Free Secure Password Generator

Create strong random passwords for accounts, test environments, temporary credentials, and policy checks using browser cryptographic randomness.

How to use this tool

  1. Choose the password length and number of passwords.
  2. Select required character groups such as uppercase, lowercase, numbers, and special characters.
  3. Customize allowed special characters if your system has a password policy.
  4. Generate passwords and copy only the values you need.
  5. Export a batch only when you have a safe place to store it.

Examples

  • Generate temporary passwords for a local lab environment.
  • Create sample credentials for documentation or testing.
  • Test whether a password policy accepts a given character set.

Important concepts

  • Longer passwords usually provide more resistance to guessing.
  • Cryptographic randomness is different from Math.random and is more appropriate for passwords.
  • A passphrase can be easier to remember, while a random password is often better for password managers.
  • Generated passwords should be stored only in a trusted password manager or approved secret store.

Common problems

  • Choosing passwords that are too short for the risk level.
  • Reusing one generated password across multiple accounts.
  • Saving exported password files in unsafe locations.
  • Assuming a generated password removes the need for MFA where MFA is available.

Frequently asked questions

Does this use secure randomness?

Yes. Password generation uses the browser crypto library, which is designed for security-sensitive random values.

Are generated passwords stored?

The tool does not upload or store generated passwords. Copy them into an approved password manager or secret store if you need to keep them.
