Configuring 2 Factor Authentication One Time Password (2FA OTP) as authentication method in Nodegrid

Overview

Two-factor authentication (2FA) using one-time passwords (OTPs) enhances account security by requiring users to provide two forms of identification before accessing their accounts. OTPs are randomly generated codes that are typically valid for only a short period. They add an extra layer of security beyond passwords by ensuring that even if a password is compromised, unauthorized access is still prevented without the correct OTP. Configuration involves linking a user's account to an authenticator app, offering flexibility and robust protection against unauthorized access attempts
