Frequently Asked Questions
What makes a strong password?
Length matters most: aim for at least 16 characters, mixing uppercase, lowercase, numbers, and symbols. Avoid dictionary words, names, and dates. A random 16-character password with all four character types has about 100 bits of entropy, which is effectively impossible to brute-force with today's technology.
Are these passwords safe to use?
Yes. Every password is generated entirely in your own browser using the cryptographically secure random source (Web Crypto), and nothing is ever sent over the internet or stored. Still, use a unique password for each account and keep them in a reputable password manager.
What is password entropy?
Entropy, measured in bits, estimates how unpredictable a password is: bits = length × log₂(size of the character pool). Each extra bit doubles the number of guesses needed. Under about 40 bits is weak, 70+ is strong, and 100+ is very strong.
