How to use Password Generator

A strong, unique password is your first line of defence against account compromise and data breaches. This generator uses your browser's cryptographically secure random number generator — crypto.getRandomValues — to produce passwords that are genuinely unpredictable and cannot be reverse-engineered. Use the length slider to set your password length between 6 and 128 characters; security experts recommend at least 16 characters for any important account. Toggle the character set checkboxes to include or exclude uppercase letters (A–Z), lowercase letters (a–z), numbers (0–9), and symbols such as !@#$%^&*. At least three of the four character types should be enabled for strong passwords. Enable Exclude Ambiguous Characters to remove visually confusing pairs like 0 (zero) and O (letter O), l (lowercase L) and 1 (one), I (capital i) and l — especially helpful when you need to type the password manually on a device without clipboard access. Set the Count to generate up to 10 different passwords simultaneously so you can pick the one that feels right or use different ones for different accounts. Click the copy icon next to any password to copy it instantly. The strength meter rates each password from Weak to Very Strong based on length and character variety. Click Generate to refresh all passwords. Pro tip: use a reputable password manager to store generated passwords so you never need to memorize them or reuse passwords across accounts.

Frequently Asked Questions

How long should my password be?

Security experts recommend at least 16 characters for important accounts such as email, banking, and cloud storage. Every additional character exponentially increases the total number of possible combinations — a 16-character password using all four character types has more than 10²⁹ possible values, making brute-force attacks computationally infeasible even with modern hardware.

Are generated passwords stored anywhere?

No. Passwords are generated client-side using your browser's built-in Web Crypto API (crypto.getRandomValues), which is the same cryptographic standard used by browsers for TLS. Passwords are displayed on screen only — they are never transmitted to any server, never logged anywhere, and never stored in local storage or cookies. Close the tab and they are gone permanently.

What does excluding ambiguous characters do?

Excluding ambiguous characters removes character pairs that look similar in many fonts and at small sizes: 0 (zero) and O (capital O), 1 (one) and l (lowercase L), and I (capital I) and l (lowercase L). This prevents transcription errors when you need to type a password manually on another device. It has no negative impact on password security — the remaining character set is still very large.

Is it safe to use an online password generator?

Yes, provided the generator runs entirely in your browser — which this one does. Because no network request is made when generating passwords, there is no server that could intercept or log the output. Be cautious of generators that require an account, collect your email, or make any server requests when you click Generate.

What makes a password strong?

A strong password has four properties: sufficient length (16 or more characters), character variety (uppercase, lowercase, numbers, and symbols), true randomness (no dictionary words, names, dates, or predictable patterns), and uniqueness (never reused across different accounts or services). The strength meter on this tool evaluates all four criteria and gives you an instant rating.
