@sagesurfertest18 , Thanks for the clarification, login with username and email does not work with v5. 9 . You will have to use OAuth on 5.9. If you want to still leverage username and email, I can provide a link to version 5.4v. However, you will have to update to 5.9v in Nov. I’ve linked support documentation below for your reference: > **[PKCE OAuth tutorial](https://marketplace.zoom.us/docs/sdk/native-sdks/android/build-an-app/pkce/)** > > The Zoom Developer Platform is an open platform that allows third-party developers to build applications and integrations upon Zoom’s video-first unified communications platform. ---

Hello Donte, I am using the current version 5.7.6 and the latest version is v5.11.3.7251. If I update the version to the latest one then will my issue be resolved? Looking forward to your reply. Thanks and regards, Rahul Maske ---

@sagesurfertest18 , You should still be able to use username/email login with V5.7.6. However, you will have to upgrade to the latest version in November. For the latest version of the SDK, you will have to add support for authorization and authentication using OAuth 2.0. ---

Hi @donte.zoom , Will we be able to still use direct login using v4.6.2? Seems only working for paid accounts only. Still returning a result of error 407. Thank you. ---

@joseph.m, Yes, v4.6.2 supports Username/Email login. To clarify, are you saying that you can only successfully login with paid accounts when using v 4.6.2 ? ---

Hello Donte, I am upgrading the SDK to the latest version to v5.11.3.7251 and after upgrading the SDK Can I use server to server authentication? And if I will be able to use server to server then can you provide me with some sample applications where I could get the details code for starting meetings and joining meetings. Thanks and regards, Rahul Maske ---

@vishalwadekar766, You will need to upgrade to either 5.4 or the latest version of the SDK and 5.3 and below have End of Life. I can share a link to 5.4 and you can find the versions 5.7 and above in the Zoom Marketplace. ---

@sagesurfertest18 For Andriod, you will want to implement PCKE OAuth flow and you can find example code here : > **[PKCE OAuth tutorial](https://marketplace.zoom.us/docs/sdk/native-sdks/android/build-an-app/pkce/)** > > The Zoom Developer Platform is an open platform that allows third-party developers to build applications and integrations upon Zoom’s video-first unified communications platform. ---

Hi @donte.zoom , Can you help us walkthrough with the update? We’re having problems using PKCE OAuth since it only gives ZAK for licensed account only. Can you confirm if this is true? Thank you. ---

@joseph.m, You should be able to get the ZAK for non-licensed accounts. What response are you getting when attempting to get the user’s ZAK token?

Thank you for this @donte.zoom . Do we have to change our SDK type from user-managed to account level to authenticate non-licensed users? ---

@joseph.m It looks like you are trying to install a non-published app outside of the account. To fix this, you must [publish the app](https://marketplace.zoom.us/docs/guides/publishing) to the [Zoom App Marketplace](http://marketplace.zoom.us/). If you are looking to test your app externally before publishing it, you can request a [publishable url](https://marketplace.zoom.us/docs/guides/publishing/sharing-private-apps). Here is our support documentation on this subject : > **["You cannot authorize the app" error](https://devsupport.zoom.us/hc/en-us/articles/360059617312--You-cannot-authorize-the-app-error)** > > There are a few scenarios that can cause the "You cannot authorize the app error."

Hi @donte.zoom , I can get the ZAK token for licensed user, however I cannot get the ZAK token of non -licensed user. Will publishing our app in your marketplace solve the issue? Will this help me get the ZAK token for non-licensed user? Can you also share to me what will happen once we publish my app in your marketplace? ---
