MySQL error authentication plugin 'caching_sha2_password' is not supported in Python

Dung Do Tien Nov 16 2021 841

Hello, I have created a project web with Python and MySQL.

I have written some lines of code as below to help me open to connect to MySql

My code:

 import mysql.connector as sql
con = sql.connect(host="", user="sa", passwd="my_pass", database="students")

if con.is_connected() == false
   print("Cant not connect to My SQL")

But when running that code I got an exception throw Authentication plugin 'caching_sha2_password' is not supported.

MySQL error authentication plugin 'caching_sha2_password' is not supported

Anyone can explain to me why it throws and how can I solve it?

Thanks for any idea.

    You can add more auth_plugin='mysql_native_password' pram in the connection string as below:

    Replace this line code:

     con = sql.connect(host="", user="sa", passwd="my_pass", database="test")


     conn = mysql.connector.connect(user='root', password='password', host='',port=5000,database='test',

    I hope it works for you.

    Do you install mysql-connector?


      pip uninstall mysql-connector

    and run

     pip install mysql-connector-python

    And finally, try to run again your code.
