Frequently Asked Questions
Why are common passwords dangerous?
Attackers try common passwords first. If your password is in the top 1000 most used passwords, it can be cracked in under a second.
My password is not common. Is it safe?
Not being common is necessary but not sufficient. Also check strength, length, and entropy.
