Adaptive Authentication
Authentication
Authentication that adjusts required steps based on computed risk from contextual signals and behavior.
Definition
Adaptive authentication evaluates signals (device history, location, IP reputation, behavior) to decide whether to step up, block, or allow. Privacy-friendly designs minimize invasive signals and retention.
In plain English
Authentication that adjusts required steps based on computed risk from contextual signals and behavior.
Why this matters
Why it matters: Reduces account takeover while minimizing friction, but can create opaque tracking if overused.
Example
Example: Use short-lived, privacy-preserving signals and provide transparent user recovery paths.
