How to use the password generator
- Choose a length (12+ is recommended; 16+ is strong).
- Toggle uppercase, lowercase, numbers and symbols.
- Click Generate, then Copy and paste it into your password manager.
What makes a password strong
- Length beats complexity — every extra character multiplies the cracking time.
- Randomness — avoid names, dates, or dictionary words.
- Unique per account — never reuse passwords across sites.
- Use a manager — so you never have to memorize them.
Benefits
- Every password is generated on your device and never sent over the internet.
- You control the length and which character types are included, so you can meet any site’s rules.
- Produces high-entropy, truly random passwords that are far harder to guess or brute-force than anything human-made.
- Instant and unlimited — generate a fresh one for every account.
Limitations to know
- A strong password only helps if you can store it safely — you will need a password manager to remember long random strings.
- It does not check whether a password has appeared in a known data breach.
- Strength depends on the length and character variety you choose; a short password is weak no matter how random.
Common mistakes to avoid
- Picking a short length for convenience — aim for at least 16 characters where the site allows it.
- Reusing one strong password across multiple sites, which turns a single breach into many.
- Saving passwords in a plain notes file or an unprotected browser profile instead of a dedicated manager.
- Removing symbols or numbers to make a password "easier" — that directly weakens it.
Alternatives
For accounts you must type by hand, a memorable passphrase of four or more random words is a good option. Note that the UUID Generator creates unique identifiers for software, not secure passwords — use this tool for anything you log in with.
