Instagram oAuth login with Facebook account - ruby

I'm trying to build a connection to the Instagram API using the instagram-oauth gem. However, when I open the oauth url, I'm not able to log into my Instagram account via Facebook. Only username/password is shown. Do I have to activate Facebook login support?

Instagram's API requires OAuth 2.0 and it does not support logging in to Instagram with Facebook. OAuth launches the Instagram login via a prebuilt, un-editable web browser, so this functionality is not possible at this point in time.

Google Play Console : Provide instructions for app access

I have developed an app that is using Auth APIs of Facebook and Gmail. as you know we don't need any email password to login just click on facebook or gmail button and auth API generates authentication token to login into app.
So I am submitting that app on playstore but they are rejecting and asking for login credentials. I have provided them my gmail account login credentials but they using those credentials to login into facebook account and rejected my app again.
what I should do to avoid rejection again?

How can I log in using Google OAuth in the TikTok in-app browser?

When attempting to log in with Google OAuth via the TikTok in-app browser it says "Authorization Error Error 403 disallowed_useragent Google can't sign you in safely inside this app. You can use Google sign-in by visiting this app's website in a browser like Safari or Chrome."
Thinking this is either a call by Google to prevent login within TikTok or they simply haven't added this user agent yet.
Google OAuth does not work in embedded web views per policy. See https://developers.googleblog.com/2016/08/modernizing-oauth-interactions-in-native-apps.html.
You should reach out to the app developer to recommend they use one of the alternatives recommended like Chrome Custom Tabs.

Identityserver4 setup for native mobile app with custom and social login

Trying to get my head around the Identityerver4 setup for my project. I have a mobile app where users should be able to login with either facebook or username/password. Facebook login is implemented using the native facebook if available on the device. This results in a token from facebook. With this token I want to request an access_token and refreshtoken (hybrid flow) to access my api (resource). At the same time, some users will also log in unsing username and password.
As I need some info about the user, my plan is to user ASPNET Identity but I'm not sure how to make it wotk together with IdentityServer and If user profiles should be created in Identity based on both logins (registration). It seems obvious for the username/password login, but what about my social facebook login. Later there might also be a web client. So my basic question is how to handle the user registration with both setups

How to make a 'log in with Spotify' authentication system using Firebase?

I have a web page which I want to make it only available to users after they log-in using their Spotify account. I am using Firebase for backend.
I haven't implemented any social authentication before, so an in-depth answer will be much appreciated.
There is a great exemple to implement Firebase auth with Instagram Oauth. It will be exactly the same for Spotify.
Read it here : Authenticate your Firebase users with Instagram
edit: And now there is also a sample for auth with Spotify + Firebase functions
