In this long blog I try to sum-up some features which you should disable before running MikroTik in any environment. First of all is an `backup` interface, so in case you lock yourself up, you will always have a way to login. Other points include creating custom user, disabling unused services in various places throughout the RouterOS and if you don't need IPv6 then disable it too just in case 😉.

MikroTik has a simple interface for managing certificates, but lacks the ability to notify you when such cert expires. For this reason I created a simple script insipired by forum question and modified for my purpose.

Managing your passwords through third parties isn't always the best practice, therefore I use vaultwarden, which can be deployed on my own infrastructure without subscription and need for external provider.
