You only need an ID if you want to partake in adult beverages. I got carded in Disneyland last year at the gate while park hopping, but that was because of some new picture system they were trying out. I have never been carded at WDW or Universal other than at hotel check in.

For most guests in 2026, a physical government ID is not required for daily entry into Walt Disney World or Disneyland theme parks; your valid ticket and potentially a biometric finger scan (at WDW) are the primary entry methods. However, valid identification is essential for several specific scenarios: if you are using a Florida Resident or California Resident ticket, you must show proof of residency at the ticket window. Additionally, an ID is required to pick up tickets at "Will Call," to verify your identity if your ticket media is lost or malfunctioning, and for any guest over 21 wishing to purchase alcoholic beverages. While children under 18 generally do not need an ID, it is a peer-to-peer best practice for adults to carry a driver's license or passport anyway, as Disney reserves the right to request "valid identification confirmation" for entry, re-entry, or park-hopping on any day of your ticket's validity.
