In this primer I will show how to improve the security of your MariaDB installation by using two-step verification and how to use it from your Windows GUI client.
Let’s suppose you have your data in MariaDB, installed, say, on Ubuntu. And your users connect to it to run ad hoc queries, using some sort of a Windows GUI client. You don’t want them to write the access password on post-it notes or have it auto-entered by the client. And you don’t want anyone see the password when one of the salespersons connects to the mother ship from his laptop in the Internet café. So you decide to use the two-step verification, just like Google does, to secure the access to the data.
