Alternate identifier used to reduce linkability while preserving account functionality.

Definition

In plain English Alternate identifier used to reduce linkability while preserving account functionality.

Why this matters

Why it matters: Reduced linkability lowers profiling risk and limits exposure if one alias is leaked.

Example

Example: Use a unique alias per service (and separate recovery email) to prevent cross-service correlation.
