How can we bypass salesforce login screen for authentication by custom login screen?

We need authentication functionality without using salesforce login page, we need our own custom page for login​
As facebook provide option for authentication by using their own button or we can also use their function over our custom button
Note: we are using salesforce mobilesdk and application is based on reactnative.
If you are integrating Salesforce Mobile SDK then salesforce won't encourage you to access their features without making secure checks.
Mobile SDK includes a complete implementation of Salesforce Connected App Policy, so that all users can access their data securely and easily. It supports SAML and advanced authentication flows so that administrators always have full control over data access.
Below are the major features of SDK which salesforce provide after their authentication.
=> SmartStore Encrypted Database
=> Mobile Sync
=> Mobile Services
=> Salesforce Communities
When you create a native app using the forceios utility, your project starts as a fully functioning app. This app lets you log in to a Salesforce org, and then it displays live Salesforce data.
So it's not possible to skip login screen when using Salesforce Mobile SDK.

Is it possible to integrate the Facebook login without using the iOS SDK?

Currently i am using the Facebook SDK to implement the Facebook login to our native iOS application. For this i am using the native iOS SDK for Facebook. This application is both for mobile and web, so is it possible to integrate Facebook login without using the SDK from application side. I mean authentication done fully through API and server side.
Please have a suggestion.
I referred to a SO link:
Design for Facebook authentication in an iOS app that also accesses a secured web service
Sure! You can always use their API directly, which essentially is the same as they do with the SDK.
Check out the documentation on the following link.

Native azure login iOS

I am developing an iOS app and want to implement an Azure B2C login without redirect to a WEB UI, only native using the username and password, facebook or google. How can i do this? It is possible?
You can use Azure Mobile Apps and authentication by social media (fb, tt, gmail, MS account) or enterprise via Azure Active Directory.

Gmail API 0Auth 2.0 using OAuth Phonegap SDK

Has anyone had success in using the Gmail API's authorization in a Phonegap application? I found this (http://phonegap-tips.com/articles/google-api-oauth-with-phonegaps-inappbrowser.html) that describes using the generic Google API OAuth with Phonegap's inappbrowser plugin, but the newly released Gmail API does OAuth authorization differently, and I'm not sure how to get it to work with Phonegap.
Note: It does work when I try a web version of my app, but the button that brings up the authorization screen doesn't do anything in Phonegap..not sure why. I do have the appropriate Android credentials for the app in the Google Developer's Console.
UPDATE: Using OAuth's Phonegap SDK (found after registering your app here: https://oauth.io/), I am able to authenticate a Google Account. However, I am unsure how to then call Gmail API methods or correctly pass whatever authentication tokens from the OAuth SDK to any Gmail API code. Has anyone done this and can share their knowledge?
I found a solution using the OAuthio Phonegap SDK. Then I can call the appropriate HTTPS requests from the Gmail API.
If you want to login your users via Google on iOS and Android, then use this new plugin I just created: https://github.com/EddyVerbruggen/cordova-plugin-googleplus
You will also receive the name and gender etc from the plugin. The plugin will also try SSO with any other Google apps installed on your device by using the Google+ SDK on both platforms.

To develop a lib with SSO on twitter

I want to develop a lib for twitter which can achieve SSO and can display the name of app which uses this lib during APP authorization.
I know you can do this in apple using twitter framework, but I want to do this in Non-Apple platforms.
Any ideas please?
You could do this leveraging the OAuth capabilities available from Twitter. You could leverage a user's Web session if they are already signed in to twitter.com. See: https://dev.twitter.com/docs/auth
Any native (mobile) application SSO capabilities would depend on what the Twitter native application makes available. I'm not aware of any - but Facebook does offer such features: https://www.facebook.com/help/mobile/singlesignon
