About Password Generator
Weak passwords are usually short, predictable, or reused — this tool avoids all three by generating long, random passwords from your browser's cryptographically secure random number generator, the same source browsers use for security-sensitive operations.
Choose your length, pick which character types to include, and optionally exclude look-alike characters that are easy to mistype. The live strength meter estimates entropy so you can see the effect of each option immediately, and five extra suggestions are generated below in case you want a choice.
Because everything happens locally with no network call at all, your new password is never transmitted anywhere before you copy and use it.
Frequently asked questions
Is this actually secure, or just a random-looking generator?
It uses the Web Crypto API (crypto.getRandomValues), the same secure randomness browsers use for cryptography — not Math.random, which is not safe for passwords.
Are my generated passwords sent anywhere?
No. There is no network request in this tool at all — the password is created and shown entirely on your device.
What does the strength meter measure?
It estimates entropy from the password's length and the character set you selected, then maps that to Weak, Fair, Strong or Very strong.
What does 'exclude ambiguous characters' do?
It removes characters that look similar and are easy to mistype or misread, like 0/O and 1/l/I.
How long should my password be?
16 characters or more with all character types enabled is a good default for most accounts; use the maximum length a site allows where possible.
