The master password
The master password is the basis for your secure passwords. All generated passwords are encrypted with the master password. An alias together with the master password will result in a unique "secure password." The same alias will result a different "secure password" if you use another master password, so the master password is the key to your "secure passwords." The master password should be secret If you change the master password, all generated "secure passwords" will also be changed.This behavior can be used, for example, to renew the "secure passwords" on the basis of your existing aliases Passwords.
For example, with the alias "ebay" results with the master password: "abc" the secure password: "tSwM7TFw". Changing the master password to "cba" the secure password for the alias "ebay" will be: "zfbkKTJA".
The master password is double-encrypted only stored on your device and never shared. This ensures that nobody can generate your "secure passwords" outside your device.
