What makes a strong password?
Longer passwords generally offer more resistance to guessing than shorter ones. Using a variety of character types can help when a service supports and enforces that variety. Avoiding password reuse and choosing a unique password for each important account further reduces your exposure if one service is compromised.
A password manager can help you store and organize unique credentials without needing to remember each one yourself.
How does secure password generation work?
This generator uses the browser's Web Crypto API to produce secure random values, which are used to select characters from the character groups you enable. Generation happens entirely in your browser. The password is generated in your browser by this tool and is not sent to a GenHub backend for generation.
Why use a unique password for every account?
If you reuse the same password across multiple accounts, a breach at one service can expose your other accounts as well. Using a unique password for each account limits the impact of any single leak.
Security tip: Save important passwords in a reputable password manager and enable multi-factor authentication when available.
Frequently asked questions
How long should my password be?
Longer, unique passwords are generally stronger, but exact requirements vary by service. This generator supports lengths from 4 to 128 characters, so you can match the requirements of the account you are creating a password for.
Are generated passwords random?
Yes. This generator uses the browser Web Crypto API to produce secure random values when selecting characters.
Can I exclude confusing characters?
Yes. Enabling Exclude similar characters removes 0, O, o, 1, l, and I from the character pool.
Does GenHub store my generated password?
This generator does not send generated passwords to a GenHub backend for storage. As with any website, review the site's privacy policy and your browser environment when handling sensitive information.
Should I reuse the same password?
No. It is best to use a unique password for each important account so that a breach on one service does not put your other accounts at risk.
