Strong Password Generator
Generate strong random passwords. Created locally with your browser’s secure random generator — nothing is sent anywhere.
About this tool
The Strong Password Generator produces random passwords using your browser's cryptographically secure random number generator. You set the length, choose how many to produce at once, and select which character sets to draw from. Nothing crosses the network — the passwords are created locally in the page and are never transmitted to us or stored anywhere.
The problem it addresses is familiar. People asked to invent passwords produce predictable ones and then reuse them, which turns a single breach at one provider into an incident across a dozen systems. Random generation removes the pattern, but only works as part of a wider habit: a unique password per account, stored in a password manager rather than a spreadsheet, with multi-factor authentication enabled wherever it is offered. For help rolling that out across a team, see our cyber security services.
How to use it
Set your options and select Generate. A few points worth knowing:
- Set the length first. Length contributes more to strength than character variety, so favour longer passwords wherever the system allows.
- Leave all four character sets enabled unless the target system rejects symbols, which some legacy applications still do.
- Use the count field to generate several at once when provisioning multiple accounts in one sitting.
- Copy the result straight into your password manager rather than a document, an email or a chat message.
- Do not reuse a generated password across services, and replace it if you have reason to think it has been exposed.
Common questions
Are these passwords sent anywhere?
No. They are generated in your browser using the Web Crypto random number generator and are never transmitted to our servers or logged. Closing the page discards them, so save anything you intend to keep before you navigate away.
How long should a password be?
Longer is better, and length matters more than exotic characters. A practical baseline for most accounts is at least 16 characters of random output, and more for administrative, root or service accounts where the impact of compromise is higher. Follow your organization's policy where one exists.
Do I still need multi-factor authentication if my passwords are strong?
Yes. A strong unique password protects against guessing and against reuse from another breach, but it does not help if the credential is phished or captured by malware. Multi-factor authentication, ideally with an authenticator app or hardware key rather than SMS, covers that gap.
