Password Generator

Generate secure passwords with customizable options

How to Use This Tool

Set Password Length

Use the slider to choose password length between 4 and 64 characters.

Select Character Types

Choose which character types to include: uppercase, lowercase, numbers, and symbols.

Configure Advanced Options

Enable 'Exclude Ambiguous Characters' to avoid characters that look similar (like i, l, 1).

Generate Password

Click 'Generate New' to create a secure password using cryptographically secure randomization.

Copy and Use

Click 'Copy' to save the password to your clipboard. Recent passwords are stored temporarily.

Pro Tips

•Longer passwords are exponentially more secure - aim for at least 12 characters
•Use a mix of all character types for maximum security
•The strength indicator helps you gauge password security (Strong is recommended)
•Excluding ambiguous characters helps when reading passwords aloud or writing them down
•All passwords are generated using cryptographically secure random values
•Recent passwords are only stored in your browser session and cleared when you leave

Creating Strong, Secure Passwords

In today's digital landscape, password security is paramount for protecting your online accounts and sensitive data. A strong password acts as the first line of defense against unauthorized access, data breaches, and identity theft. This password generator uses cryptographically secure random number generation to create unpredictable passwords that meet modern security standards. Understanding password entropy, character complexity, and length requirements helps you create passwords that can withstand various attack methods including brute force, dictionary attacks, and rainbow tables.

Frequently Asked Questions

How long should a secure password be?

▼

For most accounts, a minimum of 12 characters is recommended, but 16 or more characters provides excellent security. Each additional character exponentially increases the time needed to crack the password. Critical accounts like banking or email should use 20+ characters when possible.

What makes a password strong?

▼

A strong password combines length with complexity. It should include a mix of uppercase letters, lowercase letters, numbers, and symbols. The key is unpredictability - avoid patterns, dictionary words, or personal information. Password strength is measured in bits of entropy, with 60+ bits considered strong.

Should I use the same password for multiple accounts?

▼

Never use the same password for multiple accounts. If one service is compromised, all your accounts become vulnerable. Use this generator to create unique passwords for each account, and consider using a password manager to store them securely.

Why exclude ambiguous characters?

▼

Ambiguous characters like 'i', 'l', '1', 'o', '0', 'O' can be difficult to distinguish, especially when written down or displayed in certain fonts. Excluding them prevents errors when entering passwords manually while maintaining security through increased length.

How often should I change my passwords?

▼

Current security best practices recommend changing passwords only when there's a reason to do so: after a breach, when sharing ends, or if you suspect compromise. Frequent arbitrary changes can lead to weaker passwords or password reuse. Focus on creating strong, unique passwords from the start.
