Answer 1

Best thing to do is to reset your user password to the new hashing algorithm

With workbench: http://blogs.technicise.com/change-root-password-in-mysql-workbench/

Command line: http://www.cyberciti.biz/faq/mysql-change-root-password/

Answer 2

Using the way like rayVenues but you should change your password connection, it will work fine :)

Answer 3

On the command line, use something like the following, if you have no choice...

mysql -uTheUseerNAme -pThePassword DbName -h HostName --skip-secure-auth

Hope this helps someone, as this was my problem connecting from a Linux box

Answer 4

For MySQL Workbench 6.08 in the Manage Server Connections, Connection tab, Advanced sub-tab you must check the box 'Use the old authentication protocol.'

Answer 5

I've got same problem in Centos 7 with MySQL. If i try to connect by mysql client:

ERROR 2049 (HY000): Connection using old (pre-4.1.1) authentication protocol refused (client option 'secure_auth' enabled)

Bu in my case if I specify:

--skip-secure-auth

it cause error message:

ERROR 1275 (HY000): Server is running in --secure-auth mode, but 'root'@'localhost' has a password in the old format; please change the password to the new format

It work only when i specify:

in /etc/my.cnf

[mysqld]
...
secure_auth=false

and then restart mysqld

Answer 6

I had similar issue, but using MAC Terminal connecting remote MySQL db.

Solution: I create a new user with less special characters, that problem disappeared.
