Strong Password Generator

Generate a strong, random password instantly — right in your browser, with no data sent to any server. Choose your desired length, select which character sets to include, and copy the result with one click. Need multiple passwords at once? Generate up to 20 in a single batch.

How to Use

1. Drag the Password Length slider to your preferred length — 8 characters for basic accounts, 16 for most logins, 32 or higher for database credentials and API keys
2. Tick the Character Sets you want — Uppercase, Lowercase, Numbers, and Symbols are all enabled by default
3. Your password generates automatically; click Regenerate any time to get a new one
4. Check the Strength indicator — aim for Strong or Very Strong before using the password
5. Click Copy to copy the password to your clipboard — paste it directly into your password manager
6. To generate multiple passwords at once, set the Generate Multiple count and click the batch button — then use Copy All or copy each individually

Password Length Guide

For any account that protects sensitive data — banking, email, work systems — use at least 16 characters with all four character sets enabled.

What Makes a Password Strong?

Password strength is measured by entropy — how unpredictable the password is to an attacker running a brute-force or dictionary attack. Four factors drive entropy:

Length is the single most impactful factor. Each extra character multiplies the number of possible combinations. A 16-character password with only lowercase letters is statistically harder to crack than an 8-character password with all four character sets.

Character set diversity increases the pool of possible characters per position. Adding symbols to a purely alphanumeric password roughly triples the search space per character.

True randomness eliminates patterns. This generator uses crypto.getRandomValues() — the same cryptographic API used by browsers for TLS key generation — ensuring each character is genuinely unpredictable, not pseudo-random.

No dictionary words — human-chosen passwords frequently contain names, dates, and words that attackers test first. A randomly generated password avoids all predictable patterns.

Common Use Cases

• Password managers — Generate a unique, random password for every account. Store it in your manager (Bitwarden, 1Password, Dashlane) — you only need to remember one master password
• System administrator accounts — Use 24+ character passwords with all character sets for root, admin, and service accounts
• Database credentials — Generate 32–64 character passwords for database users; the password is never typed by hand, so length is no burden
• API keys and secrets — When a service lets you set your own shared secret or webhook token, generate a 32-character random password
• Temporary access — Batch-generate 10–20 one-time passwords for event wifi, guest accounts, or temporary staff access
• Passphrase replacement — For accounts that require a password (not a passphrase), a 20+ character random string provides equivalent or better entropy

Tips for Best Results

• Always store generated passwords in a password manager — never in a text file, email, or spreadsheet
• Enable all four character sets unless the target system explicitly forbids symbols — many systems allow !@#$%^&* but reject others; test first
• If a site rejects your password due to symbol restrictions, uncheck Symbols and regenerate rather than manually editing the password
• Use batch mode to generate passwords for a set of accounts in one session — copy all, paste into your password manager's import format
• After generating a password for a critical account (email, banking), copy it immediately into your manager before closing the tab
