All generation happens client-side via Web Crypto API. Times measured on average hardware. No server round-trips or rate limits.

Your Generation Pool

The character pool determines how many possible combinations exist for each password. More character types means exponentially more combinations and higher entropy.

Lowercase a-z (26 chars)

The baseline character set. 26 letters provide 4.7 bits of entropy per character. A 16-char lowercase password has ~75 bits of entropy — decent but not ideal.

+ Uppercase A-Z (52 chars)

Adding uppercase doubles the pool. Each character now provides 5.7 bits of entropy. A 16-char mixed-case password has ~91 bits — strong for most uses.

+ Digits 0-9 (62 chars)

Adding numbers bumps the pool to 62 characters and 5.95 bits per character. A 16-char alphanumeric password has ~95 bits of entropy — very strong.

+ Symbols !@#$ (88-95 chars)

The full character set provides 6.5+ bits per character. A 16-char password with all types has ~105 bits of entropy — exceeds most security requirements by a wide margin.

When Do You Need Bulk Passwords?

Employee Onboarding

Provision temporary passwords for new team members across multiple systems. Generate unique passwords for each account, then distribute securely through your password manager.

System Administration

Set up service accounts, database users, API access, and test environments. Each system should have its own unique, strong password.

Event & Workshop Access

Create unique login credentials for attendees. Generate one password per person and distribute via printed cards or secure email.

Account Migration

When migrating users to a new system, generate temporary passwords in bulk. Users can reset them after first login via a secure password reset flow.

Secure Distribution Best Practices

Generating strong passwords is only half the battle — how you distribute them matters equally. Never send passwords in plaintext email, chat messages, or shared documents. Use your organization's password manager sharing feature, encrypted channels, or — best of all — set passwords as temporary and force a reset on first login.

For large batches, export the CSV and import directly into your identity provider (Okta, Azure AD, Google Workspace) or password manager (1Password, Bitwarden). Delete the CSV file immediately after import.

Frequently Asked Questions

Are all passwords unique?

Yes. Each password is generated independently using cryptographic randomness. The probability of two 16-character passwords being identical is astronomically low (less than 1 in 10^28).

Can I export the passwords?

Yes. Use the "Export CSV" button to download all generated passwords as a CSV file. You can import this into spreadsheets or password managers.

How should I distribute bulk passwords?

Never send passwords in plaintext email. Use your organization's password manager sharing feature, encrypted messaging, or force a password reset on first login.

Should I force password changes after distribution?

Yes. Always set initial passwords as temporary and require users to create their own password on first login. This ensures only the end user knows their password.

Is there a limit to how many I can generate?

The UI supports up to 100 passwords per batch. Since generation happens client-side using Web Crypto API, there's no server limit — your browser handles it all in milliseconds.

Are bulk-generated passwords as secure as single ones?

Absolutely. Each password uses the same crypto.getRandomValues() source. Generating in bulk doesn't reduce randomness — every password is independently and cryptographically random.
