Account Recovery.
The flow that re-establishes a user's access to their account when they've lost their credential — and the most-attacked surface in any CIAM deployment.
The audit data consistently shows recovery flows as the point where most account takeovers actually happen. The login surface is hardened with MFA and rate limiting; the recovery surface is often a single channel with looser rate limits and weaker verification. Designing recovery deliberately — multiple signals, delays for high-risk operations, separate factor classes from login — is the single highest-leverage CIAM security investment after MFA itself.
