LightWAN Authenticator vs Subnet

LightWAN Authenticator (“Authenticator”) is a software-based authenticator by LightWAN Technology that supports multifactor authentication (MFA), by which the Authenticator offers a user-friendly and secure way to log into your online accounts.   The Authenticator generates multifactor authentication codes in your browser and application. Use it to add an extra layer of security to your LightWAN account, or any other accounts supporting One-Time Password (OTP). Once the MFA is enabled, you are suggested to enter your account password, as well as the dynamic token generated from the Authenticator, when you are logging into your account. After configuring, there’s no need for Internet connection to get the dynamic token.   Features: - Add accounts by scanning QR codes - Authenticate multiple accounts - Generate time-based dynamic token synchronously
