Two-step authentication helps to protect you by making it more difficult for someone else to sign in to the ESA DMPL Tool (web version) with your DMPL Tool account.- Use the built-in QR code scanner to link the ESA DMPL Tool Authenticator app to your DMPL Tool account- After entering your password to login to the DMPL Tool (web version) you’ll be asked to enter the Time-based One-Time Password (OTP) generated by the app to verify your identity- Each OTP code is randomly generated. The countdown timer shows you how long the code is valid.- The app doesn’t require you to be connected to a network and won’t drain your battery. Note: you must have a ESA DMPL Tool account to use this app and have OTP Authentication enabled. Please contact the DMPL Tool Administrator should you require further instructions.
