Password Generator Tutorial
Detailed guide, best practices, and FAQ
Use Cases
The password generator is useful for registering new accounts, changing passwords, setting Wi-Fi passwords, generating API keys, database passwords, and more. Use it when you need a high-strength, unique, brute-force-resistant password in milliseconds.
Features
- Adjustable length: 4 to 64 characters
- Character types: upper/lower case, digits, symbols selectable
- Strength indicator: real-time strength display (weak/medium/strong)
- Cryptographic random: uses crypto.getRandomValues CSPRNG
- Exclude similar: optional removal of confusing chars like 0/O/1/l/I
Examples
Example 1: Scenario 1: Generate a 20-character password with all character types for important accounts (email, banking).
Example 2: Scenario 2: Set a Wi-Fi password with "exclude similar characters" enabled so family members don't confuse 0/O.
Example 3: Scenario 3: Generate a 32-character API key with upper/lower case + digits to meet most platform requirements.
Best Practices
- Use at least 12 characters; 20+ for important accounts
- Include all four character types: upper, lower, digits, symbols
- Use a unique password for each account to limit breach impact
- Pair with a password manager (e.g., 1Password, Bitwarden) for storage
FAQ
Are the generated passwords safe? Are they logged?
Very safe. Passwords are generated using the browser's native crypto.getRandomValues CSPRNG. Generation happens entirely locally with no server transmission and no logging.
Why do generated passwords look so complex?
By design. Strong passwords should appear random and patternless to resist dictionary attacks and pattern guessing. Complexity is the point.
What does "strong" mean in the strength indicator?
"Strong" typically means 16+ characters with all four character types (upper, lower, digits, symbols). Such passwords would take millions of years to brute-force with current computing power.
