Password Generator

Generate cryptographically secure, high-entropy passwords with custom length, character sets, and bulk generation.

Privacy Notice: Local Browser Processing: Passwords are generated 100% locally using your browser’s native cryptographic randomness (window.crypto.getRandomValues). Generated passwords are never transmitted across the network or stored in any database.

About Password Generator

Safeguard your accounts against credential stuffing and brute-force attacks with the Zoviva Password Generator. Utilizing the browser’s native crypto.getRandomValues() cryptographic entropy source, create unpredictable passwords with selectable length (6 to 64 chars), character toggles, ambiguous character exclusion, and a live entropy strength meter.

How to Use Password Generator

  1. 1. Choose password length

    Use the slider to pick your length (16+ characters recommended for strong security).

  2. 2. Select character sets

    Toggle uppercase (A-Z), lowercase (a-z), numbers (0-9), and special symbols (!@#$%^&*).

  3. 3. Exclude ambiguous characters if needed

    Enable "Exclude ambiguous characters" to prevent confusion between 1, l, I, 0, and O.

  4. 4. Copy password or generate bulk batch

    Click Copy to save to your password manager, or use the Bulk tab to generate batches of up to 20 passwords.

Common Use Cases

Securing Primary Email & Cloud Accounts

Create 20+ character master passwords for password managers, Google accounts, and Apple IDs.

Wi-Fi Network & Router Credentials

Generate high-entropy passwords for home and office WPA3 wireless networks.

Database & API Secret Keys

Generate random cryptographic secrets and tokens for software configuration.

Pro Tips for Best Results

  • • Length is the single most effective defense: a 16-character password with mixed characters yields over 100 bits of entropy.
  • • Always store your passwords in a dedicated encrypted password manager rather than plain text notes.

Frequently Asked Questions

Is it safe to generate passwords in a web browser?

Yes. Zoviva uses your browser local window.crypto API. Passwords exist purely in your computer memory and are never transmitted over the internet.

What makes a password strong?

Length and entropy. A password with 16 or more mixed characters creates astronomical combinations that take supercomputers trillions of years to guess.

Can I generate multiple passwords at once?

Yes, switch to the "Bulk Batch Generator" tab to generate and copy up to 20 random passwords simultaneously.

What does "Exclude Ambiguous Characters" do?

It eliminates easily confused characters like uppercase I, lowercase l, number 1, uppercase O, and number 0 for easy transcription.
