How can I turn off a session ID?

Administration

Needed permissions: owner

Sometimes you may want to turn off a session ID and not use it to recognize visitor’s sessions. It could be because you want to stay compliant with some privacy laws or for other reasons.

A session ID is a way to identify each session based on the visitor’s IP address, operating system, browser name, browser version, browser language and enabled browser plugins. It helps to recognize events belonging to the same session. Each session ID is valid only for 30 minutes. If you turn it off, your data will be less accurate. We’ll explain that at the end of this article.

To turn off a session ID, follow these steps:

  1. Go to Menu > Administration.
  2. Navigate to Sites & apps.
  3. On the left, pick a site or app you want to work with.
  4. Navigate to Privacy.
  5. Ask visitors for consent needs to be turned off.
    Ask visitors for consent (off)
  6. Turn off Use a session ID.
    Use a session ID (off)
  7. Click Save.

  1. Some triggers in Tag Manager set cookies to work correctly.
  2. We create a session ID to recognize the visitor’s session. We use it only for 30 minutes.
  3. You can mask IP addresses for visitors under Administration > Sites & apps > Privacy > Mask IP addresses. The IP address informs about visitor’s location. Masking it can enhance visitors privacy because you won’t recognize their full location.
  4. Each event is a new session.
  5. You need to add an opt-out form (“do not sell my personal data”).
