How to let users login with Twitter AND Facebook (Firebase/Firefeed) - twitter

I am working with the Firefeed app (based on Firebase) and I am wondering how I can give users the option to both login with Facebook and Twitter.
I correctly set-up my firebase but I guess the issue is that I either use
authClient.login("facebook");
or
authClient.login("twitter");
How can use both to give them the choice? I know, its probably a beginner questions. :)
Many thanks!

I'm not quite sure what you're looking for here. If you want to allow people to log in with either option, then you can simply have 2 buttons, one that says "Log in with Twitter" and one that says "Log in with Facebook".
If you want to have an account system that merges multiple social accounts into a single account on your system, so that users could log in with either system and access the same data, this is a little more complex. There's a thorough answer here:
How can I login with multiple social services with Firebase?

Simultaneously "Add to Slack" and "Sign in with Slack"

I'm working on a Slack app that also links with a web app, which users can log into using Slack. It's very common for a new user to need to both log into the web app and add the app to Slack.
I'd like to let them do this with a single trip through OAuth. Since the web app needs a name, email address, and profile picture for each user, I added the "identity.basic", "identity.email", etc. scopes to the ones requested by the "Add to Slack" button. But it turns out that Slack doesn't allow this. The Slack OAuth page says "Invalid permissions requested: Cannot request both identity scopes and other scopes at the same time".
One alternative might be to request the users:read and users:read.email scopes instead of the identity scopes. But this gives our app more access than it needs; it just needs the info for the current user, not for all users on the team. (It might later need that info for all users, so I'm considering doing this anyway, but I'm not sure if users would like it.)
The other alternative seems to be to make the user go through two different OAuth permissions screens. But this seems cumbersome and not a good user experience.
So the questions are (1) is there a better way, and (2) why doesn't Slack allow combining the identity scopes with others?
UPDATE to clarify, in response to the answer from #erik-kalkoken:
I'm aware of the differences between "Add to Slack" and "Sign In with Slack". I certainly don't intend to take away the option for most users to do a simple "Sign In with Slack". However, with this particular app, it makes no sense to do "Add to Slack" without also being signed in to the web app. This needs to be done by one person per Slack team before other users on that team can use it. Our onboarding process for new teams is a bit cumbersome, and I'm looking for ways to make it simpler and smoother. Since the sign-in and add steps could theoretically be combined into one step, I would prefer to do that.
Part of this may be because we aren't developing a "Slack app"; we're developing a Slack integration for a web app. The web app can be used without using Slack, and has its own concepts of users and communities.
The "better way" in my opinion would be to not combine these two functions on your website, because their effect is very different. I would argue that it would be confusing to users if they are combined and would not make a good user experience.
"Add to Slack" is installing a Slack app for the whole Slack team. You only do this once and its usually done by the admin of a Slack team.
"Sign in with Slack" is used to authenticate any user of a Slack team. You would use this function every time you log into your app and its used by many users of a Slack team.

Multiple social login options on iOS

I am creating an app with multiple login options.
There will be a possibility to login via Facebook, Google+, and a manual login.
Its all good for now. But lets talk about the case where a user decided to logout from one account, and login using the other account. For instance, logging in via Facebook, logging out, then logging in via Google+.
This scenario causes the database to create multiple users in the database for only one user.
The only way I can think of solving this, is to find a link between all the different logins.
Options:
Email - The user can use different emails for the different apps, or might not have his email public through one of the social apis.
Phone Identifier - The user might let someone else use the app on his phone, or the user might have multiple devices.
Name - There will be many people with identical names.
Due to the above not being viable options, I wanted to see how other people have approached this concern.
I am not looking to use any 3rd party frameworks.
Thanks!

Google+ Sign-In - stop requesting people you're connected with

Is there a way to make the Google+ Sign-In not request the user's "list of people you're connected to on Google+"?
My goal is to use the G+ sign in for authentication purposes today, and in the future also use it for social sharing functionality. As the owner/operator of the service requesting sign in I don't care who is in a user's circles.
Is it possible to remove the request for all of the people a user is connected with? Am I missing something with this? For example if I didn't request all of a user's connected people would the user no longer be able to share to them?
I'm aware of the Google OpenId sign in functionality, but it doesn't provide the functionality I'd like for the future.
Whenever you use the Google+ sign-in button, the scope plus.login is added. As such, it will request the "know who you are on Google+" and "List of people you are connected with". A few notes on this:
The user has control over which people they share with you so if they don't want to share this information, it's within their control.
If you're interested in the information in the future - using the existing connections people have is a great way to make your site better - the access will be available to you.
If you still feel you should be able to just request the user's profile, please add a star/feature request to the issue tracker here:
https://developers.google.com/+/
The more information regarding why you want to do this and the clearer your request explanation, the better!

Can we add Twitter permissions on demand in an iOS app?

We are making an iOS app that has two points of integration with Twitter:
1. User can use Twitter account to login (or FB account or just email/password)
2. User can share his freshly done work to twitter (just post a tweet)
So for some users we need a read/write access to twitter, but for some only minimal permission for loggin in would be enough and I wouldn't like to scare users away by asking for a write permission on the first login, when they might not even realize the app can share their work to Twitter.
Is it somehow possible to request only login permissions on first start and tweeting permission only on a first Tweeting need?
P.S.
We are not going to use the built-in iOS sharing sheets, because they are good only for sharing to either FB OR Twitter OR elsewhere. We want to offer sharing to Twitter, Facebook, Email and maybe somewhere else simultaneously, in a foursquare app style
I'm not familiar with the recent changes, but I believe that the permission is the one you set in https://dev.twitter.com/apps. So no, you can't do it. I don't think you can do that on facebook as well.
(sidebar: twitter's documentation now is complete mess. I can't find any useful information there)

Integration With Facebook

I've never used the FaceBook SDK before so I'm not sure what I should be using or whether what I'm thinking of can actually be done. But I want to try to integrate some Facebook functionality with my ASP.NET MVC3 application.
What I need to do:
I want to be able to access someone's Facebook account (granted their permission) and allow them to send out invitations to my website. But, when a friend clicks on the link in the invitation message (whether a wall post, PM... whatever), follows through and registers on the site, I want to be able to track that (maybe by appending the ID or username of the this user to the invitation link, and then extract it from the query string when the invited person/friend registers).
Questions:
From what I've read so far and according to this link, what I think I should be using is the Facebook Connect API. Am I right?
Is what I'm trying to achieve actually doable? Basically, can I append the username to the invitation link? Is Facebook okey with that?
Do you have any good resources other than the Facebook Developer Wiki? Share them please!
P.S: I do not want users to login to my website using their Facebook account. I have my own Membership system. I just want to allow them to invite their friends to register at my website and track that. More requirements might arise but for now that is all what I need.
Your help is appreciated!
EDIT:
Ok I went ahead and created some test app using the Developer FB app to do some experiments. One thing I do not understand though...
Canvas Page: The base URL of your app on Facebook.
Canvas URL: Facebook pulls the content for your app's canvas pages from this base URL.
So what exactly is the Canvas URL? From what I understand, it's a URL to a resource (page?) on my website which Facebook can display inside the Canvas Page, is that correct?
yes
Yes
Facebook documentation + facebook developers forum, that should be all for you. Also, as you are using asp.net mvc, facebooksdk discussion will help you also if you use that library. I will stringly recommend to use that library.
Also, it seems, you are a beginner on facebook api with c#. If so, you can consider my blog post for beginners on facebook open graph api tutorial in c#. There also some other related posts also.Hope you may like them.
Let me know if you wanted to know something else also specifically.
Yes
Yes
Nope. The Developer Wiki has its issues but the Facebook Docs usually solve your problems.
