What makes a password strong
Length beats cleverness. Every added character multiplies the guessing work, which is why a random 16-character password (~100 bits of entropy) is effectively uncrackable while "P@ssw0rd2024!" falls to pattern-aware crackers in minutes. This generator uses your browser's cryptographically secure randomness (crypto.getRandomValues) — passwords are created on your device and never transmitted; you can even use it offline.
Best practice: a unique random password per site, kept in a password manager, with two-factor authentication on anything important. The "avoid look-alikes" option drops 0/O and 1/l/I for passwords you'll have to read or type manually.
Frequently asked questions
Is it safe to generate passwords on a website?
This one runs entirely client-side — the password is produced by your own browser's crypto engine and never sent over the network. Load the page, disconnect from the internet, and it still works.
How long should my password be?
16+ random characters for anything that matters. For a master password you must memorise, a 5-6 word random passphrase is both strong and typeable.
