Thanks Tommy. By authentication I meant ‘sign in to zoom’ option and not the manual or auto approval flow. Can you please confirm the correctness of the attached table ? Do you have any plans or ETA for adding the unsupported combinations in the future releases ? ---

Hey @priyavarshini.muruga , Gotcha, currently joining Authenticated Webinars is not supported with the Web Client SDK, but you can join Authenticated Meetings: > **[Joining Authenticated Meetings - Advanced Guides - Web - Client SDKs - Zoom...](https://marketplace.zoom.us/docs/sdk/native-sdks/web/advanced/joining-authenticated-meetings)** > > Joining Authenticated Meetings > > When using the Web SDK, meeting hosts can require their participants to authenticate either through Single-Sign On (SSO)...

Hello @tommy > [@tommy](#): > > However, the Client Web SDK does support Webinars that have registration to auto approve: Just to be sure: this is only true for webinars but not for meetings? Thanks David ---
