MicrosoftStrategy for Remix using Remix-Auth
The Microsoft strategy is used to authenticate users against an account on Microsoft Active Directory using Remix-Auth. This can be a work/school account or a personal Microsoft account, like Skype, Xbox and Outlook.com. It extends the OAuth2Strategy.

Follow the steps on the Microsoft documentation to create a new App Registration. You should select Web as the platform, configure a Redirect URI and add a client secret.
If you want to support login with both personal Microsoft accounts and school/work accounts, you might need to configure the supported account types by editing the manifest file. Set `signInAudience` value to `MicrosoftADandPersonalMicrosoftAccount` to allow login also with personal accounts.
Change your redirect URI to https://example.com/auth/microsoft/callback
or http://localhost:4200/auth/microsoft/callback
if you run it locally.
Be sure to copy the client secret, redirect URI, Tenant ID and the Application (client) ID (under Overview) because you will need them later.
npm install remix-auth-microsoft remix-auth remix-auth-oauth2
// app/services/auth.server.ts
import { MicrosoftStrategy } from "remix-auth-microsoft";
import { Authenticator } from "remix-auth";
import { sessionStorage } from "~/services/session.server";
export let authenticator = new Authenticator<User>(sessionStorage); //User is a custom user types you can define as you want
let microsoftStrategy = new MicrosoftStrategy(
{
clientId: "YOUR_CLIENT_ID",
clientSecret: "YOUR_CLIENT_SECRET",
redirectUri: "https://example.com/auth/microsoft/callback",
tenantId: "YOUR_TENANT_ID", // optional - necessary for organization without multitenant (see below)
scope: "openid profile email", // optional
prompt: "login", // optional
},
async ({ accessToken, extraParams, profile }) => {
// Here you can fetch the user from database or return a user object based on profile
// return {profile}
// The returned object is stored in the session storage you are using by the authenticator
// If you're using cookieSessionStorage, be aware that cookies have a size limit of 4kb
// For example this won't work
// return {accessToken, extraParams, profile}
return User.findOrCreate({ email: profile.emails[0].value });
}
);
authenticator.use(microsoftStrategy);
See Microsoft docs for more information on scope
and prompt
parameters.
If you want to allow login only for users from a single organization, you should add the tenantId
attribute to the configuration passed to MicrosoftStrategy
.
The value of tenantId
should be the Directory (tenant) ID found under Overview in your App Registration page.
You must also select Accounts in this organizational directory as Supported account types in your App Registration.
