Login Button not working in MS Teams

Posted on by pankajrai Microsoft Employee

I am able to configure user authentication and retrieve user's information via flow using graph APIs.

Solution works fine if I use the bot in a browser. I click on login and i get logged in.

However if the bot is called using MS team, the Login button does nothing.

it is simply stuck at following windows. Nothing happens when I click Login

I referred to https://docs.microsoft.com/en-us/power-virtual-agents/publication-add-bot-to-microsoft-teams

and added token.botframework.com under the Valid domains section but still not help.

Any suggestions ?

"when the user receives and click on the button inside the MS Teams"

The problem is that the button inside MS Teams does not show up, so the user can't click it.

@IgorCurl did you find a solution?

I will make another post about this because I am using CoPilot Studio (not PVA) but experiencing the same problem.

Re: Login Button not working in MS Teams

Hi,
I still have this issue. When Teams Channel is enabled, and authentication is SSO, and we use Sharepoint website the issue occurs. If SharePoint is not used, user is not asked to authenticate. Issue is that Login button does not appear in Teams chat. Same result if we import the app as .zip or install it from the app store.

I think we can consider this as resolved as PVA now as more Teams integration and Login happens automatically.

I am also having this issue... The prompt to authenticate appears in teams but the login button is missing, therefore, the user is unable to proceed further. It is as if the adaptive card for login isn't working in teams (it works fine in the test web bot in PVA.

Has anyone else experienced this?

Hi @pankajrai ,

In the right way, when you use the Authentication action you can configure the next steps after this action inside the topic, and when the user receives and click on the button inside the MS Teams, automatically will continue the way if logged successfully.

Re: Login Button not working in MS Teams

Hi @pankajrai ,

You can see this part of the documentation inside the Authentication post:
"Once the user enters their username and password in the prompt (hosted by the identity provider), they might be prompted to enter a validation code, depending on the channel. Some channels, such as Microsoft Teams, do not require the user to enter a validation code."

Basically, when you click on the button, you chatbot recognize the authentication automatically.
