Building Multi-Factor Authentication with TOTP and WebAuthn
Multi-Factor Authentication (MFA) is a method of verifying a user’s identity by requiring more than one form of evidence, such as something they know, something they have, and something they are. In this guide, we’ll dive into implementing two popular MFA methods: Time-Based One-Time Passwords (TOTP) and Web Authentication (WebAuthn). What is Time-Based One-Time Password (TOTP)?
