Authentication 101

What is SMS OTP?

SMS OTP, or SMS one-time password, is a short-lived authentication code sent to a user's mobile phone by text message.

What is Risk-Based Authentication?

Risk-Based Authentication (RBA) uses contextual, behavioral, device, and transaction signals to allow access or require extra verification when risk rises.

What are Passkeys?

Passkeys are FIDO credentials that use public-key cryptography to provide phishing-resistant, passwordless sign-in to websites and apps.
