Your Master Password is used to unlock your NordLocker vault and to have access to the encrypted files. It acts like a key to unlock your information.
You will be asked to enter it when trying to access the information stored inside any locker.
Also, your opened lockers will be locked once your computer locks.
These security measures are here so no third parties could access your data.
Make sure to keep your Master Password safe and the Recovery Code stored somewhere you could access it.
In case of a loss, you can reset your Master Password with the Recovery Code.
