Frequently asked questions about the password generator
Are the passwords really random?+
Yes. They are produced by your browser's crypto.getRandomValues API, the same cryptographically secure generator used for encryption keys - not by a predictable Math.random sequence.
Is the password sent anywhere?+
Never. It is generated on your device, exists only in the page, and disappears when you close the tab. Nothing is logged or transmitted.
How long should a password be?+
Use at least 16 characters with mixed types for important accounts. Length matters more than complexity: a long random password is far harder to crack than a short one full of symbols.
Is this tool free to use?+
Yes, completely. There is no account, no trial, no watermark and no daily limit. Data Wave Cloud is funded by unobtrusive advertising so the tools stay free permanently.
