About password generator
A strong password is the foundation of security on the internet. But it's hard to come up with one yourself: the human brain is bad at generating randomness. That's why password generators are used. Our generator creates passwords right in your browser using a cryptographically secure random number generator.
Passwords are not sent to server — they are generated in your browser and not transferred anywhere. This means that even we can't see them. This is critically important: if a password were generated on a server, it could be intercepted.
What the generator can do
- Length setting: from 6 to 128 characters.
- Character selection: lowercase, uppercase, digits, symbols.
- Exclude similar: remove 0 and O, l and 1 to avoid confusion.
- No repeats: each character is used only once.
- Strength check: assessment of password reliability and crack time.
- Cryptographic strength: crypto.getRandomValues() is used.
How to use
- Set length and character set.
- Click "Generate".
- Copy password to clipboard.
- Save it in a password manager.
