Frequently Asked Questions

Find answers to common questions about this tool.

Are the generated passwords truly random?

Yes. The generator uses crypto.getRandomValues() from the Web Crypto API, which is cryptographically secure. Pseudo-random generators like Math.random() are not used.

What character sets are available for custom passwords?

You can toggle uppercase (A-Z), lowercase (a-z), digits (0-9), and symbols (!@#$%^&*). Each selected set contributes equally to the character pool.

How does the passphrase mode generate words?

Passphrases are generated from a 56-word EFF-style wordlist. Each word is randomly selected, giving approximately 5.8 bits of entropy per word.

What is the minimum and maximum password length?

Random passwords can be 6 to 64 characters. Passphrases use 3 to 8 words. PINs range from 4 to 12 digits.

Does the generator avoid ambiguous characters like 0/O/1/l?

Toggle "No Ambiguous" to exclude characters that look similar (0, O, o, 1, l, I). This reduces the character pool but improves readability.

Can I prevent repeated characters in the generated password?

Yes. Toggle "No Repeating Chars" to prevent the same character from appearing consecutively. The generator retries if a character repeats.
