How to generate a random password and store it safely
Combine length and character variety, understand the strength indicator and avoid reusing the output across services.
The generator runs in your browser and uses the device Web Crypto API as its random source. You can select a length from 4 to 128 characters and enable uppercase, lowercase, numbers and symbols. Generation does not require sending the password to the server.
The displayed meter is an estimate based on length and character sets; it does not check breaches, context or reuse. A long, unique password stored in a manager is generally more useful than a hard-to-type string that ends up reused.
What result to expect
You will receive a new string that can be copied directly into a password manager or the destination service.
