Secure Password Generator
Generate strong, unique passwords using cryptographically secure randomness in your browser.
Password settings
Character types
Approximately 129.2 bits of entropy based on length and character-pool size.
Generated passwords
Configure and generate
Secure passwords generated with your browser's cryptographic random-number generator will appear here.
Account security
Use a unique password for every account
Strong, randomly generated passwords significantly reduce the risk of account compromise caused by password reuse, credential stuffing, and brute-force attacks.
Prefer longer passwords
Password length has the greatest impact on resistance to brute-force attacks. A long random password is generally stronger than a short password with complex substitutions.
Combine with a password manager
Password managers make it practical to use unique, randomly generated passwords for every website and application without having to memorize them.

About Secure Password Generator
Unique random passwords reduce the impact of credential stuffing and password reuse.
This generator uses browser cryptographic randomness and configurable character sets to create passwords locally.
Store generated passwords in a trusted password manager rather than relying on memory or reuse.
What makes a strong password
Randomness and length are more important than predictable substitutions.
- Sufficient length
- Cryptographic randomness
- Unique per account
- No personal patterns
- Secure storage
Character-set options
Choose uppercase, lowercase, digits, symbols, and ambiguity filtering according to the target system's requirements.
Password managers
A password manager makes unique long passwords practical and reduces reuse.
Multi-factor authentication
Strong passwords should be combined with MFA where available, especially for important accounts.
FAQ
Frequently asked questions
How long should a password be?
Use the longest practical random password accepted by the service; 16 characters or more is a common starting point.
Are symbols required?
They increase the available character set, but length and randomness are the main factors.
Should I reuse a strong password?
No. Every account should have a unique password.
What are ambiguous characters?
Characters such as O, 0, l, and 1 can be difficult to distinguish visually.
Should I memorize generated passwords?
A trusted password manager is usually more practical.
Are passwords uploaded?
Generation is intended to occur locally in your browser.
