ClaimsPrincipal Azure Bot Framework

This is a generalized concept question concerning obtaining information of the user in the bot chat. Preferably this would be through OpenID and to start with using Microsoft Accounts. We would want to be able to read User Display Name, User Email address, User Group Membership, etc. What is the best way to obtain this information in Azure Bot Framework? In MVC using OpenID to obtain ClaimsPrincipal is easy, but can this concept be used in Azure Bot Framework and are there any examples of this process?
There was a lot that went into this, but essentially I used an OAuth Connection on the Bot service to send the user to AADv2 endpoint to obtain the token. I then used that token to send to the GraphServiceClient method (part of Nuget package Microsoft.Graph) to obtain User information. This was granted by giving the app in Azure AD MS Graph User.Read API permissions.

OAuth or API key authorization?

I'm trining to create live stream on youtube using google API. Now it working only when I use oauth authorisation. When I use API key authorisation I get authorisation error (login required)
When I use oauth authorisation - it require to enter confirmation code each time I create new translation. Is it possible to use "liveStreams->insert" method of API with authorisation that does not require entering of confirmation code?
From what you are writing it appears to me that you haven't understood the concept of OAuth and when to use OAuth vs an API key.
Try to think about it this way: You, as a person, have a Google account. This Google account is not the same as your YouTube account (or, as it is more commonly refered to, your YouTube channel). But your Google account is associated with your YouTube channel (of which you can have multiple). Because you are logged in to your Google account and your channel and Google account are linked, the YouTube website knows who you are and gives you access to your channel.
Now you head over to the Google Cloud Console. Here you create a project, which is very similar to a YouTube account in the sense that it, too, is an independent account which in this case represents your app, but is linked to your Google account so the Cloud Console website knows to give you access to the project as long as you are logged-in to your Google account.
HOWEVER, your YouTube account is not linked to your Cloud Console project. When you make an API request with an API key, the API does not see you as in "your Google account", but rather your apps's Cloud Console Project. That's why with an API key, you can only access publicly available data (everything you could "see" when you browse YouTube while not being logged-in).
So, in order for an application to read private channel information or modify channel information, the API needs verification that whoever makes that request is actually allowed to do that. This is where OAuth comes into play.
When you say you have to provide the confirmation code for each request, I think you don't save the access token and refresh token. I highly recommend you read Using OAuth 2.0 to Access Google APIs and Obtaining authorization credentials over on Google Developers to help get you started.

send emails from MY gmail account with OAuth2 and nodemailer

I want to send emails from my gmail address through my own server. I'm using nodemailer and using account credentials is flaky, and often times doesn't work and leads to this thread
I've implemented everything on that thread many times, and still it's flaky, and also I know OAuth2 is the way to go.
I have a project with cliendID and clientSecret in google developer console, as you can see:
But how do I get an access token WITHOUT any browser interaction?
I seem to be missing something trivial here ...
I've went through all google tutorials and docs I could find about OAuth2, tokens, and APIs, but all guides go through the browser in one point.
Go to the OAuth Playground, click the cog on the top right, check the Use your own OAuth credentials and insert your clientID and clientSecret.
Then select the Gmail API v1 scopes you want in the list to the left and follow the outlined steps and you will get an access_token and a refresh_token.
Google Oauth2 actually all Oauth2 implementations I am aware of require that a user grant an application access via a web browser.
There is an alternative type called service accounts this is more like oauth1 service accounts are preauthorized. You can grant a service account access to your google drive by sharing folders and files with the service account like you would any other user. Because they are preauthorized there is no browser window pop up with service accounts.
You can only user service accounts with Gmail if you have a Google domains account Gsuite. The admin can go in and grant the service account access to the Gmail account in question. Perform G Suite Domain-Wide Delegation of Authority
If this is a normal user Gmail account you cant use a service account. You will have to use Oauth2 popup the request and save the refresh token so that you can gain access at a later date.

Google API: one authenticated user for all

I need to read/insert events into a specific calendar, using Google API. All registered users (in my app) can read and insert events into the calendar. I don't have to authenticate each user with OAuth 2.0, because the app will not read the user data - only specific account data.
I'm a professor and all my students can read and insert in my calendar. So, they do not need to login (Google Account) to do it, because it's a single account's data.
Is there a way to set a unique key for the main account?
OAuth2 doesn't makes me sense.
Maybe you need a service account here. It is an account that belongs to your application instead of to an individual end-user. Your application calls Google APIs on behalf of the service account, and user consent is not required. (In non-service-account scenarios, your application calls Google APIs on behalf of end-users, and user consent is sometimes required.)
The Calendar API can use the Delegating domain-wide authority to the service account. For example, an application that uses the Google Calendar API to add events to the calendars of all users in a Google Apps domain would use a service account to access the Google Calendar API on behalf of users.

Using Multiple Google API services independently

I'm working with 3 Google API Services(Analytics, Webmasters, PageSpeed). I have a single Google API client ID(with all 3 services activated) and common Google API PHP SDK in my server.
User of this aplication should be able to grant and revoke access for each service independently at any point of time depending on his usage. Is this possible?
Testcase:
If user wants to use only analytics service initially, he should be able to grant access for only analytics and later if he wants to use pagespeed service also, he should be able to grant for pagespeed also without compromising access for analytics. If he wants to use analytics & webmasters later, he should be able to revoke only pagespeed access without compromising the access for analytics or webmasters.
When you request an access token, you specify the resources you want access to. If later you need to access another resource, you request another token for that resource.
You can simplify your implementation by setting the include_granted_scopes to true when requesting the token. This will include all previous authorizations so you only need to deal with the new token.
AFAIK there's no way to revoke access to specific scopes, even though the documentation mentions that "When you revoke a token which represents a combined authorization, all of the authorizations are revoked simultaneously;". This actually happens even when revoking individual tokens. Also, the Google account user interface does not allow the user to specify which permissions he wants to keep, it's only possible to revoke all access from an application.
See the docs for incremental authorization.
