The following tutorial column of phpmyadmin will introduce to you the solution to the problem that phpMyAdmin cannot log in to the MySQL server/empty password login is prohibited. I hope it will be helpful to friends in need!

System: Windows

The error is as follows:


After consulting some information, Some methods are as follows:

Step1: Modify the following fields in config.default.php of F:\xampp\phpMyAdmin\libraries.

Step1:$cfg['Servers'][$i]['password'] = ''; //Modify this field to empty

         

Step2:$cfg['Servers'][$i]['nopassword'] = true;//Modify this field to true

             

Step3:$cfg['Servers'][$i]['AllowNoPassword'] = true;//Modify this field to true

         

#Step4: The root user can log in with a blank password. Remember to change the root user’s password.


But after modifying it, I still can’t log in. Another method is as follows:

Step1: Log in to phpMyAdmin using another super user’s account and password

Step2:

Step3: Choose to change the password


Step4: Fill in the password and Re-enter and click Execute. Don't click to generate a password! ! !


Step5: After the modification is successful, the following information will be displayed:


Step 6: The root user needs to have a user whose Host is localhost. (I don’t know why I failed to create a user using phpMyAdmin)

                            Create a new user in PHPMyAdmin: grant all privileges on *.* to 'root'@'localhost' identified by "newpassword" with grant option;


Step7: Change # in F:\xampp\phpMyAdmin\libraries\config.default.php

##                                                                                                                                                                                                                                                                                                      through ]['password'] = 'newpassword';

Where newpassword is the password of the root user. Restart Apache and mysqld.exe, and use the new account and password to log in to phpMyAdmin.
