It's a good idea to change passwords now and then. I recommend using a password manager to keep track of them all. Most browsers also have a "remember password" feature.
Also fill in your e-mail address in case you forget the password.
And never give away your password to anyone, and never login to someone else's account even if they ask you to. It will get both of you banned.
To increase the security a little, it's been possible to access the game via SSL/HTTPS for a while and I soon plan to redirect all traffic to HTTPS. So try the game from httpS://visual-utopia.com/
(notice the S in https:) And message me if it doesn't work.
Also note that our security is not much better then Facebook, Linkedin, et. al, so if you use the VU password somewhere else, go change it there too!
Tips for a strong password. 1) Use a password manager 2) If you don't want to use a password manager you should pick a long remember-able password with weird characters in it like едц.
