I was doing internet-type things and stuff when I stumbled across this clean, simple, and useful website:
It’s simple. You type in your password and it estimates how long it would take a standard desktop PC to guess your password based on the length, words, characters, and numbers that you’ve entered.
Even better, it tells you what you should fix. It will say if it’s too short, or if you need more characters, or if it shouldn’t be based off of a word. It tells you how secure your password is then tells you how to make it even more secure.
It also has a database of the most common passwords that it compares to. So if your password is under that category, you might want to seriously reconsider your online security situation.
And their font is nice.
