怎么查看Navicat已連接保存的數據庫密碼？下面本篇文章給大家介紹一下查看navicat已保存密碼的方法，希望對大家有所幫助！

在使用Navicat 是都是習慣性的保存了密碼，久而久之后 就會忘記數據庫密碼， 這就很不舒服了，

但是，這有個技巧，可以查看navicat 已連接保存的密碼

首先去 導出連接

導出連接獲取到 connections.ncx 文件

這里記著 導出密碼！！！ 不然導出的文件里不包含加密的密碼

然后找到 文件里 password 字段的值

把他復制出來

開始破譯密碼

多虧一位Github上的大佬寫了個程序；可以直接破解這個加密密碼

程序是php的；如果本地沒裝php也沒關系 , 直接找個在線運行的工具 https://tool.lu/coderunner/

把代碼粘上去就行了

然后把剛復制的 加密密碼 替換倒數第二行 里的值 , 然后運行就行了
