When needed, you can secure your event by adjusting its privacy settings. Basic events are visible in the search results and can be accessed by typing in the event code.


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.

To prevent anyone accessing your event you can choose from the following options in Privacy settings:

  • Hide your event from search
  • Secure your event with a passcode
  • Restrict access to your event
  • Set up SSO for participants

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

  1. Go to Settings
  2. Select Privacy on the left
  3. Click the toggle to turn on your option

Toggling on Require authentication expands additional options for a name, email and Google SSO or SAML SSO settings.




It’s possible to combine multiple privacy settings.

Hide your event from search


Available with all our paid plans.


You can hide your event code from the search suggestions. Only those participants who have the exact code will be able to access the event during the dates of the Slido event.


Quick tip: For an additional level of security, use abbreviations or a combination of numbers and letters for your event code. Visit the link to get more ideas about event code customization.


Secure your event with a passcode


Available with all our paid plans.


Only the participants who enter the correct passcode will be able to join your Slido event. Use a passcode that's easy to remember, but includes both letters and numbers to make it harder to guess. Try to avoid replacing O's with zeros as it can cause confusion.


When running a contest, exam or an internal session, you might need to see the names of participants who voted in Polls. By also ticking the option Require name in Privacy settings, you’ll see this information in Polls per user export. The participants, however, still have the option to switch to anonymous while voting.


Restrict access to your event


It is not possible to restrict access to your event with our Engage, Internal and Teacher plans but you can still ask participants to enter their email address before joining the event.


This option allows only participants with a certain email to access your event. You can either add a list of email addresses or restrict access for a particular domain.

When joining the event via event link, event code, or a QR code, the participants will be required to type in their email. If they're on the list, they will be sent a 4-digit access code to their inbox. If they're not on the list or try to enter via a different domain, the system won't let them in.

Set up SSO for participants


Available only with our Enterprise and Institution plans.


To protect your data, you can set up privacy settings through single-sign-on authentication for your employees, so only the people from the SSO list can join. Our SSO article tells you how.

  • Tip 1: Testing your Privacy settings
    To test various privacy options, you can use the Participant mode on the left side of your Admin. While adding restricted access or setting up SSO might kick you out of the event, you might need to refresh your page or use the event link in an incognito window with others.

    For example, if you tried to enter the event and added the passcode to your privacy settings afterwards, the system will remember you and won't ask for the passcode the next time. In that case, just copy your event link under the "share" button in the upper right corner of your Admin, and open the link in incognito mode or in another browser.
