The master password is your personal password for accessing your lockers. You will create your master password when setting up your NordLocker account. We never store your master password neither in the application nor on our servers.
Make sure you memorize or save your master password in a safe place. You won’t be able to access the encrypted files without your master password. Don’t share it with anyone.
During your registration, you will be given a master password recovery key. Make sure to copy it and store it safely.
