Strong Password Generator - Free & Secure

A strong password generator builds random, complex passwords that are hard to guess and easy to copy. This tool mixes uppercase, lowercase, numbers, and symbols in any length you set. It never sends data to a server, so your new passwords stay on your device. Use it to stop password reuse and lower breach risk across your accounts.

1. Choose length: Select how many characters you need; 16 or more is recommended for high-value accounts.
2. Select character sets: Toggle uppercase, lowercase, numbers, and symbols. Exclude lookalikes like O/0 and l/1 if needed.
3. Generate and copy: Click Generate to see a password, then copy or download it. Regenerate until it fits your policy.

• Security by default: Every password is random and unique, reducing reuse that attackers exploit.
• Meets policy rules: Match length and character requirements for banking, SSO, or corporate portals.
• Convenient anywhere: Works offline in your browser, so you can create passwords on locked-down networks.

Use case 1: Banking and finance logins

Set 20+ characters with mixed symbols to satisfy strict banking policies and protect funds.

Use case 2: Team password rotations

Generate batches during quarterly rotations, then store them in your team’s vault.

Use case 3: Developer secrets

Create long random strings for API keys or database users, and rotate them without manual typing errors.

Basic example

Settings: Length 16, Uppercase on, Lowercase on, Numbers on, Symbols on
Output: T9e!kfQ2%vR7bNxp

Advanced example

Settings: Length 24, Uppercase off, Lowercase on, Numbers on, Symbols off, Exclude lookalikes
Output: mrc8ydqg7vpbkz4sn62hfjw9

Password rejected by a site

Some sites ban certain symbols or require at least one of each character type. Adjust the character set and regenerate to fit the rule.

Copy failed

Browser clipboard permissions can block copying. Use the manual copy icon or download the password as a text file instead.

• Aim for 16+ characters for accounts and 24+ for admin access.
• Turn off similar characters when sharing by phone to avoid misreads.
• Pair this with the random number generator to create PINs that pass strict numeric-only rules.

• Need to store plaintext safely? Encode it with the Base64 encoder before saving in config files.
• Convert credentials into hashes using the MD5 hash generator when you need non-reversible checksums.

Passwords are created locally in your browser with cryptographic randomness. Nothing is sent or stored on servers, so your new credentials remain private.
