Factors like network connectivity or other applications on your devices can impact the performance of Webex App even when you meet these requirements.


We don't support using Webex App with prerelease or early release programs, such as the Apple Beta Software, Windows Insider Program, or similar programs.

Windows recommended minimum system requirements


We continuously review and revise these requirements.

Mac recommended minimum system requirements


We continuously review and revise these requirements.

  • MacOS 10.13 and later.

  • M1 chip or Intel CPU-based (4 GB of RAM minimum recommended).


Your organization may require you to run the Webex App in FIPS mode. To do so, set the following registry key to 1 (DWORD value) on user computers:

HKLM\SYSTEM\CurrentControlSet\Control\Lsa\FipsAlgorithmPolicy\Enabled

To change this setting, you must have HKLM registry access. Typically, an administrator or user with admin privileges has this access.

Since this is an OS-level setting, we recommend that you evaluate its impact on your other Windows applications before rolling it out across your organization.

If you don’t enable the registry key, note the following:

  • You don't lose any Webex App functionality.

  • We still support your organization.

  • Webex App still uses FIPS-compatible algorithms and TLS 1.2. However, the operating system libraries (such as WinHTTP) don't run in FIPS mode.

To enable Webex App to connect to the Webex for Government cloud for your users, choose the appropriate option for your needs:

Do these steps if you prefer deploying the Webex App as an administrator-controlled MSI install.


To perform this action, you must have HLKM registry access. Typically, an administrator or user with admin privileges has this access. The FEDRAMPENABLED setting causes the installer to write to the HLKM area of the registry.

Before you begin

Enable the FIPS registry key, if necessary.

1

Download the installer using the applicable link.

2

To enable usage of the Webex for Government cloud environment, run msiexec with the FEDRAMPENABLED=1 option along with any other options that you need.

Example:
msiexec /i WebexTeams.msi FEDRAMPENABLED=1 ALLUSERS=1

Do this task if you want users to download and install the Webex App MSI themselves, while ensuring that they connect to the Webex for Government cloud.


To perform this action, you must have HLKM registry access. Typically, an administrator or user with admin privileges has this access.

Before you begin

Enable the FIPS registry key, if necessary.

1

Set the following registry key to 1 (DWORD value):

HKLM\Software\Cisco Spark Native\FedRampEnabled

2

After you set the registry key, ensure that all users sign out and sign back in.

We recommend this approach to configure FIPS and FedRAMP modes for MacOS. Deploy an MDM configuration profile that contains these settings. The exact details for configuring this depend on your MDM solution.

1

Download the DMG installer from the following link.

2

Set the following two Boolean keys to true in the preference domain Cisco-Systems.Spark:

FipsEnabled

FedRampEnabled

Example:

If you don't have an MDM solution, you can change the default values for FIPS and FedRAMP using the defaults command. The end user can potentially override values set through defaults, so we recommend using MDM when possible.

Enter the following commands:

defaults write Cisco-Systems.Spark FedRampEnabled -bool true

defaults write Cisco-Systems.Spark FipsEnabled -bool true

1

Start the Webex App.

2

Click the down arrow beside Webex and select Webex for Government from the list.

Webex App restarts to take you to the FedRAMP sign-in page. That page directs the authentication to the Webex for Government identity service and enables FIPS 140-2 mode.

3

Enter your email address and check I agree to terms and conditions, then click Next to sign in.

The first time you sign in, you must set up a password.

Your administrator doesn't perform any special tasks to set up or connect to the Webex for Government cloud from the mobile Webex App. Your users must sign in for the first time using the following method. To use MDM/MAM or app wrapping options on user mobile devices, see the Webex | Secure Mobile Devices help article.

1

Download Webex App:

2

Start Webex App, tap Get Started.

3

Tap the down arrow beside Webex to open the App Configuration panel.

4

Select Webex for Government from the list.

Webex App restarts to take you to the FedRAMP sign-in page. That page directs the authentication to the Webex for Government identity service and enables FIPS 140-2 mode.

5

Enter your email address and check I agree to terms and conditions, then click Next to sign in.

The first time you sign in, you must set up a password.

To uninstall the app use msiexec /x Webex.msi.

To uninstall Webex App, go to the Applications folder and drag Webex App to the trash.
