Password Generator
Create random passwords with configurable length and character sets.
What does Password Generator do?
Password Generator creates random passwords from configurable character sets, length, and symbol rules.
- Primary use: Password Generator creates random passwords from configurable character sets, length, and symbol rules.
- Key technical fact: Password search space grows exponentially: a 16-character password from 94 printable ASCII characters has far more combinations than an 8-character one.
- Practical check: Validate the result before using it in authentication, signing, checksum, or transport code.

Generate strong random passwords
This password generator creates random passwords from the length and character sets you choose. Use it for password-manager entries, test accounts, throwaway credentials, local demos, and secrets that need unpredictable values.
Longer passwords are usually more valuable than clever patterns: the search space grows exponentially with each added character. For real accounts, generate a unique password per service and store it in a dedicated password manager.
How to use
- Set the desired password length using the slider (4 to 128 characters).
- Choose which character types to include: uppercase, lowercase, numbers, and symbols.
- Click Generate to create a new random password.
- Use Copy to save it to the clipboard, or Download to save it as a text file.
Why use a random password?
Random passwords avoid names, dates, keyboard patterns, reused words, and other predictable choices that attackers try first. A long random password is hard to guess because each character is selected from the allowed character pool.
This generator uses browser cryptographic randomness where available, such as crypto.getRandomValues(). Password generation is different from hashing or encryption: it creates a secret, while a password manager helps store and use that secret safely.
Security notes
Use at least 16 characters for most account passwords, include multiple character types when the target site allows them, and avoid saving generated passwords in plain text files unless that is part of a controlled workflow.
Example
A 16-character password using letters, numbers, and symbols might look like this:
--- Settings --- Length: 16 Uppercase: A-Z Lowercase: a-z Numbers: 0-9 Symbols: !@#$%^&* --- Generated Password --- k7#Qm!2pXr&9LwN4
MCP integration
MCP (Model Context Protocol) lets AI agents and apps discover and run Coding.Tools utilities for repeatable conversions, formatting, hashing, and generation workflows.
MCP tool name: password-generator
MCP endpoint: https://coding.tools/mcp
Call tools/list first. Each tool entry includes inputSchema, outputSchema, and examples so an AI agent or client can build valid arguments without guessing.
For tools/call, read result.content[0].text for the display value and result.structuredContent for machine parsing. Tool-level failures return isError: true; protocol failures return a JSON-RPC error.
Example tools/call request:
curl -s https://coding.tools/mcp \
-H "Content-Type: application/json" \
-H "Accept: application/json" \
-H "MCP-Protocol-Version: 2025-06-18" \
-d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"password-generator","arguments":{"options":{"length":20,"symbols":true}}}}'
Most text and data tools accept an input string plus optional options. Browser-only image tools are listed for discovery and return a web UI link when they need browser image APIs.
