What Is the Password Generator?
The Password Generator on All Unit Tools is a secure, free online utility that creates strong, random passwords to protect your online accounts and sensitive information. In an era of increasing cyber threats, using weak or reused passwords puts your digital security at serious risk. This tool solves that problem by generating cryptographically secure passwords that are virtually impossible to guess.
Unlike simple password creators, our generator produces truly random passwords using advanced algorithms, ensuring each password is unique and highly secure. Whether you need a password for a new account or want to strengthen existing ones, this tool provides the protection you need in seconds.
Why Strong Passwords Matter
According to cybersecurity experts, weak passwords are involved in over 80% of data breaches. Common passwords like "123456" or "password" can be cracked in milliseconds. Our Password Generator creates passwords that would take centuries to crack, even with advanced computing power.

How to Generate Strong Passwords
Choose Password Length
Select how long your password should be. For maximum security, choose 12-16 characters. For critical accounts, consider 20+ characters.
💡 Minimum 8 characters, recommended 12+, critical 16+
Select Character Types
Choose which character sets to include: uppercase letters, lowercase letters, numbers, and special symbols. Include all four for maximum strength.
Example: A-Z, a-z, 0-9, !@#$%^&*
Configure Options
Set preferences like excluding similar characters (I, l, 1, O, 0) to avoid confusion, or include/exclude specific symbols based on site requirements.
Some sites restrict certain symbols - check requirements first
Generate & Copy
Click "Generate Password" to create your secure password. Use the copy button to instantly copy it to your clipboard for pasting into password fields.
Generate multiple passwords to choose from!
Types of Passwords You Can Generate
🔐 Standard Secure Passwords
Random combinations of letters, numbers, and symbols. Perfect for most online accounts, email, social media, and general web services.
Example: K8#pL3@mN9!qR2$
🔢 PIN Codes & Numeric Passwords
Generate secure numeric-only passwords for banking PINs, phone locks, or systems that require numbers only. Longer than typical 4-6 digit PINs.
Example: 829471536092
🗝️ Memorable Passphrases
Generate passphrases using multiple random words separated by symbols or numbers. Easier to remember while maintaining high security.
Example: correct-horse-battery-staple7!
🏢 Corporate & Admin Passwords
Extra-long, complex passwords for administrative accounts, server access, database credentials, and other high-security business applications.
Example: V#7mP!q9R@2sT5&wZ8*xK3$
📱 App-Specific Passwords
Generate passwords that meet specific application requirements, such as those needing special characters but not others, or fixed-length requirements.
Example: (site-specific requirements)
🌐 Website-Compatible Passwords
Passwords that avoid characters sometimes problematic for websites (like quotes, backslashes, or angle brackets) while maintaining security.
Example: J5$tR8@pL3#kM9!

Password Security Best Practices
✅ Do This
- Use passwords with at least 12 characters
- Include uppercase, lowercase, numbers, and symbols
- Use a unique password for every account
- Store passwords in a secure password manager
- Change passwords after security breaches
❌ Avoid This
- Don't use personal information (names, birthdays)
- Don't reuse passwords across multiple sites
- Avoid dictionary words or common phrases
- Don't write passwords on paper or in unsecured files
- Avoid sequential patterns (12345, abcde)
🔑 Password Manager Tips
Use a reputable password manager to store your generated passwords. Enable two-factor authentication on both your password manager and important accounts. Regularly audit your passwords for weaknesses or breaches using security check tools.
Frequently Asked Questions
Are the passwords really generated securely?
Yes. Our generator uses cryptographically secure random number generation (CSPRNG) algorithms, the same technology used for encryption keys and security tokens. All generation happens locally in your browser—passwords are never transmitted over the internet or stored on our servers.
How long should my password be?
For most accounts, 12-16 characters is recommended. For email, banking, and other critical accounts, use 16+ characters. Each additional character exponentially increases security. An 8-character password can be cracked in hours, while a 12-character password could take centuries with current technology.
What if a website has specific password requirements?
Our tool lets you customize character sets to meet specific requirements. You can include or exclude certain symbol types, avoid confusing characters, and adjust length to match website rules. Some sites have limitations (like no special characters)—adjust your settings accordingly.
How do I remember all these complex passwords?
Don't try to remember them! Use a password manager like LastPass, 1Password, or Bitwarden to securely store all your passwords. You only need to remember one master password for your password manager. This also enables you to use unique passwords for every site without memorization burden.
How often should I change my passwords?
Current security recommendations suggest changing passwords only when there's evidence of compromise, not regularly. However, you should always change passwords after a data breach at a service you use. Regular password changes can lead to weaker passwords (like Password1, Password2, etc.).
