Choosing strong passwords cannot be stressed enough.

Remember to use letters, numbers and characters if you can. DON’T use password, p@55w0rd, letmein or a word straight out of the dictionary. Something like jIUhs8&645#j is darned near impossible to hack. Such a large percentage of users are blisfully unawares of things like brutforce attacks.

There’s this great website for generating password: http://strongpasswordgenerator.com/

Lastly, DON’T use the “Remember me” feature on websites unless you are well aware of who has access to the machine you are on. Honestly, they just make it so much easier for an attacker. Instead, use the browser’s “Remember me” feature if you HAVE to.
