How random are the generated passwords?

Passwords are generated using the browser's WebCrypto API (crypto.getRandomValues), which is a cryptographically secure pseudo-random number generator (CSPRNG). This is suitable for generating passwords and secrets.

What are ambiguous characters?

Ambiguous characters are those that look similar in many fonts: 0 (zero) and O (uppercase o), l (lowercase L), 1 (one), and I (uppercase i). Excluding them reduces transcription errors when typing passwords manually.

What is pronounceable mode?

Pronounceable mode alternates consonants and vowels to produce passwords that sound like words and are easier to remember, such as 'botirane'. These are less random than full character-set passwords, so use them only when memorability matters more than maximum entropy.

Are my passwords stored or sent anywhere?

No. All password generation happens entirely in your browser. Nothing is stored on a server or transmitted over the network.

About this tool

Create strong, random passwords using your browser's WebCrypto API for true randomness. Control length (8–128 characters), choose character sets (uppercase, lowercase, digits, symbols), define a custom symbol set, exclude ambiguous characters, and generate up to 20 passwords at once. A pronounceable mode alternates consonants and vowels for memorable passwords. Each password is rated with a strength meter.

How to use

1 Set the desired password length using the slider (8–128).
2 Toggle character sets: uppercase, lowercase, digits, symbols.
3 Optionally enable 'Exclude ambiguous characters' or enter characters to exclude.
4 Set quantity (1–20) and click Generate, then copy individual passwords or all at once.
