## Improvement updates

- [Account Security Upgrades: Passkeys, Smarter Client Trust, zxcvbn, Turnstile](<https://novu.co/changelog/improving-security-in-novu/>): 2026-05-07T15:05:00.000Z - Sign in with a passkey, skip Client Trust when 2FA is on, get real password-strength scoring at signup, and run into bot challenges only when traffic looks suspicious.
- [Throttle Step](<https://novu.co/changelog/throttle-step/>): 2025-10-09T15:52:00.000Z - The new Throttle Step allows you to limit the frequency of a workflow execution for each subscriber within a specified time window. This will prevent duplicate or excessive notifications across all channels. You can use fixed or dynamic windows. Perfect for managing high-frequency alerts, cron jobs, or multi-project notifications.
