Secure Password Generator
Create a strong password with control over length and character sets. Generated locally in your browser using the Web Crypto API. It is never sent to a server, never logged, and never included in analytics. Strength depends mainly on length and unpredictability — longer, more varied passwords are harder to guess or crack.
How to use this tool
- Choose a password length.
- Select which character sets to include: lowercase, uppercase, digits, symbols.
- Optionally exclude ambiguous characters like l, 1, O and 0.
- Generate, then copy your password with one tap.
Common use cases
- Creating a new account password
- Replacing a weak or reused password
- Generating passwords for a password manager
Never claim passwords are unhackable; encourage unique passwords per account and use of a password manager.
Frequently asked questions
- Is my generated password sent anywhere?
- No. Password generation runs entirely in your browser using the Web Crypto API. Nothing is transmitted to a server, logged, or included in analytics.
- What makes a password strong?
- Length and unpredictability matter most. A longer password using a wide mix of character types is exponentially harder to guess than a short, predictable one — but no password is truly unhackable, so use a unique password per account and consider a password manager.
