Slido is an easy to use audience engagement tool. It helps people to get the most out of meetings by bridging the gap between speakers and their audiences.

When Slido is integrated into your Control Hub organization, your users can add the Slido app to their meetings in Webex. This integration brings additional Q&A and polling functionality to the meeting.

As an administrator for your Webex organization, you can enable Slido in Control Hub.

  • This action automatically creates a Slido organization for you, and you become the owner.

  • The integration applies to all your meetings sites and can immediately be used by all your meeting hosts.

Sign in to Slido with your Webex account to customize the Slido experience for your users.

For Webex administrators using Slido for the first time

You can enable Slido from Control Hub. When you do, Webex creates a new Slido organization for you. Your Webex account becomes the owner.

The Slido app is then available to users in all of your organization's Webex sites. When users click on the Slido app from the Webex app, they become a new user in your Slido organization.

We call this "on-demand" or "just-in-time" (JIT) provisioning.​

When Webex creates the user in Slido, it supplies the user's token to authenticate them.​

We recommend that you sign in at to manage roles and configure your Slido organization. You must use your Webex account to sign in to Slido.

For users

When a Webex meeting host uses Slido for the first time, they automatically get a new Slido user account. The account is created in your Webex-linked Slido organization.

The host manages Slido interactions from the Webex app.

To prepare Slido events / interactions in advance, or to access Slido data after the meeting, hosts can sign in to Slido at Users must sign in with their Webex credentials.

For Webex administrators who already use Slido

You already have a Slido organization, but the integration works exactly as described above for Webex orgs using it for the first time.

When you enable Slido from Control Hub, Webex creates another Slido organization for you. Your Webex account becomes the owner.

The Slido app is then available to users in all of your organization's Webex sites. When users click on the Slido app from the Webex app, they become a new user in your new Slido organization.

Unlike Webex organizations in Control Hub, Slido users can belong to multiple Slido organizations.

You can manually merge your existing Slido users, and their Slido content, into your new Slido organization. You must contact Slido support to get help with this option.


  • At the time when a Webex app user first uses the Slido app, they become a user in your Slido organization. So your Slido organization has a subset of the users from your Webex organization.

  • Those users can sign in to your Slido organization directly. If they do, they must use their Webex accounts ("Log in with Webex") and have already loaded Slido from the App panel in the Webex app.

  • After you delete users from your Webex organization, they cannot directly sign in to your Slido organization.

  • If you need to change a user's email address, follow the normal procedure for changing it in your Webex organization, and then change it manually in your Slido organization.

Identity, security, and compliance

  • Your Slido organization enforces Log in with Webex as the only way users can sign in. Webex acts as an identity provider for Slido. So your Webex access controls (like SSO) govern users who access Slido directly.

  • Slido admins have access to view any content created by all users in the Slido organization.

  • Your Slido organization, users, and their content are not governed by the same set of standards as your Webex organization, users, and content.

  • Read about Webex Security and Privacy.

Change of Slido license ownership

As the Slido license owner, you can transfer ownership to another person at any time. Read

Webex Host licenses

All hosts in your Webex organization are entitled to associated Slido accounts. You can manage Webex meeting host licenses / entitlements in Control Hub.

For example, you can assign host licenses to users with a license assignment template. That entitles the Webex users to use Slido.

All licensed hosts across all your meetings sites are entitled to use Slido. There is no site by site control. Apart from the host license, there is no user by user control.

License Centralization

This section only applies if your organization used Slido before using it with Webex.

We strongly recommend that you centralize your Slido users and their content, because doing so gives you:

  • A simpler Slido experience for meeting hosts.

    (This is the only way users will be able to use the integrated Slido and Webex apps.)

  • Control over all your organization's Slido data in one place.

  • Ability to enforce company-wide Slido settings.

You should merge all user content under the (Webex) Slido organization, and claim ownership of your associated user domain(s).

Important: Your domain claims in Webex do not automatically transfer to Slido. Similarly, your domain claims in Slido do not automatically transfer to Webex. You should claim them in both places if you want to restrict sign-up by domain.


Important: Your Webex data retention policies (set in Control Hub) do not automatically apply to your Slido organization.

Read about data retention policy in Control Hub at

Contact to request a specific data retention period for your Slido content, if you want to align it with your Webex retention period.

The daily data retention job checks the DATE TO property of all your Slido events, and adds the retention period to determine whether to delete the event data. The job runs against all events in your account, including events from the past.

For example, if DATE TO is 35 days from today, and your retention period is 5 days, the event data is deleted 40 days from today.


All Slido content created through Webex is stored in a Slido organization that enforces Webex as the only login type.

All Slido data is stored in a European data center.

Security-related documentation

  • Slido integration is not available with Webex for Government.

  • Slido functionality is not available in end-to-end encrypted meetings.

  • English is currently the only language available in Slido for Webex meeting hosts.

    Other participants see the Slido app in the language they use for Webex Meetings.

  • Webex users must be created in or linked to a Control Hub organization.

    Slido is not available to meeting hosts in Site Admin managed sites, unless the site and users are linked to Control Hub.

  • Slido features are not available to web client users who are not subscribed to Webex.

  • Hosts must be logged in to their Webex meetings site to host Slido interactions. If they have more than one meeting site, they must be logged in to the site that is hosting the meeting.

  • We have a limit of 5000 participants using Slido. If you want to use Slido at a bigger event, contact

  • The Team page of can suffer from performance issues if the Slido organization has more than 1000 users.

See Known Issues and Limitations for Polls and Q&A in Slido for information on those specific features.

Network preparation

Configure your firewall to allow HTTP/S connections to the following domains:



  • *


  • *

Event hosts

The person hosting the Webex meeting needs the following:

  • Cisco Webex Meetings version 41.6 (or later) on a supported platform.

    Currently hosts must use Webex Meetings on Windows or MacOS.

    Read the system requirements.

  • Microsoft Edge WebView2 installed (if the host is using Windows).

    We recommend you push this component to your Windows users before you enable Slido.

    Otherwise, Slido prompts users to install it on first use. Download and install can take several minutes which could impact your meeting experience.

  • Push the component that matches your Windows environment—either 32-bit or 64-bit.

Supported platforms for attendees to participate in polls:


Sign in to Control Hub at, and go to Management > Apps.


Scroll to Slido, and then toggle on the setting to enable the integration.

If you don't see the name Slido in the list of apps, you can use the ID to find the Slido app. Select to search for the app by ID and paste the following text into the search field (without the line break):

Then you can select and enable the Slido app from the search result.

The step creates a Slido organization and makes you the owner.


Click Login to open and sign in to the Slido admin portal.

What to do next

Configure your Slido organization.

These are changes we recommend that you make in the Slido administration portal.

Before you begin

Enable Slido in Control Hub to create and sign in to your Slido organization.


Create new administrators if you need them. Open the Team tab and click Invite.

Managing Slido is easier if you have other administrators, but as the owner and full administrator, only you can do this first step.

When you grant other people the Slido administrator role, they can do all the team management tasks.

(Remember that Webex creates new users automatically in your Slido organization.)

If you have Azure AD, you can use an enterprise setting to enable provisioning from the Azure AD user base.

You can learn more about Slido team management features and organization roles in this article: All About Team Management.


Click on your profile (top right, your initials) and select Organization settings and billing.

These settings apply to all events created under your organization.

We recommend the following:

  • Update the name of your organizationFollow these steps.
  • Set default privacy settings—By default, all Slido events created under your organization are protected by a randomly generated 6-character long password. Alternative options include:

    • Google SSO

    • SAML SSO

    • Email verification

    • Public events

    There's a way to configure Event privacy for all events. Read for more information.

    If your Slido events include people outside of your organization, do not enforce SSO by default.
  • Change the language of your Slido events—If the default English is not your preferred event language, you can change it in Organization settings > Present mode > Language. Slido offers more than 30 languages that can be used as the default for all your new Slido events.


    This setting only affects participant experience. Slido Admin language change is not supported.

  • Upload your company logo—Personalize Slido by going to the Organization settings > Present mode > Account logo to upload your company logo. While you're there, you can change the Theme to match your branding.

    You can make further customizations at the Slido event level: Add branding and custom colors to your events.


(Optional) Claim your domain to make sure people in your company don't create their own personal Slido accounts.

A claimed domain restricts user signup and makes sure the accounts are part of your team organization. You can claim multiple domains in a single Slido organization.

Important: Your domain claims in Webex do not automatically transfer to Slido. Similarly, your domain claims in Slido do not automatically transfer to Webex. You should claim them in both places if you want to restrict sign-up by domain.


(Optional) If you need your Slido data to be deleted at a regular cadence, this form to raise a request.

Be aware that if you have a data retention policy for your Webex account, Slido isn’t covered under this policy.

This task only applies if your people were using Slido before you enabled it for your Webex organization.


Please submit the details for your account in this form.


The Slido team verifies your claim to the requested domain, and provides you the list of Slido users in that domain.


Mark up the list with your decision for each user:

  • For users in your organization: migrate users and their content to the Webex-associated Slido organization.

  • For users who left your organization: delete users and their content from Slido.

  • Not recommended: Leave users and their content in the original Slido organization/s.


Return the list to Slido support.

To make sure that people in your company don’t create their own personal Slido accounts but are instead part of your team's organization, you can restrict their Slido sign-up.

If you want to request restricted signup for multiple company domains, please claim those domains in Control Hub. To verify that you claim those domains, you can share a screenshot of the claimed domains from Control Hub when the Slido support team contacts you to provide assistance.

User access

No Webex users can see Slido app:
  • Check that Slido is enabled in your organization.

  • Check your firewall is allowing access to Slido specific domains.

Microsoft PowerPoint and Google Slides integrations don't work

The meeting host (Slido admin) needs to enable Q&A for the Slido event, otherwise these presentation integrations do not work.

Some hosts can't find the Apps tab, or can't find Slido in the apps tab (appHub) :
  • Check that the users exist in your Webex organization.

  • Check that the host is logged in to the meeting site.

  • If your meeting site is linked from Site Admin, check that the affected users are also linked.

  • If a user was promoted to cohost during the meeting, they don't see the Apps button.

  • Mobile client and Web client don't support the Apps button.

  • The Webex Events (New) large events do not support the Apps button.

Slido app does not work as expected for some users:
There could be a security restriction preventing the user's access to Slido. Read
Meeting host can't create or link to a Slido event
  • Check that the host is logged in to the site that's hosting the meeting.

User sees "Wait one moment" for a long time when the poll starts
If the user is on Windows, check that WebView2 is installed.

For any changes to user access to Slido, you must make the changes in the Slido admin portal at As long as a meeting host is authorized to access Webex under your organization, they are allowed to gain access directly to Slido.


To disable Slido for your organization, sign in to, then Management > Apps, and turn off the Slido setting.


Delete all Slido content from your Slido organization by following Deleting your Slido account.


This is an irreversible action that can only be done by the Slido account owner.

Will Slido be free with Webex? Is there additional pricing for customers to use Slido?

A full Slido license is included (with no additional pricing) in all Enterprise Webex plans.

Slido licenses are not included in plans that you buy directly from

Will the standalone version of Slido be available at no cost to Webex clients?

Yes, all paid Webex clients will have access to the full version of Slido (whether they use it as an integration within the Webex meeting, or standalone).

What if I already have a Slido account and I want to access the Slido linked to my Webex organization?

  • If you signed up for Slido before you started using it in Webex, you could have access to multiple Slido organizations. You could also be using the same email address with multiple Slido organizations. The organizations could have different sign in methods.

    We require that you select Login with Webex when you get to the Slido sign in page. Slido redirects you through your normal Webex sign in flow to authenticate you for access to Slido.

    If your email address is linked to multiple Slido organizations, and you signed into a different one, then you can switch organization to get to your Webex-linked Slido organization. Read

    Switching requires you to sign in again, and you must choose Login with Webex.

How long is the administrator session timeout, and can I change it?

The default session timeout is 60 days. You can change it by signing into and going to Organization Settings > Privacy.

What roles are available in Slido, and what can they do?

In order of increasing privilege, the Slido roles are: Guest, User, Admin, and Owner.

A Slido Guest is allowed to manage Q&A and polls for a Slido event, but has no access to event or organization settings. You can invite guests directly to a Slido event.

Slido grants the following privileges to the other roles:

Privilege User Admin Owner

Create new event




Access member events



Invite others to the license



Update roles



Access account settings



Assign new owner


Manage event features




Access SSO settings


What happens to a user's events when they leave the company?

What happens to a user's analytics when they leave the company?

Analytics are linked to the events. The analytics data moves with the events, when the events are transferred as described in the previous answer.

Can I use Slido to invite a guest to help me manage the Slido interactions in a Webex meeting?

Yes. You can invite the guest from the Slido interface by sending an email or copying out a shareable link. Read

You can't invite a guest from outside of your organization.

What happens to Webex cohosts in Slido?

If you nominate a cohost during the meeting, Slido does not automatically add them to the associated Slido event.

We recommend that you invite your cohost as a guest to the Slido event so they can help you manage the event from You can't invite a guest from outside of your organization.

Read about Cohosts for Webex Meetings.

How is SCIM (System for Cross-domain Identity Management) provisioning to Slido affected by the integration with Webex?

When the two systems are integrated, Webex creates Slido users as needed. This is called just-in-time (JIT) provisioning. You cannot also use SCIM to create Slido users in the same Slido organization.

What happens to the existing Webex Q&A and polling features?

We intend to eventually replace the existing Webex features as we improve the integration between Webex and Slido.

Can you prevent users from artificially weighting feedback by submitting multiple responses? ie. feedback/voting

Yes. The basic security options allow each participant to vote only once on their device from the same browser. Without further authentication enabled for the event, participants can potentially vote multiple times from different browsers, devices, or incognito windows. You can solve this by requiring SSO for the event.
