Per https://developers.google.com/identity/sign-in/web/server-side-flow in order to get a refresh token, the client must grant offline access. However, I see no way to do that using the new API. What's the proper way to get a refreshed token using the Google button, so the user doesn't need to re-login every hour?
Authentication for sign-in has been separated from authorization for data access in he new API.
In the new API authentication does not require or use access or refresh tokens, instead a signed JWT ID token credential containing the user profile is shared after user consent. This greatly simplifies the level of effort and need to manage tokens during app sign-up or sign-in.
If you're performing authorization to access Google APIs and storing refresh tokens on your backend, then a server-to-server OAuth flow is appropriate.
Another clarification, user sign-in to your app and maintaining session state are separate concepts and should be handled separate from backend processes which may use an offline refresh token to perform actions through a Google API on behalf of the user while they are not logged in.

I'm new to react but i have previously worked on server side rendering websites
My objective is to make a website where at first only a sign-up, login page is shown and if the login was successful the user would be able to access other pages
I'm using and api which provide jwt tokens and jwt refresh tokens for authentication, the main token expires in 1hr and i need to auto generate new token by then in the background without the user knowing
So how should i go about implementing this any example code would be helpful
This site is about helping to solve specific programming issues, noone will write your app for you. The idea is to acquire the token via authentication, persist it in browser (local/session storage), then attach it as auth header to every api request. For refreshing the token implement some setInterval.
Context:
I am currently working on an embeddable widget, something akin to Intercom or
Hotjar, and have the need to authenticate users. Thus far, I got away with
using Passwordless authentication using Firebase auth but users complain that
it's a high friction process, and they'd rather not do it at all. The ideal
authentication solution would be to let users use their Google or Facebook
account and authenticate via OAuth2.
Problem:
Firebase Auth restricts authenticating via 3rd party auth providers if the
domain the user authenticates via is not whitelisted in the authorized domains
list. So if the user puts the code in abc.com, and tries to auth via Google
firebase rejects it because abc.com is not in the whitelist. Whitelisting the
domain of every client is unorthodox. I feel like the way I'm approaching it
is wrong because I can't correctly build up a mental model of how this would
work out. Technically cookies, sessions, etc. are pointless.
Question:
How would I go about providing the ability to let users authenticate via 3rd
party auth providers? Is this even technically possible?
Potential Solutions:
Host the widget at the main app in a dynamic route (the website where the user
would get the widget's code) and render this route as an iframe in the
client's website. (ex: /widgets/{widgetID} would have the widget). I don't
want to do this really because iframes are a serious pain but this sounds like
the most feasible.
I'd like to know more/better solutions to address this particular situation.
It doesn't matter even if it's from a different cloud provider or a different
authentication service. The goal is to authenticate the user from the widget
ideally via a 3rd party auth provider like Google.
EDIT: This is the error that I currently receive:
widget.js:2 auth/unauthorized-domain This domain (xyz.com) is not authorized to run this operation. Add it to the OAuth redirect domains list in the Firebase console -> Auth section -> Sign in method tab.
Based on your use case, you need to verify the domain ownership xyz.com by following this guide
After that you need to add xyz.comto Authorized domains your, as the error message mentioned.
Add it to the OAuth redirect domains list in the Firebase console -> Auth section -> Sign in method tab.
For more information please check this guide
Is not possible enable Google Sign In by using a domain unverified or unauthorized, this is to protect the access to your sites/projects by restricting the usage of the Firebase/Google credentials only for configured domains.
There is no way to disable this setting, Google sign in uses Oauth2 as authentication framework
I would like to build a small js library that can read a specific album from my account and display the photos within as a slideshow.
In this guide (https://developers.google.com/photos/library/guides/get-started), to access the API we need both ClientID and Secret. Is there any way to access the API using some type of public key for read-only access? That way I (the provider of photos) don't have to login every time?
The Google Photos Library API is used via OAuth2 user authentication. All requests through the API are made on behalf of a user. Public API keys or service accounts are not supported.
OAuth tokens expire after a certain time, which is returned as part of the OAuth authentication request. You can use a refresh token to retrieve a new access token once it has expired. If you'd like to do this without explicit interactive user interaction, your application needs to be authorized for offline access. The good news is that the authentication client libraries handle this for you.
If you are using Google Sign-In (for example on Android), you can check if the user has already signed in using GoogleSignIn.getLastSignedInAccount(this), so you would not need to prompt again for access. You could also enable server-side access if you want to make these offline requests from your backend.
If you are using any of the Google OAuth client libraries, you can specify the 'offline' parameter as part of the initial sign-in request. For example in Java, you would set the access type: .setAccessType("offline") on the GoogleAuthorizationCodeFlow.Builder during creation.
Below is my understanding of the process of oauth2.0(using google as the oauth2.0 server)
my customer click 'login with google account' button on client side.
the browser redirect to google's login page.
my customer inputs it's credential and click 'login'.
if my customer succeeded in previous step,the browser will redirect to my server's url
(www.[myserver].com/auth/google/callback) with some extra query
data.
then my server will do some work to get some token from google and finally get my customer's information.
My question comes from the next step. I want to use token based authentication.Then I have to make my customer to store my own token in localStorage. I can't figure out how to achieve this in the 6th step(how to send a new token to client side and store it in localStorage?).
(I know that every thing will be easy if I am using cookie-based authentication. because I can just utilize 'set-cookie' in the 6th step, and the client side will be easily store the credential data in client side's cookie)
Google APIs use the OAuth 2.0 protocol for authentication and authorization. Google supports common OAuth 2.0 scenarios such as those for web server, installed, and client-side applications.
I figure out that I can use some type of template engine on my server side(just like discussed here). So I can render my template file using variable before send it to my customer.
I'm setting up an HTML5 and JavaScript web application to consume Azure Mobile Services tables using the JavaScript client library. I've managed to get authentication setup successfully with the MicrosoftAccount identity provider. On load, my application checks if the user is already logged in, or if we have a token and username stored locally. If true, I hide the login button, and display the logout button, and proceed to load application data.
My problem is that when a token that is stored locally expires, my application still thinks the user is logged in. Therefore when I request table data, I get a 401 Unauthorized HTTP response.
Is there a graceful pattern to renew an expired token without burdening the user with relogging in every time their token expires?
You will need to log the user in every time, unfortunately. The token must have a lifetime associated with it. On some client platforms, you can get much longer lifetimes via single-sign flows, but these are generally not available for HTML. The common pattern is to, upon receiving the 401, retrigger your login code. Here is a blog post showing the approach for the Mobile Services Managed SDK. The same concepts should apply for JS.
