Frequently Asked Questions
- Is this password generator safe to use?
- Yes! It utilizes window.crypto.getRandomValues (the highest standard of cryptographic randomness). Passwords are never sent across the internet.
- Are generated passwords saved in your database?
- Never. EverydayTools has no backend database. Passwords exist only in your local browser memory until you copy or refresh.
