Password Generator
A strong password is long, random, and uses a mix of character types. This tool generates passwords using your browser's cryptographically secure random number generator, with full control over length and character sets.
How to Use This Tool
- Set your desired password length using the slider.
- Choose which character types to include: uppercase, lowercase, numbers and symbols.

- Click Generate Password(s) and copy the result.
Why Use ToolVigo's Password Generator

- Built-in strength estimate based on length and character variety.
Privacy & Security
Passwords are generated entirely in your browser using a cryptographically secure random number generator. Nothing is sent to or stored on ToolVigo's servers.
Frequently Asked Questions
Is this password generator safe to use?
Yes — it uses the Web Crypto API for randomness and runs entirely client-side, so generated passwords are never transmitted anywhere.
How long should my password be?
Security guidance generally recommends at least 12–16 characters with a mix of character types for important accounts; longer is stronger.
Should I reuse the same password across sites?
No — using a unique password per account, ideally stored in a password manager, limits the damage if one site is breached.
