Password Generator

Generate strong, cryptographically secure random passwords with custom rules.

Password Generator — Generate Strong, Cryptographically Secure Passwords

The Password Generator produces cryptographically random, uncrackable passwords using the browser's native Web Cryptography API (`crypto.getRandomValues`). Customize character length, symbols, numbers, and uppercase/lowercase rules with live password strength entropy ratings.

Password Security Checklist

16+ Character Recommended Length

A 16-character randomized string requires billions of years for modern GPU supercomputers to brute-force.

Exclude Ambiguous Characters

Avoid confusing lookalike characters (such as O vs 0, or l vs 1) for easy manual typing on mobile keypads.

100% Client-Side Cryptography

Passwords are generated in your browser memory and are never transmitted, logged, or cached on any server.

One-Click Clipboard Copy

Copy your newly generated secure password directly into password managers like 1Password, Bitwarden, or Apple Keychain.

How to Generate Strong Passwords

1
Select Password Length
Use the length slider to set your desired character count (16-32 recommended).
2
Configure Character Sets
Toggle uppercase, lowercase, numbers, and special symbols based on your site requirements.
3
Exclude Ambiguous Characters
Check the option to omit lookalike characters like 0/O and 1/l for effortless typing.
4
Copy & Save to Vault
Click Copy to clipboard and store your new password securely in your password manager.

Frequently Asked Questions

Are generated passwords saved or seen by ToolsWallet?

No. Passwords exist only in your browser window and are discarded as soon as you refresh or navigate away.

What is a good password length in 2026?

Security researchers recommend at least 14 to 16 characters for regular websites, and 20+ characters for financial institutions and primary email accounts.

Can I use this for WiFi router passwords and API secret keys?

Yes. The cryptographic entropy generated is suitable for WPA3 WiFi passphrases, JWT secret tokens, and database credentials.

What is password entropy and why does it matter?

Password entropy measures password unpredictability in bits. Passwords with 80+ bits of entropy are virtually impossible for modern GPU clusters to crack through brute-force attacks.
