About the password generator

How the generator works

Choose a length and character sets. The browser creates random bytes with the Web Crypto API and builds the password on your device.

Why the password is generated locally

Local generation removes unnecessary risk: the password does not travel over the network, reach server logs, or pass through backend code.

What password length is safe

For everyday accounts, 16 characters is a reasonable minimum. For finance, admin panels, and critical services, use 20-32 characters and a password manager.

Why exclude look-alike characters

This option removes characters such as O, 0, I, and l. It reduces mistakes when a password must be dictated, retyped, or stored manually.

Why use different password types

Different services have different restrictions. Profiles help choose length and characters for an everyday account, banking, servers, or recovery codes.

Why not send a password to a server

Server-side generation creates another point of trust. A password is safer when the secret appears only in the browser and stays with you.
