Connector/Python supports authentication plugins available as of MySQL 5.6. 
This includes mysql_clear_password and sha256_password, 
both of which require an SSL connection. 
The sha256_password plugin does not work over a non-SSL connection 
because Connector/Python does not support RSA encryption.

The connect() method supports an auth_plugin argument 
that can be used to force use of a particular plugin. 
For example, 
if the server is configured to use sha256_password by default 
and you want to connect to an account that authenticates using mysql_native_password, 
either connect using SSL or specify auth_plugin='mysql_native_password'.

auth_plugin='mysql_native_password'
