Generate strong, random passwords with custom length and character options. Uses cryptographic randomness — nothing is sent to any server.
Set a length from 8 to 64 characters and choose which character types to include: uppercase letters, lowercase letters, numbers, and symbols. Passwords are generated using the browser's cryptographic random number generator — far more secure than Math.random(). Copy the result with one click.
Adjust the length slider and tick the character types you want. A password generates automatically and updates with every change. Click the Regenerate button to get a new one, or Copy to send it to your clipboard.
Most weak passwords are not weak because people do not care about security. They are weak because people are bad at producing high-entropy strings on demand and then are tempted to reuse familiar patterns across accounts.
That is why a password generator matters. It replaces memory-based invention with randomness and turns “make something strong” into a repeatable process instead of a guess.
Humans naturally drift toward names, patterns, substitutions, and memorable fragments. A generator breaks that habit.
Some sites allow long passwords and symbols; others impose awkward rules. A configurable generator lets you stay strong within those constraints.
When changing old or reused passwords, speed matters. The easier it is to generate a new strong one, the less likely you are to fall back to another predictable compromise.
The biggest risk is often not one bad password but the same decent-ish password showing up across multiple important services.
Adding a number or symbol to a familiar word feels stronger than it really is. Random generation avoids that false confidence.
People often keep passwords short because they expect to type them. That trade-off changes once a password manager is part of the workflow.
The best time to create a strong unique password is at the start, before a weak default habit forms.
A generator makes it easier to rotate out old passwords one by one without inventing each replacement.
Support, admin, or testing workflows sometimes need a short-lived credential that should still be difficult to guess.
This tool generates strong passwords. It does not store them, sync them, audit existing accounts, or tell you whether a website handles credentials safely. It is one important piece of account security, not the whole system.
Strong generation works best when paired with unique-per-account use and proper storage in a password manager. The generator solves the randomness problem. The rest of the workflow has to solve the memory and reuse problem.
Yes. This tool uses window.crypto.getRandomValues(), which is the same source of randomness used in security-critical applications. It is significantly more secure than Math.random().
No. Passwords are generated locally in your browser and never sent to any server. Once you close the page they are gone.
At least 16 characters with a mix of all four character types is recommended for most accounts. For high-security systems (root passwords, encryption keys), use 32 or more.
This tool runs entirely in your browser. Nothing you type or paste is sent to any server — all processing happens locally on your device.
