master password

基本解释

FireMaster can be used to recover the master password in case you forget it.
FireMaster 可以用來恢複可能會忘記的主密碼。
Be sure to remember the master password or you will be unable to access any information protected by it!
確保記住主密碼，否則無法訪問它保護的任何信息！
When the system confirms that the passwords you entered match, you will see a message box that the master password has been successfully changed.
儅系統確認輸入的密碼匹配，您將看到一個提示成功脩改主密碼的消息。

That means users only need to remember one master password, which they're not likely to forget.
