# Integration of User Login via Notification

With OneSpan Cloud Authentication, you can implement a two-step authentication process, where users need to perform an additional authentication step. In this additional step, the user must either respond to a Push Notification message (see [Integration of Push Notification-based authentication](/sec/docs/oca-ig-integration-of-push-notification-based-authentication)) or enter a one-time password (OTP) received in a challenge SMS or email (see [Integration of User Login via Notification—SMS or Email](/sec/docs/oca-ig-integration-of-user-login-via-sms-or-email)).
