Question

Can we join Teams meeting in web browser by using a valid access toekn and not entering any login credentials manually

Ramashankar Agrahari 31

Hi,

My objective is to join a Teams meeting on a web browser (say chrome) where user need not to enter his credentials manually.

To achieve this, User's access token is fetched programmatically by using Microsoft Graph API and stored in a server pc safely.
So now, how can I utilize that access token to open meeting url such that user joins the meeting directly, without entering credentials?

Is it technically feasible?
Is there any such mechanism in which I pass this access token in url or in header so that Teams recognize it?

Thanks.

@Ramashankar Agrahari Are you trying to build a recording bot that can join meetings authenticated?

Not its not the recording bot. I want that one of the real participant should join the meeting automatically just by clicking on the meeting url.
Look, if as a user I click on a team meeting url in my email, then it gets opened in web browser automatically, where it first tries to launch the meeting using Teams' desktop client app. But if desktop app is not installed, it gives option to open the meeting in bowser itself. On browser it then asks user to sign-in (assuming user has never signed-in Microsoft account in that browser). Once user login, team meeting is opened with his/her account.
What I want is that how to bypass this sign-in step, or how I can get it authenticated in any other way where user need not to type anything (credentials) manually in the browser.
I can get an access token/refresh token for that user programmatically using Graph API, but I am unable to use that token to get join meeting automatically.

Hi Prasad,
When user opens a team meeting url in web-browser, then if user has already signed-in to his Microsoft account in that browser, then it automatically log-in user to meeting without asking his credentials again.
So I wanted to know how this process work. Certainly the url/web-page is fetching some tokens or any other info from browser cache/local storage through which it get ensured that user has already signed-in into his Microsoft account. So can I utilize same mechanism in anyway.
I am not trying to do any security hacks but just trying to automate login steps to give user a smooth meeting-joining experience using my custom app.
Thanks,
