Strong Password Generator
- Browser-based
- No signup
This strong password generator creates random passwords with uppercase, lowercase, numbers, and symbols. Set length and character sets for banking, email, and work accounts—generated locally in your browser.
Strength comes from length and randomness, not clever patterns. Passphrases or 14+ random characters beat short complex rules.
Use a password manager to store generated passwords—you only need to remember one master secret.
100% Client-Side
Your data never leaves your computer.
How to use this tool
Choose password length and character types, generate, then copy into your password manager. Do not reuse passwords across sites.
Worked example
Example: a 16-character password with upper, lower, numbers, and symbols like `Kp8#mN2$vLq9@xR4` resists brute-force and dictionary attacks far better than `Summer2024!`.
When to use this
- Creating credentials for new accounts.
- Rotating passwords after a breach notification.
- Issuing temporary admin passwords for teammates.
Common examples
- 16-character password with symbols for a new SaaS admin account → copy into a password manager immediately.
- 24-character passphrase-style random string for API key rotation in staging.
- 12-character PIN-free password excluding ambiguous characters for legacy systems.
- 20-character admin password with symbols for staging database root (store in vault).
- 16-character Wi-Fi passphrase without ambiguous O/0 characters for guest network poster.
