Random Password Generator
Generate strong, random passwords with your choice of length and character types. Runs entirely in your browser — nothing is stored.
Tips for a strong password
- Use 16+ characters — length is the single biggest factor in password strength.
- Mix uppercase, lowercase, numbers and symbols to increase the character pool.
- Never reuse passwords across different sites.
- Store passwords in a password manager (e.g. Bitwarden, 1Password) rather than writing them down.
- This generator uses the browser's cryptographically secure
crypto.getRandomValues()API.
Why Use a Password Generator?
The most common passwords in the world are still "123456" and "password" — used by hundreds of millions of accounts. Human-created passwords tend to follow predictable patterns: names, dates, favourite teams, keyboard walks. Attackers know this and design their cracking tools around it. A truly random password generator eliminates all human pattern bias by using a cryptographically secure algorithm that no attacker can predict. The result is a password that is both strong and genuinely random — something a human brain cannot reliably produce on its own.
Key Features
- Cryptographically secure: Uses the browser's
crypto.getRandomValues()API — the same standard used by password managers - Adjustable length: Slider from 6 to 64 characters — set the length that matches each site's requirements
- Character type controls: Toggle uppercase, lowercase, numbers, and symbols independently
- Exclude ambiguous characters: Option to avoid 0, O, l, I, 1 that can be misread in certain fonts
- Entropy display: Shows bits of entropy and a strength rating (Weak / Fair / Strong / Very Strong)
- Bulk generation: Generate up to 20 unique passwords at once for batch account creation
Real-Life Use Cases
- Creating a new password for a banking, email, or social media account where security is critical
- Generating a strong API key or service account password for a web application or server
- Producing bulk passwords for a team of new employees being onboarded to company systems
- Replacing reused or weak passwords across multiple accounts during a security audit
- Creating a temporary password to share with a contractor before revoking access
Who Can Use This Tool
Everyone who uses online accounts — which is essentially everyone. It is especially valuable for IT administrators managing user accounts, security-conscious individuals performing regular password rotations, developers generating secrets and keys, and anyone setting up new accounts who wants to start with a strong password rather than something they'll remember easily (and an attacker might guess).
Tips & Best Practices
- Use 16+ characters for general accounts and 20+ for email and banking — length is the single biggest factor in security
- Enable symbols for maximum entropy — even adding symbols to a 12-character password makes it significantly harder to crack
- Never use the same password on two different sites — a breach on one site immediately compromises all others with the same password
- Save generated passwords immediately in a password manager (Bitwarden is free and open-source) — do not write them down
- Enable two-factor authentication (2FA) on top of a strong password for the most important accounts
