Strong Password Generator

Online Password Generator — Create Strong Passwords in a Second

Modern life demands strong passwords. Weak or reused combinations are the main cause of account breaches. Our TextHelper AI password generator creates cryptographically strong passwords that cannot be guessed or brute-forced. Everything runs locally in your browser via Web Crypto API — the password never leaves your device.

Generator features

• Length from 4 to 64 characters
• Uppercase (A-Z), lowercase (a-z), digits (0-9), special characters (!@#$%)
• Exclude similar characters (l, I, 1, O, 0) — avoid confusion
• Unique characters without repeats — extra unpredictability
• Cryptographically secure randomness via Web Crypto API

How to choose optimal password length

Security experts recommend passwords of at least 12 characters. For critical accounts (banks, email, crypto wallets) — 16+ characters. Each additional character makes the password exponentially harder to crack. A 16-character password is practically impossible to break even with the most powerful computers.

Security tips

• Don't reuse passwords across different services — if one is breached, attackers get access to all
• Use a password manager (Bitwarden, 1Password, KeePass) for encrypted storage
• Enable two-factor authentication (2FA) — extra protection even if password is compromised
• Rotate passwords regularly for critical accounts (every 6-12 months)
• Check for breaches via haveibeenpwned.com

Why Web Crypto API is safer

Standard JavaScript Math.random() uses pseudo-random algorithms that can be predicted. Web Crypto API uses a cryptographically secure random number generator — the same used for encryption in modern browsers. This guarantees the password is truly random and cannot be guessed.

Frequently Asked Questions

Are generated passwords stored on the server?
No. Generation happens entirely in your browser. No server requests are made, the password never leaves your device.

Can I generate multiple passwords at once?
Yes. Just click "Generate" as many times as needed — each password will be unique.

What makes a password strong?
A password with 12+ characters containing uppercase, lowercase, digits, and special characters. Our generator creates these by default.

Are crypto wallet passwords supported?
Yes. For seed phrases and keys, use maximum length (64 characters) with all character categories.
