Usage Notes

TOTP codes are time-based and valid for a short window (typically 30 seconds); ensure server clock synchronization to avoid false negatives. Place a Web Page node before this one to collect the 6-digit code from the user. The false output should route to a retry path to allow the user to re-enter the code before locking them out.
