The passphrase mode generates passwords like "correct-horse-battery-staple" style phrases. Much easier to memorise than random strings and still highly secure. The crypto randomness is reassuring.
Password Generator⭐⭐⭐⭐⭐
I use the batch generate feature to get 10 strong passwords at once for a new project. Click to copy any of them instantly. The exclude ambiguous option is essential for passwords typed from memory.

The PIN mode is perfect for when I need a numeric code. The memorable mode with mixed case and digits produces passwords that are actually memorable. Best free password generator I've used.
Password Generator⭐⭐⭐⭐⭐
I appreciate that the security is based on window.crypto — real CSPRNG, not Math.random(). The strength indicator updates as I adjust the options so I can see the security impact of each choice.

❓ FAQ
What makes a password cryptographically secure?+
This generator uses window.crypto.getRandomValues() which accesses the operating system's CSPRNG (Cryptographically Secure Pseudo-Random Number Generator). This is suitable for generating encryption keys, tokens and passwords — unlike Math.random() which is not cryptographically secure.
What is a passphrase and why is it secure?+
A passphrase is 4–6 random words joined by separators (e.g. "tiger-cloud-piano-river"). With a 10,000 word dictionary, 4 words give 10^16 combinations — stronger than a random 12-char password and far more memorable.
How long should my password be?+
For general accounts: 16+ characters. For financial accounts: 20+ characters. For encryption keys and master passwords: 24+ characters with all character sets. Length matters more than complexity.
Should I use a password manager?+
Yes. Use this tool to generate strong passwords, then store them in a password manager (Bitwarden, 1Password, KeePass). Never reuse passwords — each account should have a unique one.
What are ambiguous characters?+
Characters that look similar: 0 and O, 1 and l and I. Excluding them prevents transcription errors when passwords are typed manually rather than copy-pasted.
