16 Character Password Generator
Generate random 16-character passwords for your most important accounts.
Your password
Password Security Tips
- Longer passwords are exponentially more secure
- Use a unique password for each account
- Use a password manager to store your passwords safely
Why 16 characters?
A random 16-character password made of uppercase and lowercase letters, digits and symbols has more than 100 bits of entropy. That is strong enough for the accounts that protect everything else: your email, your bank and the master password of your password manager.
Each character is chosen at random with your browser's cryptographic random number generator (Web Crypto API), so there are no patterns to exploit, and the password never leaves your device. Generate up to 100 passwords at once if you need several, and copy or download them.
If a website does not accept some symbols, turn symbols off or exclude specific characters; with 16 characters the password stays strong even with letters and numbers only.
Frequently asked questions
Is a 16-character password hard to crack?
A truly random one is. With all character types it has more than 10^31 possible combinations.
Can I make it without symbols?
Yes. Untick symbols; a random 16-character password of letters and numbers still has about 95 bits of entropy.
Is it safe to generate passwords online here?
The password is generated in your browser and is not transmitted to our server.

What is a Strong Password Generator?
A strong password generator is a security tool that creates random, complex passwords to protect your online accounts from unauthorized access. This secure password generator uses cryptographic algorithms to produce unique combinations of uppercase letters, lowercase letters, numbers, and special symbols that are virtually impossible to guess or crack. Whether you need a single strong password for banking, multiple passwords for social media accounts, or secure passphrases for WiFi networks, this random password generator ensures your digital security with passwords that meet modern security standards.
The generator works by utilizing mathematical entropy to create truly random character sequences that don't follow predictable patterns. You can customize password length from 8 to 128 characters, select which character types to include, exclude ambiguous characters like O and 0, and generate multiple passwords simultaneously. This flexibility makes it perfect for IT professionals managing numerous accounts, individuals prioritizing online security, or businesses implementing password policies. Unlike weak passwords like birthdays or common words, these generated passwords resist brute force attacks and dictionary attacks that hackers commonly use.
Cybersecurity experts recommend using a password generator because 81% of data breaches involve weak or reused passwords. Password managers like LastPass, 1Password, and Bitwarden integrate similar generators, but standalone tools offer privacy advantages since everything happens locally in your browser without transmitting data over the internet. System administrators use them for creating initial employee credentials, developers need them for API keys and tokens, and regular users benefit when setting up new accounts or updating compromised passwords. The tool eliminates human bias that leads to predictable patterns, creating genuinely random passwords that significantly enhance account security.
This free password generator offers advantages over manual password creation or simple patterns. It generates cryptographically secure passwords instantly, prevents the reuse of passwords across accounts, creates combinations impossible to guess through social engineering, and supports various password policies including corporate security requirements. Whether you need a memorable passphrase combining random words, a complex 32-character password for cryptocurrency wallets, or simple 12-character passwords for everyday accounts, this password creator provides reliable security every time without storing or transmitting your generated passwords.
