Hey @krishnasahudev

Thanks for using the dev forum!

What 2FA did you use?

Thanks!

Hey @krishnasahudev

I don’t think the 2FA should impact the SDK’s behavior directly since it is not a part of the SDK. Is it possible the 2FA is not working correctly?

Thanks!  
Michael

I do not know about this @Michael_Condon.  
And there is not documentation on [zoom ionic sdk](https://github.com/zoom/zoom-sdk-ionic) page to incorporate 2FA authentication type in the app.

Is it reproducible on your end as well?

I need some resolution for the users who have enabled 2FA.  
Let me know what i can do to enable 2FA verification in ionic app.
