About password generation

Secure password generation in your browser

The random values are generated in the browser. Opselith does not store the result, and the page does not write the generated password to browser storage. The built-in passphrase source contains 4,096 unique local terms and generation requires an estimated minimum of 60 bits.

When to use it

Use strong random passwords for accounts, test credentials and service workflows where your organization permits manual secret generation. Never paste real credentials into support requests.
