PhpMyAdmin error requested authentication method unknown to the client [caching_sha2_password]
PhpMyAdmin error requested authentication method unknown to the client [caching_sha2_password]


This error comes due to authentication problem. When you  try to login into MySQL by terminal, you  get the success . But when you try to login with PhpMyAdmin this error comes.

To fix this issue you have to do ALTER user in table and provide complex password. Below is the two line of command that you have to enter into MySQL database.

Replace your user and user_password with your own.

mysql> ALTER USER ‘user’@’localhost’ IDENTIFIED WITH   mysql_native_password BY ‘user_password’;

mysql> FLUSH PRIVILEGES;

mysql> exit

If above is not fixed your error/issue then create a new user with grant privileges and login with new credentials.


mysql> create user ‘vetechno’@’localhost’ identified by ‘vetechno@@1234’;

mysql> grant all privileges on . to ‘vetechno’@’localhost’;

mysql> ALTER USER ‘vetechno’@’localhost’ IDENTIFIED WITH mysql_native_password BY ‘vetechno@@1234’;

mysql> FLUSH PRIVILEGES;

mysql> exit

 

Conclusion

I hope this tutorial post has helped you to fix the [caching_sha2_password] on Ubuntu 18.04 LTS. Please feel free to ask your queries if you are facing any difficulties when creating new user on mysql.
