- Log in to Adobe Experience Platform Data Collection using your AdobeID credentials.
- Click the desired tag property.
- Go to the Extensions tab, then click the Configure button under Adobe Analytics.
- Expand the Cookies accordion, which reveals the Cookie Lifetime drop-down list.
This drop-down list contains the following values:
- Default: Cookie expires after 2 years.
- None: AppMeasurement does not set cookies.
- Session: Cookie expires at the end of the visitor’s session.
- Seconds: Cookie expires after the specified number of seconds have elapsed. For example, setting this drop-down list to Seconds and placing
86400into the custom field forces cookies to expire after exactly 24 hours.
