A Master Password is used to protect sensitive information like site passwords. If you create a Master Password you will be asked to enter it once per session when { -brand-short-name } retrieves saved information protected by the password.
主密码用于保护敏感信息（如网站密码）。创建主密码后， { -brand-short-name } 每次检索被该密码保护的信息前都要再次输入主密码。
