Secure Password Generator
- Browser-based
- No signup
This secure password generator creates cryptographically strong random passwords for banking, email, and admin accounts. Set length, symbols, and character exclusions—generated locally in your browser with no storage or transmission.
Security comes from length and randomness. Fourteen or more random characters beat short complex patterns.
Use a password manager so you only memorize one master secret.
100% Client-Side
Your data never leaves your computer.
How to use this tool
Choose length and character types, generate, then copy into your password manager. Never reuse across sites.
Worked example
Example: a 20-character secure password with mixed case, numbers, and symbols resists brute force far better than `P@ssw0rd2024`.
When to use this
- Creating credentials for new high-value accounts.
- Rotating passwords after breach notifications.
- 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.
