**Description** I get MobileRTCAuthError\_KeyOrSecretWrong in my AppDelegate onMobileRTCAuthReturn method when trying to authorize my app. I’ve already double-checked that the key and secret match what is in our marketplace SDK app and that that app is activated. We had been using this successfully in previous versions, I do not know when it broke. **Which version?** v4.6.21666.0428 **To Reproduce(If applicable)** 1. Happens on launch of the app **Smartphone (please complete the following information):** - Device: iPhone 8 - OS: iOS13.3 - Version 1 **Additional context** This is the main way we try to authenticate in AppDelegate: ``` let zoomContext = MobileRTCSDKInitContext() zoomContext.domain = "https://www.zoom.us/" MobileRTC.shared().initialize(zoomContext) if let service = MobileRTC.shared().getAuthService() { service.delegate = self service.clientKey = kZoomSdkKey service.clientSecret = kZoomSdkSecret service.sdkAuth() } ``` I’ve also tried setting the domain to “[zoom.us/](http://zoom.us/)”, but see the same behaviour. I’ve tried setting the jwt token, but then I don’t see the onMobileRTCAuthReturn method called at all. ---

We just started experiencing the exact same issue today. Our app had been authenticating perfectly fine, but now we’re receiving the MobileRTCAuthError\_KeyOrSecretWrong error. Our keys and secrets are definitely correct and our app is activated. We’re also using the [zoom.us](http://zoom.us) domain. Any feedback/guidance on this would be greatly appreciated. This is a major inconvenience for our users. ---

We need to create an sdk app, and not a jwt app as stated in doc. 😡 🤬 ---

Hi @carson. We were using the credentials from a jwt app, as stated in doc. But for the sdk to authenticate you must use the credentials from a sdk app. I think it’s better to fix the doc. Bye ---

Hi @devark, Thanks for the reply. Could you provide the link of the doc that needs to fix? I will forward it to the doc team to fix it. Thanks! ---
