Trying to log into Sequel Pro

I'm brand new tp programming.

I'm watching the titled: Intro to PDO. URL: https://laracasts.com/series/php-for-beginners/episodes/13?autoplay=true

I downloaded MySQLworkbench - I'm able to login fine there.

When I try to connect to Sequel Pro - This is the error I get:

Connection Failed

Unable to connect to host 127.0.0.1, or the request timed out.

Be sure that the address is correct and that you have the necessary privileges, or try increasing the connection timeout (currently 10 seconds).

MySQL said: Authentication plugin 'caching_sha2_password' cannot be loaded: dlopen(/usr/local/lib/plugin/caching_sha2_password.so, 2): image not found

What should I do?
