+# Set/Reset MySQL Root Password on MySQL 14.14
+
+I was trying to setup MySQL that I installed using `sudo apt install MySql` and couldn't remember how to set the root password. I found many different instructions on how to stop MySQL, boot into safe mode and reset the root password.
+
+*None of them worked.*
+
+This did:
+
+Run: `sudo mysql_secure_installation`
+
+You will see something like this:
+
+```
+Securing the MySQL server deployment.
+
+Enter password for user root:
+```
+
+You can setup a password strength validation plugin if you wish in the next step:
+
+```
+VALIDATE PASSWORD PLUGIN can be used to test passwords
+and improve security. It checks the strength of password
+and allows the users to set only those passwords which are
+secure enough. Would you like to setup VALIDATE PASSWORD plugin?
+
+Press y|Y for Yes, any other key for No:
+```
+
+Next, it will give you an option to disable anonymous users. Do it. It is a security liability if you don't.
+
+```
+By default, a MySQL installation has an anonymous user,
+allowing anyone to log into MySQL without having to have
+a user account created for them. This is intended only for
+testing, and to make the installation go a bit smoother.
+You should remove them before moving into a production
+environment.
+
+Remove anonymous users? (Press y|Y for Yes, any other key for No) :
+```
+
+Remote root login to MySQL is generally not a good thing. I recommend disabling it:
+
+```
+Normally, root should only be allowed to connect from
+'localhost'. This ensures that someone cannot guess at
+the root password from the network.
+
+Disallow root login remotely? (Press y|Y for Yes, any other key for No) :
+```
+
+Delete the test database to reduce the attack surface for hackers:
+
+```
+By default, MySQL comes with a database named 'test' that
+anyone can access. This is also intended only for testing,
+and should be removed before moving into a production
+environment.
+
+
+Remove test database and access to it? (Press y|Y for Yes, any other key for No) :
+```
+
+Reload privilege tables now, unless you need MySQL working for this precise instant. It only takes a second.
+
+```
+Reloading the privilege tables will ensure that all changes
+made so far will take effect immediately.
+
+Reload privilege tables now? (Press y|Y for Yes, any other key for No) :
+```
+
+And you're done!
