Microsoft

Enabling OAuth with Microsoft Azure Entra ID (formerly Active Directory) allows your users to sign in and sign up to your application with their Microsoft account.

import { betterAuth } from "better-auth"
 
export const auth = betterAuth({
    socialProviders: { 
        microsoft: { 
            clientId: process.env.MICROSOFT_CLIENT_ID as string, 
            clientSecret: process.env.MICROSOFT_CLIENT_SECRET as string, 
        }, 
    }, 
})

Signin with Microsoft

To signin with Microsoft, you can use the signIn.social function provided by the client. The signIn function takes an object with the following properties:

• provider: The provider to use. It should be set to microsoft.

import { createAuthClient } from "better-auth/client"
 
const client = createAuthClient()
 
const signin = async () => {
    const data = await client.signIn.social({
        provider: "microsoft",
        callbackURL: "/dashboard" //the url to redirect to after the signin
    })
}
