I newly installed MySQL today, but Navicat could not connect, so I reported this error directly. After surfing the Internet for a while, I finally found the reason and solution.

Reason: After analyzing and searching for relevant information, I found new features of MySQL 8.0 and adopted a new and safer authentication method, caching_sha2_password

solution:

1. Enter the CMD command window (win+R)

2. Enter the bin path of the mysql installation directory and run the mysql -uroot -p command to log in (the password is the password set when installing mysql) -- (my address is: C:\Program Files\MySQL\MySQL Server 8.0\bin )

3. Enter ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'root'; (root is the user name, localhost is the ip address 127.0.0.1 is the local machine, mysql_native_password is the old password authentication mechanism, root is the password, don't forget the semicolon at the end ;)

4. Enter Navicat to test the connection

At this point, the problem is solved. If you have other questions, welcome to communicate with Xiaobian, Xiaobian QQ 907044657
