Describe the problem
In the settings, the "Link accounts that use the same email" option is enabled.
After creating a new user via a server firebase function, a new user is created without any provider. I use this code in the function when sending an invite.
Additionally, my project has several providers enabled, such as the Microsoft provider. After logging in through it, I get the following error: auth/account-exists-with-different-credential As a result, the newly invited user cannot immediately log into the system through any provider.
I expect that I should be able to log into the system through any provider since the user is new and does not have any associated provider.
Steps and code to reproduce issue
admin_function.js
exports.sendInvite = onCall({ secrets: [sendgridApiKey], enforceAppCheck: true }, async ({ data, auth }) => {
await getAuth().createUser({ email: data.email });
.....
})
Client App
const instanceProvider = new OAuthProvider('microsoft.com');
instanceProvider.setCustomParameters({ prompt: 'select_account' });
const result = await signInWithPopup(auth, instanceProvider);
