Password Generator: Create Strong, Random Passwords

Use this free password generator to create strong, random passwords for your business accounts, tools and logins. Set the length, pick the character types, and copy the result. The password is generated in your browser and is not stored.

What Makes a Password Strong

Strength comes mostly from length and randomness. A password generator removes the human habits that make passwords guessable: names, dates, keyboard patterns and reused words. A random 16 character password drawn from upper and lowercase letters, numbers and symbols has roughly 105 bits of entropy, which puts it far beyond practical guessing attacks.

Current guidance from the US standards body favors length over forced complexity rules. See the NIST digital identity guidelines (SP 800-63B) for the reasoning, and CISA's advice on using strong passwords.

How to Use the Password Generator

1. Choose a length. Use at least 16 characters for important accounts.
2. Select the character types you want: uppercase, lowercase, numbers and symbols.
3. Generate the password.
4. Copy it and save it straight into a password manager.
5. Generate a new one for each account. Never reuse a password.

Password Length Guide

• 12 characters: acceptable minimum for low-risk accounts.
• 16 characters: a good default for email, banking and business tools.
• 20 or more characters: best for password manager master passwords, admin accounts and anything that guards other accounts.

Some sites cap the length or reject certain symbols. If a site rejects your password, shorten it slightly or remove the symbols, but keep it as long as the site allows.

When to Use a Password Generator

• New business accounts. Create unique credentials for your payment processor, hosting, domain registrar and email.
• Shared tools. Generate separate passwords for each team member instead of sharing one login.
• Replacing weak or reused passwords. Update any account that shares a password with another site.
• Wi-Fi and device setup. Set a strong network key for guests and staff.
• Account recovery. Choose a new password after a breach notice.

Safe Habits After You Generate a Password

• Use a password manager. You cannot memorize dozens of random passwords, and you should not try.
• Turn on two-factor authentication. A strong password plus a second factor stops most account takeovers.
• Never email or text a password. Share it through the manager's sharing feature if you must share it at all.
• Change passwords after a breach, not on a fixed schedule.
• Do not reuse passwords. One breached site should not open every other account.

Common Password Mistakes

• Adding a number or symbol to a word. Swapping "a" for "@" or adding "1" at the end is a pattern that cracking tools try first.
• Reusing one password with small changes. If one site leaks it, attackers try the variations everywhere else.
• Storing passwords in a notes app or spreadsheet without protection.
• Choosing personal details such as pet names, birthdays and addresses, which are easy to find online.

A random result from a password generator avoids all four problems because it contains no pattern for an attacker to guess.
