- • Use at least 16 characters for better security
- • Include uppercase, lowercase, numbers, and symbols
- • Use a unique password for each account
- • Consider using a password manager
- • Enable two-factor authentication when available

How to Use the Password Generator
- 1
Set your password length
Drag the length slider on the right to set the desired password length. For most accounts use 16+ characters. For critical accounts like email and banking, use 20+.
- 2
Choose character types
Select which character types to include: uppercase letters (A–Z), lowercase letters (a–z), numbers (0–9), and symbols (!@#$%). More types = higher entropy = stronger password.
- 3
Exclude similar characters if needed
Check "Exclude similar characters" to remove visually ambiguous characters like i, l, 1, L, o, 0, O. Useful when you need to type the password manually.
- 4
Check the strength indicator
The strength bar and label (Weak / Medium / Strong / Very Strong) updates with each generation. Aim for "Strong" or "Very Strong" for any account that matters.
- 5
Copy and save to a password manager
Click Copy to copy the password to your clipboard, then immediately paste it into your password manager (Bitwarden, 1Password, Dashlane, etc.). Never store passwords in plain text files.
Why Use a Password Generator?
- ✓True randomness that humans can't replicate.Human-created passwords follow predictable patterns (capital first letter, numbers at the end, common substitutions like @ for a). Generators use cryptographically secure random number generators that are provably unpredictable.
- ✓Instant generation at any length or complexity.Generate a 32-character password with all character types in under a second. Try doing that in your head. Our generator runs entirely in your browser — nothing is sent to any server.
- ✓Real-time strength assessment.The strength indicator evaluates length, character variety, and entropy in real time, giving you immediate feedback on whether your configuration meets security best practices.
Frequently Asked Questions
Is the generated password sent to your servers?
No. Password generation uses the Web Crypto API (window.crypto.getRandomValues) which runs entirely inside your browser. No data is ever transmitted to any server. The password exists only on your device.
How secure is a 16-character random password?
A 16-character password using all character types (uppercase, lowercase, numbers, symbols — approximately 95 characters) has 95^16 ≈ 4.4 × 10^31 possible combinations. At one trillion guesses per second, it would take over 1 billion years to crack by brute force.
Should I use a password manager?
Yes — absolutely. Password managers let you use a unique, long, random password for every account without remembering any of them. Leading options include Bitwarden (free, open source), 1Password, and Dashlane. Your browser's built-in password manager is better than nothing, but a dedicated manager offers better security auditing and cross-device sync.
What is entropy in the context of passwords?
Password entropy measures unpredictability in bits. Each bit of entropy doubles the number of possible values. A 16-character password using 95 characters has log₂(95^16) ≈ 105 bits of entropy. Security experts recommend at least 80 bits of entropy for passwords. Our Strong passwords typically exceed this threshold.
