I downloaded MySQL 8.0 today and found that Navicat could not connect and always reported error 1251;

The reason is that the encryption method of MySQL 8.0 version is different from that of MySQL 5.0 , the connection will report an error.

After trying many methods, I finally found one that can be implemented:

Change the encryption method

1. First enter the mysql root account through the command line:

PS C:\Windows\system32> mysql -uroot -p

Copy after login

Then enter the root password:

Enter password: ******

// If an error is reported ERROR 1396 (HY000): Operation ALTER USER failed for 'root'@'%':

The remote access permission is not Correct, select the database first, check it and then change it:
