Question 1

How strong should my password be?

Accepted Answer

Aim for at least 16 characters mixing uppercase, lowercase, digits, and symbols - roughly 90+ bits of entropy. The strength meter estimates entropy from length and character variety.

Question 2

What is a passphrase and why use one?

Accepted Answer

A passphrase is a sequence of random words, like 'Canyon-Mosaic-Lantern-42'. It is easier to remember and type than a random string while providing comparable strength - the approach recommended by the EFF and NIST.

Question 3

Are generated passwords truly random?

Accepted Answer

Yes. The generator uses the browser's cryptographically secure random number generator (crypto.getRandomValues), the same source used for TLS keys, with rejection sampling to avoid bias.

Question 4

Is my password sent anywhere?

Accepted Answer

No. Passwords are generated locally in your browser and are never transmitted, logged, or stored. The tool cannot see or retain what you generate.

Question 5

What characters are ambiguous?

Accepted Answer

Ambiguous characters look similar in many fonts: 0 and O, 1 and l, and I and |. Excluding them makes passwords easier to read aloud, print, or type on a phone.

Question 6

Should I use a password manager instead?

Accepted Answer

Yes - use a password manager to store generated passwords. This generator is ideal for creating credentials that then live safely in your manager or device keychain.
