Password & Passphrase Generator
Generate a strong random password or a passphrase that is easier to type and remember. Everything happens in your browser. Nothing you generate is sent anywhere.
A genuinely random password, generated locally.
This tool uses your browser's cryptographically secure random number generator (window.crypto) to build a password from the character sets you choose. Nothing is sent to a server. The password is created and stays entirely on your device, in your browser tab.
Common mistakes
Reusing a strong password everywhere. A strong password only helps when it is unique. Generate a new password for every account and store it in a password manager.
Making it memorable by pattern. A word plus a year, a company name plus a symbol, or keyboard walks like qwerty123 are easy for attackers to test.
Making passwords too short. Length usually matters more than complexity. For most business accounts, start at 20 characters when a password manager is available.
Ignoring passphrases. If someone has to type the password manually, a longer passphrase is often better than a shorter complex password.
Password generator FAQ
Is this password generator safe?
Yes. The password is generated locally in your browser using window.crypto. It is not submitted to Define Edge or any other server.
Should I use a password or a passphrase?
Use a random password when you can store it in a password manager. Use a passphrase when someone has to type it manually, such as for Wi-Fi, a shared device, or a temporary setup.
How long should a password be?
For most business accounts, 20 characters is a good default. For Wi-Fi, service accounts, and shared admin credentials, go longer when the system allows it.
Why does this show entropy?
Entropy is an estimate of how much guessing resistance the password has. Higher is better. It is not a guarantee, but it is useful for comparing password strength.
Do strong passwords replace MFA?
No. Use strong unique passwords, a password manager, and MFA. Passwords are only one layer.
