How to Generate a Strong Password

When you generate a password, length matters most. A random password generator that produces 12 characters is already far stronger than an 8-character one, and choosing 15 characters gives even more security. This password generator creates truly random results using cryptographically secure randomness, so there is no pattern an attacker can guess.

Include a mix of uppercase and lowercase letters, numbers, and symbols, and avoid dictionary words and personal details. The strength meter and estimated crack time show the difference each option makes, and because everything runs in your browser you can generate a strong password privately, every time you need one.

Häufig gestellte Fragen (FAQ)

Is my generated password sent to a server?

No, passwords are generated entirely in your browser using cryptographically secure random number generation. Nothing is transmitted or stored.

What makes a password strong?

A strong password is at least 12 characters long, uses uppercase, lowercase, numbers, and symbols, and is unique for each account. Avoid dictionary words and personal information.

What is a password generator?

A password generator is a tool that creates strong, random passwords for you. Instead of relying on predictable, easy-to-guess passwords, it randomly picks characters from uppercase letters, lowercase letters, numbers, and symbols so the result is extremely difficult for attackers to crack.

What is the best password generator?

The best password generator uses cryptographically secure randomness, lets you control password length and character types, generates locally in your browser without sending data to a server, and supports long passwords of 12 to 15 characters or more. Our generator meets all of these criteria and runs entirely on your device for maximum privacy.

How do I make a password generator?

To build your own, start with a cryptographically secure random source, define the character sets you want (lowercase, uppercase, numbers, symbols), choose a password length, then pick characters at random until you reach that length. Requiring at least one character from each set makes the result stronger.

How do I make a password generator in Python?

In Python, use the built-in secrets module, which is designed for cryptographically secure randomness — not the random module. A simple example is: import secrets, string, then use "pwd = ''.join(secrets.choice(string.ascii_letters + string.digits + string.punctuation) for _ in range(12))" to generate a 12-character strong password.

Where can I find the Nexcess password generator?

The Nexcess password generator is built into the Nexcess client area (their hosting control panel) and is available to their customers. If you do not have a Nexcess account, you can use our free password generator here, which creates equally strong random passwords for any account.
