How it works
Random bytes from the browser CSPRNG pick characters from your selected sets.
At least one character from each enabled set is included, then the rest is filled and shuffled.
Good passwords
Long, unique passwords per site plus a password manager beat short memorable ones.
Privacy
Generation happens locally. Clear the field when done on shared computers.
Common questions
- Is this randomness secure?
- It uses the browser’s cryptographic RNG, suitable for passwords.
- Minimum length?
- Eight characters minimum here; longer is better (often 16+).
- Why include symbols?
- Larger alphabet shortens the password needed for the same entropy when the site allows them.
- Should I memorize these?
- Prefer a password manager rather than reusing or memorizing many random strings.
