Device binding is often treated as a strong security control.
In reality, it behaves more like a weak signal than a reliable boundary.
Most systems assume that if a request carries the same device token, it must be the same device. But tokens can be replayed, environments can be cloned, and client-side checks can be manipulated.
⚙️ The real shift is architectural — trust should not sit on the client. Device identifiers and runtime signals are indicators, not guarantees.
A stronger approach combines server-side validation, attestation signals, and behavioral context — while accepting that none of these are absolute.
