About this tool
Secure password generator without uploading
Choose length, character types and quantity. Passwords are generated with a browser cryptographic random-number generator and are not stored by the website.
Before you start
Store new passwords in a trusted password manager. Do not reuse the same password across important accounts.
Do I need an account or a paid plan?
No. The current version is free, has no registration and runs on devices with a compatible modern browser.
How are the random passwords created?
NowConverter uses the browser’s cryptographic random-number generator. You can choose password length, character types and quantity.
Randomness and uniqueness matter more than clever-looking patterns
A strong password should be difficult to guess and, just as importantly, unique to one account. Reusing a long password across multiple sites means one breach can expose every account that shares it. A password manager is usually the easiest way to store separate random passwords without memorising each one.
Some services impose length or character restrictions, so generate a value that the destination accepts without manually simplifying it into a predictable pattern. For accounts that support passkeys or multi-factor authentication, those controls can add protection beyond the password itself.
Practical checks
- Use a different generated password for every important account.
- Store passwords in a reputable password manager rather than a plain text file.
- Enable multi-factor authentication where the service supports it.
Practical walkthrough · password generator
Create a unique password for a new account
Example task: You need a password for a service that accepts at least 16 characters and symbols.
Try this workflow
- Choose a long password length and the character sets accepted by the destination.
- Generate a password and store it directly in a password manager.
- Use it only for this account and enable multi-factor authentication if offered.
What to expect
The generator uses cryptographically secure randomness supplied by the browser rather than a memorable human-made pattern.
When to take extra care
Some sites reject particular symbols or long strings. Changing an output manually can reduce its unpredictability; regenerate to meet the rule.
