client does not support authentication protocol requested by server;consider upgrading mysql client

Mysql8.0使用低版本Navicat Premium報這個錯，應為加密方式不一樣了，我們需要需改加密的方式

到mysql的bin檔案下Shift + 滑鼠右鍵選擇運作程式視窗 輸入指令

mysql -u root -p

mysql>ALTER USER ‘root’@‘localhost’ IDENTIFIED WITH mysql_native_password BY ‘你的密碼’;

mysql>FLUSH PRIVILEGES;

mysql>quit

就可以了在連接配接Navicat Premium
