I can't login to my own Minecraft server?

I recently created a hamachi server on my PC. I wanted to login and build some stuff on it but whenever I try to login it just says:

Connection lost, failed login: bad login
Here is my server.properties file, if it helps:

#Minecraft server properties

What is a Minecraft and what does it do?

Not worth creating a hamachi server. You shouldn't even bothering on creating one, if you want to create a server so bad you should definitely go ROOT.

Make sure you're client and server version are the same (up to date doesn't matter).
