it will work in an iOS webview should that be supported in the future.
