How UID2 is different

Interoperable

UID2 works with other identity solutions across the open internet to maximize coverage of addressable audiences across all channels — including on Connected TV.

Portable

Since UID2 has been adopted by many leading ad tech providers and platforms, it’s easy for participants to use the identity strategies that work best for them, with the partners they choose.

Privacy-conscious

Omnichannel

Authentication is increasing across traditional digital, mobile apps, and especially Connected TV — enabling cross-device and cross-channel identity strategies without cookies.
