Guide: Password Generator
↑ Back to toolWhat is this tool?
This password generator creates strong random passwords, memorable passphrases, pronounceable passwords, and PINs entirely in your browser. Choose from four modes: Random for character-based passwords (8–64 characters, uppercase, lowercase, numbers, symbols), Passphrase for word-based passwords (e.g. correct-horse-battery-staple), Memorable for pronounceable fake words (e.g. bakimo72!), or PIN for numeric codes (4–12 digits). All randomness uses the Web Crypto API (crypto.getRandomValues()) — nothing is sent to any server. Use presets for login passwords or API keys, then copy with one click.
Why use a password generator?
Weak or reused passwords are the leading cause of account takeovers and data breaches. A strong password should be long, random, and unique per service. This tool gives you one-tap generation with sensible defaults, optional control over length and character sets, and no sign-up or tracking. Generate secure passwords for logins, API keys for development, passphrases when you need something memorable, or PINs for codes — all in one place, client-side only.
For accounts & logins
- • Strong login passwords (16+ chars, mixed character sets)
- • Memorable passwords for services you type often
- • Passphrases for password managers or recovery
For developers
- • API keys and secrets (long alphanumeric)
- • Environment variables and config values
- • Bulk passwords for test accounts
Key features
- Four modes — Random (length 8–64, character set chips, exclude ambiguous), Passphrase (3–8 words, separator, capitalize, add number), Memorable (3–6 syllables, pronounceable words + optional number/symbol), PIN (4–12 digits).
- Presets — Login password (16 chars, all character sets) and API key (32 chars, alphanumeric) for one-click generation.
- Strength & entropy — Real-time label (Weak / Fair / Strong / Very strong) and approximate bits of entropy so you know how secure the password is.
- Chips & sliders — Toggle character sets and options with chips; adjust length, word count, syllables, or digits with minus/plus buttons and a slider.
- Generate multiple — Create 2–20 passwords at once and copy as a newline-separated list (e.g. for bulk test accounts).
- 100% client-side — Generated in the browser using
crypto.getRandomValues(); nothing is sent to or stored on our servers.
Modes explained
Each mode produces a different style of password suited to different needs.
- Random — Classic mix of uppercase, lowercase, numbers, and symbols. Best for login passwords and secrets when you use a password manager. Option to exclude ambiguous characters (0, O, 1, l, |) for easier typing.
- Passphrase — Several dictionary words with a separator (e.g. hyphen or space), optionally with a number. Easier to remember than a random string while still strong if you use enough words (e.g. 5+).
- Memorable — Pronounceable fake words built from syllables (e.g. bakimo, kovu), with optional number and symbol. Good when you need something strong but easier to type or remember than a long random string.
- PIN — Numeric only (4–12 digits). Use for PIN codes, short verification codes, or temporary numeric secrets. Not suitable as a primary account password.
How this tool works (step-by-step)
- Select a preset (Login password or API key) or pick a mode (Random, Passphrase, Memorable, PIN). A password is generated automatically.
- Click Copy to copy the password to your clipboard, or click the refresh icon to generate another without changing options.
- Open Options (collapsible) to change length, character sets (via chips), word count, syllables, separator, or PIN length. Use the minus/plus buttons and slider for numeric settings.
- Use Generate multiple to create 2–20 passwords at once; they are copied as a list (one per line) for bulk use.
Example outputs
Depending on the mode and options, you might get outputs like these (do not use these; generate your own):
- Random (login): K9#mP2$xLq7vNw4j
- Passphrase: correct-horse-battery-staple-42
- Memorable: bakimo72!
- PIN (6 digits): 847291
Best practices
- Use a password manager to store generated passwords; avoid reusing the same password across sites.
- For logins, prefer Random mode with at least 16 characters and all character sets enabled.
- For passphrases, use at least 5 words and consider adding a number or symbol for extra strength.
- Exclude ambiguous characters when you need to type the password by hand (e.g. on a TV or game console) to reduce mistakes.
- Never share a generated password over email or chat; use a secure channel or password manager sharing.
FAQ
- Is it safe to use this password generator?
- Yes. Passwords are generated in your browser using the Web Crypto API (crypto.getRandomValues). They are never sent to or stored on our servers. We do not log or transmit generated passwords.
- What is the difference between passphrase and memorable?
- A passphrase uses real dictionary words (e.g. correct-horse-battery-staple). Memorable mode builds pronounceable fake words from random syllables (e.g. bakimo72!). Both can be strong; passphrases are easier to remember, memorable passwords are shorter and easier to type.
- What is a strong password?
- A strong password is long (e.g. 16+ characters for random, 5+ words for passphrase), uses a mix of character types when applicable, and is unique to each account. The tool shows an approximate entropy (bits) and a strength label (Weak to Very strong) to help you judge.
- Why exclude ambiguous characters?
- Characters like 0/O, 1/l/| look similar and are easy to mix up when typing. Excluding them reduces errors while still giving strong entropy. Use this option when you type the password manually on devices with small or unclear keypads.
- Can I generate multiple passwords at once?
- Yes. Use the "Generate multiple" section: set a count (2–20), then click the button. The list is copied to your clipboard, one password per line, so you can paste it into a spreadsheet or script for bulk account creation.
