How To Fix “Error Establishing A Database Connection” In WordPress after reset Mysql users passwords

Only yesterday,I received one email from my hosting provider about reminding of me the ‘preparatory task of MySql upgrade’ on their server side. They told that current mySQL database passwords are 16 bit password hash and they want to reset password so that it will become 4i bit password hash. The email also tell me that , ‘In case, if the password has not been reset to use the 41 byte password hash before 15th November, 2017 then your database driven websites will start throwing the following error message :- MySQL Errors – You must SET PASSWORD/Password hash should be a 41-digit hexadecimal number’.

They have provided one link which assists me to reset password. That email also told me that, just by replacing the password with the older password also can make this MySQL preparatory task of update better.

Further the email told me, “you can also reset the password using your existing password itself. Eg, if your existing password is “[email protected]” and while resetting you enter the new password as “[email protected]”, you do not need to update your connection strings but the password format will change from the current 16 byte hash to 41 byte hash.
In-order to avoid any interruption in the service, you need to reset the password of all MySQL database users before”.
