Generate ultra-secure passwords in one click. Customize, copy and protect your accounts instantly.
Every day millions of passwords are leaked on the internet. According to Cybersecurity Ventures, cyberattacks cost over $6 trillion annually. Using weak passwords like "123456" or "password" directly puts your bank accounts, social media, email and entire digital identity at risk.
A secure password is your first line of defense against hackers, brute force attacks and identity theft. Cybercriminals use software that can try billions of combinations per second.
GenerarPassword generates completely random passwords directly in your browser using the cryptographic API crypto.getRandomValues(). Nothing is sent to any server.
The longer, the exponentially harder to hack. We recommend 16+.
Combine uppercase, lowercase, numbers and symbols for maximum security.
Each account must have its own unique password.
Bitwarden, 1Password or KeePass store your passwords encrypted.
A secure password must be random, unique and complex. Experts recommend at least 12 characters with uppercase, lowercase, numbers and symbols. Strength is measured by its entropy, the amount of uncertainty it contains. A 16-character password with all types can have over 100 bits of entropy.
We use the Web Crypto API (crypto.getRandomValues()) to generate cryptographically secure randomness. It's the same standard used by banks and governments. Everything happens 100% in your browser.
Yes, as long as the generator works locally in your browser. GenerarPassword uses the native cryptographic API and sends no data to servers. Verify with F12 → Network that there are no requests when generating.
Minimum 12 characters for basic accounts, 16+ for banking or primary email. According to NIST, length is the most important factor.
No, never. Everything happens in your browser. The history only exists in temporary memory and disappears when you close the tab.
It measures randomness in bits. It's calculated as log2(C^L) where C is the character set size and L is length. A 16-character password with 94 possible characters has ~104 bits. 80+ bits is very secure, 100+ is unbreakable.
Yes. It's impossible to memorize unique passwords for dozens of services. Bitwarden (free), 1Password, KeePass or LastPass encrypt everything under a master password.
NIST says it's not necessary if they're strong and unique. Change them if you suspect hacking, a data breach, or if the current one is weak.
Two-factor authentication: in addition to your password, you need another factor like Google Authenticator, Authy or a YubiKey physical key. Always enable it.
Yes, optimized for Android and iOS. Works on Chrome, Safari, Firefox, Edge. Also works offline once loaded.
