# Enable UserCookie version 3.1

# Enable UserCookie version 3.1 {#ariaid-title1}

Release version: Australia  
Updated March 13, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Manage the version of UserCookie that is enabled on your instance to secure the storage of the secret key in the source code.
UserCookie v3 is generated only when property glide.ui.secure.cookies.use_kmf is disabled is disabled. UserCookie v3 is not secure due to storing secret key for HMAC in source code and identical for all
customers. By setting the property glide.ui.secure.cookies.use_kmf to true, UserCookie v3.1 is used and secret key is stored in security storage such as KMF.

| Category | [Session management](https://www.servicenow.com/docs/jJnJ0Q0eYjnQREHSQvPPjA "This category looks at the security of the application state for a user. Sessions should be unique to each individual, unable to be guessed or shared, and invalidated after periods of inactivity or when not required. This includes factors such as cookie attributes for cookie-based sessions, session token generation, and storage and requirements for federated re-authentication.") |
