incorrect SDK key & secret would introduce error code 5, please make sure use the correct SDK key & secret. Refer to&nbsp;[https://developer.zoom.us/docs/ios/](https://developer.zoom.us/docs/ios/)

Getting the same error code 5 with JWT on iOS, not sure what does this means

```
func authenticateSDK(token: String) {
let authService = MobileRTC.shared().getAuthService()
if let authService = authService {
  authService.delegate = self
  authService.jwtToken = token
  authService.sdkAuth()
}

```

}

but it works with client key and client secret

```
func authenticateSDK(token: String) {
let authService = MobileRTC.shared().getAuthService()
let clientKey = "some key"
let clientSecret = "some secret"
if let authService = authService {
  authService.delegate = self
  authService.clientKey = clientKey
  authService.clientSecret = clientSecret
  authService.sdkAuth()
}

```

}

this is how we generate JWT on Node.js

```
const now = new Date(Date.now());
// expires in 2 hours
const expiresIn = new Date(now).setHours(now.getHours() + 8);
const payload = {
  appKey: config.zoom.sdkKey,
  iat: now.getTime(),
  exp: expiresIn,
  tokenExp: now.getTime() + 3000,
};
const token = jwt.sign(payload, config.zoom.sdkSecret);
```

Hi @micepadapp,

Thanks for the reply and the code snippet. The codes are correct but there is an issue with the JWT token that is generated by JavaScript:

Per [Date.prototype.getTime() - JavaScript | MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/getTime),

> JavaScript uses _milliseconds_ as the unit of measurement, whereas Unix Time is in _seconds._

The regular JWT token requires the timestamps in seconds, so if you pass the timestamp you got from Date.now().getTime(), the timestamp will be invalid(Something like 50 thousand years later). Please try to convert the timestamp in seconds.

Thanks!
