Slido is gradually rolling out a new user interface. If the below steps and visuals match what you are seeing within your account, then you are using the new interface and this article is for you. If not, please see this version

When needed, you can secure your slido by adjusting its privacy settings. Although the options will vary depending on your plan, even Basic slidos can be hidden from search and protected by a passcode.

The availability of these settings varies by plan. Please check the respective part of the article to see which setting is available with what license. Our free Basic plan does not offer any of the mentioned options.

Access your Privacy settings

To change the Privacy settings of your slido, follow these simple steps:

  1. Open up your Settings
  2. Select the Privacy tab on the left side
  3. Toggle on Require authentication to see all options (require name, email, passcode, single sign-on, etc.)

It’s under Require authentication where you can set your slido to require name, email, passcode, or even Google or SAML single sign-on (SSO).



Notice that this is also where you can designate your Participant privacy settings. This determines if participants will respond with their names or anonymously. See our guide to learn more. 

​​​​​​​Hide your slido from search


Available in all plans.


Enabling this option hides your slido from search suggestions. Only those who enter the exact slido code will be able to access your slido during its dates.

Pro tip: Use a very specific code – something that’s easily recognizable for your attendees, but difficult for anyone to mistake as a different slido.


Secure your slido with a passcode


Available in all plans.


When enabled, only the participants who enter the correct passcode will be able to join your slido. Use a passcode that's easy to remember, but includes both letters and numbers to make it harder to guess. 

Along with a passcode, you can also require a name or email address. Keep in mind, however, that participants can enter any name or email address. 


Restrict access to your slido


Available in our Professional plan and higher.


This option allows only participants with a certain email to join your slido. You can either add a list of email addresses (max 1,500) or restrict access to specific email domains.


When joining, the participants will be required to enter their email. If their address or domain matches your list, they’ll receive a 4-digit access code in their inbox. If their email does not match, the system won't let them in. 

Please note that if a participant joins for a second time on an alternate or incognito browser, they’ll need to re-verify their email address with another access code.


You can also require an email address without restricting the access. This will help you collect email addresses from participants, but won’t protect your slido from unauthorized access.


Set up SSO for participants


Available in our Enterprise, Premium and Institution plans.

To protect your data, you can configure your privacy settings to require single-sign-on (SSO) authentication. With this enabled, only the people from your SSO list will be able to join your slido. Please see our comprehensive SSO guide for setting this up.


Pro tip: Test out your privacy settings. You can test the participant experience of joining your slido by clicking the view as participant option in the bottom right corner. Or you can always copy and paste the joining link into an incognito or alternate browser

It would be great if this KB article could be updated to include step by step instructions for the different authentication options. Right now, for SAML SSO, it redirects the user to the SSO article which is really for administrators. 

Something else to consider is to identify administrator and user steps. This could keep your KB articles to one, and differentiate the steps.

The video above shows what we are looking for, but, it doesn’t match the rest of the document.

We are trying to reduce the amount of custom documentation that we provide since that is always out of date it seems as service providers update their services and products continuously (which is good!) so we rely on clear instructions from the vendor.

Hi @Lelio Fulgenzi,

Thank you for your feedback! 

Creating SSO guides for participants is a little complicated as every Identity Provider has their own flow, but I can see that it would be helpful.

Sorry about the outdated video, we are currently working on updating all gifs and we’re trying to replace them ASAP.

Let us know if you have any further feedback :)

Hi @Meggie from Slido 

Sorry if I wasn’t clear. I’m not expecting detailed instructions for each individual Identity Provider. Just a clear set of instructions for each type of SSO you support.

For example:


click on privacy

click on SAML SSO

click Upload XML

click Save

NOTE: Contact your local Slido admin for information on how to get your SAML XML file.


That’s it. And please don’t remove the video! The video is actually excellent since it has the steps you need. I like the circling of the cursor. We just need it “in print” on this page.

Hey @Lelio Fulgenzi,

I see! Thank you for explaining 🙂 We do have a detailed, step-by-step guide for setting all types of SSO we support, but it’s good to know that it might not be detailed enough. I will pass this on.

Also, just to be clear, only admins and account owners can set up SSO at the moment.

Let us know if we can help with anything else!

Once SSO is setup by the account owner and the relationship between Slido and the IdP is setup, then any host can enable Participant SAML SSO by uploading the XML file.

It is this host level instruction set we need. 

We are trying to avoid custom solutions and instructions where ever possible since the sites changes so often. So really, it’s up to the vendor to provide these instructions. Without them, the clients get frustrated. 

You can reach me direct if you want to have a more indepth conversation.
