Free Strong Password Generator

It depends on the generator. Our tool runs 100% in your browser — your password is created using the Web Crypto API on your device. We have zero server communication for password generation. No cookies, no analytics on generated passwords, no storage. You can verify this by disconnecting from the internet and generating — it still works. Always avoid generators that require you to "sign up" or "create an account" to generate passwords.

8 characters is dangerously weak in 2025. Modern GPUs can crack an 8-character password with mixed case, numbers, and symbols in under 5 minutes. The absolute minimum should be 14 characters, but we recommend 16+ for personal accounts and 20+ for anything sensitive. Use our generator set to 18+ characters with all character types enabled for maximum security.

Both can be equally secure, but they serve different purposes. A random 16-character password has about 105 bits of entropy. A 4-word passphrase from a 7,776-word list has about 51 bits — but a 6-word passphrase reaches 77 bits. The key insight: passphrases are easier to remember, so people actually use them without writing them down. For accounts you type manually (WiFi, laptop login), use a passphrase. For accounts managed by a password manager, use random passwords.

Use our Bulk Password Generator — you can generate 5, 10, or 20 passwords at once with one click, then download them as a .txt file. Set it to "No Confusing Characters" mode so new employees don't mix up O/0 or l/I/1 when typing their initial password. For enterprise deployments, consider using the "Easy to Type" mode for temporary passwords that users will change on first login.

When length is limited, maximize character diversity. Use all 4 character types: uppercase (A-Z), lowercase (a-z), numbers (0-9), and every allowed symbol. A 16-character password using all types has 95^16 = 4.4 × 10^31 possible combinations. Use our "Banking Password" mode — it automatically optimizes for these constraints. Also enable 2FA (SMS or authenticator app) as an additional security layer.

API keys and tokens have different requirements than passwords. They're never typed manually, so readability doesn't matter. Use our "Developer / API Key" mode — it generates hex (for shorter keys) or base64 (for longer keys) format tokens. For production API keys, use 32+ characters. Remember: API keys should be stored in environment variables, never committed to git, and rotated regularly.

Using your phone number as WiFi password is terrible — it's easily guessable and only 10 digits. For WiFi, you need 20+ characters because: (1) the password is shared with many people/devices, (2) WPA2 handshakes can be captured and cracked offline, (3) once someone has your WiFi password, they're on your network. Use our "WiFi Password" mode for a strong 20+ character password. If you want something memorable for guests, try our "Pronounceable Password" mode.

No! Even the strongest password becomes worthless if reused. When any one service gets breached (and they do — LinkedIn, Adobe, Yahoo have all been breached), attackers immediately try that email+password combination on every other service. This is called "credential stuffing" and it's automated. Use a unique password for every account. Our Bulk Generator can create multiple unique passwords in seconds. Store them in a password manager.
