Frequently Asked Questions
A strong password is at least 16 characters long and combines uppercase and lowercase letters, numbers and symbols. Avoid anything personal like names, birthdays or common words. The best approach is to use a password generator like this one so the result is truly random and unpredictable.
Security comes down to length, randomness and uniqueness. A longer password has exponentially more possible combinations, making it far harder to crack. Random characters are harder to guess than patterns or words. And using a unique password for every account means one breach can't expose everything else.
A passphrase is a sequence of random words, like "copper-falcon-river-42". It's easier to remember than a string of random characters but can still be very secure if the words are chosen randomly and there are enough of them. Security experts increasingly recommend passphrases because they balance memorability with strength.
For most accounts, 16 characters is a solid minimum. For highly sensitive accounts like banking or email, aim for 20 or more. Password length is one of the biggest drivers of security — each extra character multiplies the difficulty for an attacker enormously.
Yes. Every password is generated entirely inside your browser using your device's cryptographically secure random number generator. Nothing is ever sent to a server, stored, or logged. You can even disconnect from the internet and the tool still works.
The most commonly used weak passwords include "123456", "password", "qwerty", "abc123" and "letmein". Passwords based on your name, birthday, pet's name or favourite team are also easily guessed. Any password that appears in a dictionary or common-password list can be cracked in seconds.
Frequently Asked Questions
How long should a strong password be?
At least 16 characters. A 20-character random password is exponentially harder to crack than a 12-character one.
Are passwords stored anywhere?
No — all passwords are generated in your browser and never sent to any server.
What makes a password strong?
Length, randomness, and a mix of uppercase, lowercase, numbers and symbols. Avoid dictionary words and patterns.
Should I use a password manager?
Yes — Bitwarden (free, open source), 1Password, and Dashlane are popular options.
