Question 1

Is this password generator really secure?

Accepted Answer

Yes. Passwords are generated using the browser's built-in crypto.getRandomValues() API — a cryptographically secure pseudo-random number generator (CSPRNG). Your password is never sent to any server; everything runs locally in your browser.

Question 2

How long should my password be?

Accepted Answer

For most accounts, 16–20 characters with mixed character types gives over 100 bits of entropy — far beyond what any attacker can crack. For highly sensitive accounts (banking, email), aim for 24+ characters or use a passphrase of 6+ words.

Question 3

What is password entropy?

Accepted Answer

Entropy measures unpredictability in bits. A password with N bits of entropy requires an attacker to test up to 2^N combinations. Each extra character multiplies the search space by the pool size. 80+ bits is considered very strong.

Question 4

What is a passphrase and why use one?

Accepted Answer

A passphrase is several random words joined together (e.g. marble-vortex-castle-eagle). It is easier to remember than a random string but just as strong — 5 words from this 152-word list gives ~37 bits. Add a number or symbol for extra strength.

Question 5

Should I exclude ambiguous characters?

Accepted Answer

Only if you need to type the password manually. Characters like 0, O, 1, l, I look similar in many fonts. Excluding them slightly reduces entropy but prevents typos. For copy-pasted passwords, leave them in for maximum randomness.

Question 6

What is the custom symbol set for?

Accepted Answer

Some websites restrict which symbols are allowed in passwords. Use the custom symbols input to enter only the symbols your target site accepts (e.g. !@#$%) instead of the full default set.

Question 7

How should I store my passwords?

Accepted Answer

Use a dedicated password manager — Bitwarden (free, open-source), 1Password, or Dashlane are excellent options. Never store passwords in plain text or spreadsheets. Enable two-factor authentication (2FA) on your password manager account.
