The Master Password is the password that you're prompted to create when you initially sign up to your NordPass account. To access your secure vault, you need to log in to your Nord Account and unlock your vault with your Master Password. No data stored in your NordPass account can be accessed without your Master Password.
Your Master Password is:
Never transmitted over the Internet;
Never shared with us;
Only known by you.
Thus, it’s extremely important to memorize it!
