Weak passwords are the main cause of hacking and account theft on the internet. A brute force attack can crack a 6-character password in seconds, while a 16-character password with a combination of uppercase, lowercase, numbers, and symbols could take millions of years. Our generator uses the browser's cryptographic API (crypto.getRandomValues) to create truly random and impossible-to-predict passwords.
In addition to using strong passwords, it is essential not to reuse the same password across multiple services. If a website suffers a data breach, attackers will try those credentials on other platforms. The ideal solution is to combine unique randomly generated passwords with a password manager like Bitwarden, 1Password, or KeePass, and enable two-factor authentication (2FA) whenever possible.
This tool generates passwords directly in your browser. No password is sent to external servers or stored outside your device. You can customize the length and character types according to each platform's requirements.
Frequently asked questions
What makes a password secure?
A secure password should be at least 12 characters long and include a mix of uppercase, lowercase, numbers, and special symbols. It should be random and not contain dictionary words, proper names, birth dates, or predictable sequences like "123456" or "qwerty".
How often should I change my passwords?
Current NIST (National Institute of Standards and Technology) recommendations suggest that periodic password changes are not necessary if they are strong and unique. You should only change them if you suspect they have been compromised or if a service reports a data breach.
Is it safe to generate passwords online?
Yes, as long as the tool generates passwords locally in your browser, as NexTools does. Our tool uses the browser's crypto.getRandomValues function and does not transmit any data to external servers. Avoid sites that require registration or send data to a server to generate passwords.
