**Description** Current Android SDK provides two ways to login to zoom account: email/password and SSO token. There’s little document regarding how SSO token works. I tried to use Zoom REST API to complete OAuth flow, and get a so called “toke” via “[https://api.zoom.us/v2/users/me/token](https://api.zoom.us/v2/users/me/token)”. But sdk.loginWithSSOToken() does not seem to accept that token. I also tried to feed in access token directly, which does not work, either. So my question is, is there any way in Android SDK to login without using email and password? The ideal flow is to use same user interface that Zoom app uses, where user can choose to enter email / password or use OAuth such as Google account to login. **Which version?** Android SDK [v4.3.1.47200.0322](https://github.com/zoom/zoom-sdk-android/releases/tag/v4.3.1.47200.0322) Thank you! -Jiulong ---

Hi Jiulong, Thanks for the post. The token that the loginWithSSOToken is expected is different from the token you retrieved from the Zoom API. - The token for the loginWithSSOToken is from the SSO service provider. If you would like to know more: [https://support.zoom.us/hc/en-us/sections/200305453-Single-Sign-On](https://support.zoom.us/hc/en-us/sections/200305453-Single-Sign-On) - The token you retrieved from the API is the Zoom API tokens, you can use these tokens to start a meeting without using email and password. The detailed info regarding this is mentioned by Fred. Hope this helps. Thanks! ---

Hi @carson.zoom @Fred_Luo , Seems like I need to use StartMeetingParamsWithoutLogin with token and ZAK. However this params requires a scheduled meeting number as described in the document. Is there similar options (use token and zak) for instant meeting? Or is the meeting number optional I can simply put a null string? Thanks, -Jiulong ---
