第一步,找到数据库连接登录密码(密文显示)

方案一,用 navicat 导出连接,查看密码(推荐)

文件 > 导出连接

选择要导出的连接,勾选导出密码

这样就得到了加密显示的连接密码

方案二,通过注册表查看加密显示的密码

按快捷键 Win+R 在弹出的运行窗口中输入 regedit 点击确定 打开注册表编辑器

image-20211109143350339

找到 计算机\HKEY_CURRENT_USER\SOFTWARE\PremiumSoft\NavicatMSSQL\Servers

Servers 目录下就是保存在本地的连接

双击右侧Pwd 即可赋值加密显示的密码字符串
