You can decide whether you want your participants to ask questions and answer polls anonymously or with their names, by default. 


Even if you’re using Single Sign On (SSO), your audience can interact with Slido totally anonymously. If you'd rather everyone use their names, you can set this up too. This can be done through privacy settings on both an event and organizational level.

Available in Professional, Enterprise, Premium, and Institution plans. 

In this article: 



Participant privacy options


You can choose from four options: 

  • Anonymous by default
  • Named by default
  • Always stay anonymous
  • Always require name

These options don’t affect the Quiz (where participant names are required) nor the Ideas feature. 

Please note that you Slido can’t store data of external participants in Webex meetings and webinars. Names of participants outside of your Webex organization will show as ‘anonymous’ in exports. 


Here’s how participants will see particular options when typing in a question: 

Anonymous by default - Questions and poll votes are submitted anonymously unless participants switch to their names

Submitting a question or a poll vote: Anonymous by default

Named by default - Questions and poll votes are submitted with participant names unless they switch to anonymous. 

Submitting a question or a poll vote: Named by default

To ask for a name when participants join the event, turn on also the require name option. You can find it under Privacy Settings > Require authentication


Always stay anonymous - Questions and poll votes are submitted anonymously with no option to switch to their names

Submitting a question or a poll vote: Always stay anonymous


Always require a name - Questions and poll votes are submitted with participant names with no option to switch to anonymous.

Participants will be asked to enter their name when joining the event as shown in the example below: 

Request for names when joining an event
Joining Slido with required name
Submitting a question or a poll vote: Always require name


Please note that participants can use any names, including “Anonymous”. It is also possible to change their name in the Profile. Once changed, the new name will apply to any previously submitted questions and poll votes.


You can select your preferred option for your event, or lock it for all future events in Organization settings. 


Changing privacy settings for a single event

To select your preferred option for your current event: 

  1. In your event, go to Settings
  2. Select Privacy on the left
  3. Click the dropdown in Participant privacy and choose your option
Changing the Participant privacy settings on event level



Changing privacy settings for all new events

If you want all your future events to be set the same way: 

  1. Click your initials in the top-right corner
  2. Select Organization settings and billing
  3. Click the Privacy option on the left
  4. Navigate to Participant section and choose your option from the dropdown
Changing the Participant privacy settings on organization level

Once you hit save, all newly created events will be set to your selected option by default.


If you want to have a different setting for a single event, you can adjust it in Event Settings > Privacy

To prevent changes for individual events, click the lock icon next to the dropdown:

Locking Privacy Settings for individual events

This is what the locked option looks like in Event Settings - drop-down option will be greyed out and a pop up window saying “Feature locked” will appear after clicking on it:

What I would really like to see is the below. 

If I have enabled the requirement for al participants to log in using company domain name, 

How come admin cannot access the email address they used?

I say this because I dont do anonymity and all the participants know this so , If I receive very specific feedback, I want to reach out to the individual and resolve the issue. 

I have read through the responses here and I dont think this is possible yet its appears quite basic

Hey @Rouven Webcast Account,

At the moment, Webex can’t capture data of participants who aren’t in your Webex organisation. Even if you have all the settings you mentioned, external participants will still show up as anonymous in your exports.

To capture external participants’ data, you can either ask them to join Slido via a browser by using the event code or the QR code. Alternatively, you could run a survey which asks participants for names and email addresses. When you export Poll results per user, their answers across polls will be connected.

Hope this helps :)

Hi Beatrice,

I don’t work for Slido, but I might have answer. It looks like the “Anonymous” next to the “Red A” is the name of the user answering questions in your screenshot. You can try to change the name “Anonymous” by tapping/clicking on it. 

I also like to test my Slido events using an incognito/private browser, and on my phone. This way, I can see what the users will see.


To open an Incognito/InPrivate browsing session from Chrome or MS Edge,  Press Ctrl+Shift+N

This new window won’t have you logged in to any sites or applications.


Hope that helps!


I just used Slido integrated in Webex Webinar within a customer Webcast.

As we want to use the polls for the lead generation it is mandatory to get the participants name and email-address. As requested that is possible in the meanwhile within slido.

My Slido privacy settings:

  • Participant privacy - Always require name
  • Require authentication - on
  • Require name - on
  • Require email address - on

It mainly seems to work for logged in users of my company and guests using the Webex desktop client.

Unfortunately its seems that some guests within the Webex browser client are still  anonymous.

Screenshots of two different polls in two different Webex Webinars:

I could replicate this behaviour in the second case by using my private Webex account with the browser client (unfortunately in german language):

Slido does not take over my login credentials but old ones I have used previously als user “I am the Browser”. As long I do not click on “continue as I am the Browser” (Fortfahren als I am the Browser) within my profile, I am anonymous in the Slido event.


I’m not sure what’s going wrong here but this forces me to use the Webex internal polls again.

Can you please assist with this? 


I would like to have my participants be named by default. I followed the instructions above to change the Participant Privacy settings accordingly but the options still show “Stay as Anonymous” and “Switch to Anonymous”.

May I know how I can fix this?


I am on the Webex plan (SSO).


Thank you for your help.
