Password Generator

When to use?

Use it when you need hard-to-guess passwords — new sign-ups, admin initial passwords, dev/QA test accounts. Adjust length, count, character types, and exclude-ambiguous options.

How to use

• Choose the character set (uppercase, lowercase, numbers, symbols).
• Set the length.
• Press generate for a secure password.
• Copy with the copy button.

Input Explanation

Choose length, count, and character types. The exclude-ambiguous option (O, 0, I, l, 1, |) removes easily confused characters. All generation runs only in the browser.

Calculation Basis

It uses crypto.getRandomValues() for a cryptographically secure random array and picks characters to satisfy the chosen character-set conditions.

Usage Examples

• Generate temporary passwords - Mix upper/lowercase, numbers, and symbols for a hard-to-guess temporary password.
• Prepare test accounts - Generate several passwords at once for dev/QA environments.
• Check password policy - Generate candidates matching a service's length and character-type rules.

Examples

• Length 16, all types → "T7$vPq2#mKx9@Ln4" and similar
• Exclude ambiguous → readable passwords without O·0·o·I·l·1·|
• Count 10 → a batch of temporary passwords for test accounts

Cautions

• Generated output is for reference; test carefully before production use.
• Specific web-standard specs or framework-only syntax may cause compatibility issues with the output.

Guides

Building a strong password

Including upper/lowercase, numbers, and symbols with 12+ characters is generally strong. Longer length resists brute force better.

Password management

Generated passwords are not stored by this tool or browser. Keep them safely in a password manager.

Character set and entropy

At the same length, more character types means more combinations. For passwords people must relay, excluding ambiguous characters reduces input errors.

Use a different password per site

Reusing one password across services puts other accounts at risk if one leaks. Use a long, unique password per important account.

FAQ

Are generated passwords stored on a server?

No. They are generated locally with the browser Web Crypto API.

What is exclude-ambiguous?

It excludes easily confused characters like O, 0, o, I, l, 1, |.

Does each generation differ?

Yes. Each press creates a new random password.

What is a safe length?

At least 12 characters with mixed types is recommended, and using a different password per site is safest.
