Security guide
What is a secure password?
A secure password combines length, randomness and character variety. It should not contain personal information, common words or be reused across services.
How long should a password be?
Greater length generally improves resistance to brute-force attacks. Use long, unique passwords for important accounts.
Security tips
Use a different password for every service, keep credentials in a password manager, enable two-factor authentication and change compromised passwords.
How are passwords generated?
This tool uses the browser’s secure cryptographic API, crypto.getRandomValues(), to select characters without predictable algorithms. Passwords are not stored.
Frequently asked questions
Questions about passwords
What password length is recommended?
For most accounts, a long password of 16 characters or more is a good baseline; critical accounts may need more.
Is it safe to use this generator?
Yes. It uses crypto.getRandomValues() in your browser and does not store or send passwords.
Are generated passwords stored?
No. They are shown on the page and remain in your browser while you use it.
Which characters should I include?
Combine uppercase, lowercase, numbers and symbols whenever the service allows them.
Is a long password better than a complex one?
Length is fundamental; a long, random password is usually stronger than a short one with symbols.
What does entropy mean?
It estimates the possible search space. More bits mean more potential combinations, but are not an absolute guarantee.
