Generate strong random passwords directly in your browser.
Preparing the editor...
The guide and instructions on this page are available while the tool loads.
Password Generator helps users create strong random passwords for accounts, apps, websites, and security-focused workflows.
It supports common password rules such as uppercase letters, lowercase letters, numbers, symbols, and custom length settings.
The goal is to make password creation simple while encouraging stronger security habits such as longer passwords and more character variety.
Typical tasks this tool is built for.
Inputs are processed in the browser for a faster workflow.
Practical tips before you download or share the output.
For best security, use long passwords and store them in a trusted password manager.
Longer reads that pair well with this tool.

Security guide
Use DevToolKit's browser-based generator to create a password, passphrase, or PIN, review its settings, and transfer the result deliberately.
Common next steps after using this tool.
Automatically format and validate JSON in your browser.
Create QR codes for URLs, plain text, email, phone numbers, and Wi-Fi credentials in your browser.
Encode and decode Base64 text directly in your browser.
Format or minify SQL queries directly in your browser.
Decode JSON Web Tokens directly in your browser.
Generate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes in your browser.
Situations where this workflow saves time.
It calls crypto.getRandomValues to fill a Uint32Array and uses rejection sampling before taking a value modulo the requested range. It does not fall back to Math.random when Web Crypto is unavailable.
Generation stops with the message that secure random generation is unavailable in the browser. The component does not provide a weaker random fallback.
Password mode offers 8 through 64 characters and toggles for lowercase letters, uppercase letters, digits, and symbols. When more than one set is enabled, generation places one random character from each selected set before filling and shuffling the remaining positions.
Exclude similar removes i, l, L, I, |, o, O, and 0 from the active sets. Avoid ambiguous punctuation uses a smaller symbol set: ! @ # $ % ^ & * _ + - =.
Passphrase mode selects 3 through 10 words from the component's built-in word list. You can use a hyphen, space, dot, or underscore separator and optionally capitalize each word, add one digit, or add one symbol.
Yes. Each word is selected independently, and the implementation does not remove a chosen word from the list before selecting the next one.
It creates a numeric value only. The PIN length control ranges from 4 through 12 digits.
The rating uses an estimated number of entropy bits from the selected character pool, passphrase word count and additions, or PIN length. It is an estimate only; it does not test a password against external policy, breach data, or a target service.
Copy password uses the browser clipboard API and can fail if access is unavailable. The current implementation does not include a password, passphrase, or PIN download option.
No. A rating reflects the tool's selected-option entropy estimate. Use settings that meet the destination service's rules, avoid reuse across accounts, and handle any generated credential according to your own security requirements.
