About

Generates secure passwords with configurable length, character sets, and exclusion rules. Features ambiguous character exclusion (e.g., 1/l/I, 0/O), pronounceable password mode for memorable passwords, PIN mode for numeric-only codes, a 5-level strength meter, batch generation (1-50), generation history with copy, entropy display, and custom character set support.

Weak passwords are the leading cause of account compromises; generating strong, unique passwords is essential for security. Provides a flexible generator that balances security requirements with usability for different contexts (PINs, memorable passwords, maximum-strength keys).

Who should use this tool?

Security-conscious users, system administrators managing user credentials, developers generating test passwords, and anyone needing strong, unique passwords for multiple accounts.

Common use cases

Generate strong, unique passwords for personal online accounts with custom complexity requirements
Create batch passwords for team or organizational account provisioning (1-50 at once)
Generate pronounceable passwords for temporary access credentials that users can remember
Create PIN codes (4-8 digit numeric) for physical access systems or application lock screens
Exclude ambiguous characters when passwords will be handwritten or read aloud over the phone
Generate passwords with specific composition requirements for enterprise compliance policies

How to Use

Set the password length using the slider (8-128 characters; 16+ recommended for strong passwords)

Configure character sets: toggle uppercase, lowercase, digits, and special characters on/off as needed

Enable ambiguous character exclusion to remove similar-looking characters (1/l/I, 0/O, etc.)

Select password generation mode: Random (maximum entropy), Pronounceable (memorable syllables), or PIN (digits only)

Use the strength meter to gauge password quality (Weak through Very Strong across 5 levels); monitor entropy bits displayed

Click "Generate" to create password(s); use the batch count selector (1-50) for multiple passwords; review history with timestamps

Examples

Settings: Length=16, all char sets, no exclusions -> Output: "k9#M2pQ$vL8@nX5" | Strength: Very Strong | Entropy: ~95 bits

Settings: Pronounceable mode, Length=12, lowercase only -> Output: "trobamvongre" | Strength: Weak | Entropy: ~56 bits

Best Practices

Use at least 16 characters with all character sets for a password strength of Very Strong (80+ bits of entropy)
Enable ambiguous character exclusion for passwords that will be communicated verbally or written down
Use pronounceable mode only for temporary passwords that users must type manually, not for permanent credentials
Use the batch generator to create unique passwords for all accounts during an onboarding process
Check the entropy display; 60+ bits is adequate for most purposes, 80+ for sensitive accounts

Common Mistakes

Using pronounceable mode for permanent passwords; they have significantly lower entropy than random passwords
Disabling all special characters and then wondering why the strength meter shows Weak
Generating passwords shorter than 12 characters for any important account or service
Reusing the same generated password across multiple accounts instead of generating unique ones
Not excluding ambiguous characters when passwords will be read over the phone or printed

FAQ

What does the entropy value mean? Entropy (in bits) measures unpredictability; each bit doubles the number of guesses needed. 80 bits is considered secure against brute-force attacks.

Is pronounceable mode really secure? Pronounceable passwords have lower entropy per character but are more memorable. Use them only for temporary or low-security contexts.

Can I exclude specific characters beyond ambiguous ones? Yes, use the custom exclusion field to specify any characters to omit from generation.

Where is the password history stored? History is stored in browser localStorage and can be cleared from the settings panel.
