QR Authentication for mobile apps | Zimbra

Alert! This article is written for Zimbra OSE users. As of December 2023, Synacor will no longer be providing support for Zimbra OSE. You might want to consider trying out Carbonio Community Edition – Zextras’s free and open-source email and collaboration platform.

For additional guidance, check out our community articles detailing the process of migrating from your current platform to Carbonio CE.

QR Code authentication for mobile apps ( such as Team App and Drive App ) is part of Zextras Auth and can speed up and manage login to those application.

 The first thing you have to do is to create a QR Code in the Zimbra WebClient and then it will be scanned by the user from the app’s login page to be able to log in.

QR Codes are a one-time credential only, meaning that once generated it will grant access to the app until the relevant credential itself is deleted from the account. Once generated, the QR Code can only be viewed once.


The QR Code Application Password feature needs some properties to be set at domain level to function properly:

  • zimbraPublicServiceHostname
  • zimbraPublicServicePort
  • zimbraPublicServiceProtocol

Should one or more of the properties be unset, a notification will be delivered to the Admin reporting the affected domains and their missing properties.

Creating a new QR Code Credential

First of all you have to open the Zextras Auth Zimlet and then click on “new password” and enter one of your choice in the proper field. Then select “QR code” as the Password Type:

Click “next” button to continue. You will see the new QR Code displayed on your screen:

QR Codes are randomly generated and cannot be displayed again after the creation is complete.

After clicking on “Done” button, you will see an entry for the new Mobile Password in the “Active Passwords” list of the Zextras Auth Zimlet.
