Password Generator

Password generator — create strong, random, unique passwords in the browser

Reused passwords are the leading cause of account takeovers, and "add a number and an exclamation mark to your pet's name" is not a strategy. This password generator creates cryptographically random passwords at a length and character mix you control — lowercase, uppercase, numbers, and symbols — all generated locally in the browser. Nothing is transmitted, stored, or logged.

A visual strength meter gives immediate feedback as you adjust length and character‑set toggles, so you can see the trade‑off between memorability (shorter, simpler) and security (longer, more complex). A single click copies the password to your clipboard.

Who uses it

• Individual users — create unique passwords for new accounts, replace reused passwords during a security cleanup, and generate temporary credentials for guests.
• IT admins and support teams — generate secure temporary passwords for user onboarding, password resets, and service accounts.
• Developers and DevOps engineers — create strong secrets for environment variables, API keys, database connection strings, and CI/CD pipeline configuration.
• Small‑business owners — set up secure passwords for shared tools, social‑media accounts, and vendor portals.

How to use it well

1. Set the password length. 16+ characters is recommended for important accounts; 12 is a reasonable minimum for everyday use.
2. Toggle the character sets: uppercase (A–Z), lowercase (a–z), numbers (0–9), and symbols (!@#$…). At least three of four sets enabled produces strong entropy.
3. Click "Generate new password" to create a fresh random string. The strength meter updates with each generation.
4. Copy the password and store it in a password manager. Do not save passwords in plain‑text files, email drafts, or chat messages.

Practical tips

• Use a password manager (Bitwarden, 1Password, Apple Passwords, etc.) to store generated passwords — a strong password you cannot find is useless.
• Disable symbols if the target service has restrictions (some sites reject !, @, or #) — a long alphanumeric password without symbols is still strong if it is random and unique.
• Generate a fresh password for every account instead of modifying an old one. "Summer2024!" → "Summer2024!!" is not unique; it is a pattern waiting to be guessed.
• Use 20+ characters for accounts that protect financial data, health records, or administrative access.

Common use cases

• Creating unique passwords for email, banking, social media, and shopping accounts
• Setting temporary credentials for new users, clients, or service accounts during onboarding
• Replacing weak or reused passwords after a security review or data‑breach notification
• Generating secrets for environment variables, API keys, and CI/CD pipeline configuration
• Teaching password‑security basics — randomness, length, uniqueness, and the role of password managers

Privacy and browser‑side processing

Passwords are generated on your device using the browser's cryptographic random‑number generator (crypto.getRandomValues). Nothing is transmitted, stored, or logged. The generated password exists only in your clipboard and whatever password manager you paste it into. For production‑credential workflows, follow your organisation's security policy.

People who use this password generator often also need Password Strength Checker (test how long a password would survive a brute‑force attack), QR Code Generator (share WiFi credentials and links via scannable codes), and Base64 Encoder (encode credentials for Basic Auth headers during API testing). All three run in‑browser.
