Secure Password Generator
This tool generates a random password using the browser crypto API when available and makes the character choices visible before producing the result.
Generate a random password in your browser
Choose a length and character groups, then generate a password locally.
Processing mode: browser-only for this tool. The interface does not require a server upload to perform its transformation.
Start with a focused browser tool
This tool generates a random password using the browser crypto API when available and makes the character choices visible before producing the result.
Designed for: People creating unique passwords for accounts, test fixtures, and password-manager entries.
How to use this tool
Choose a length from 8 to 64 characters, select the character groups you need, and press Generate. Copy the result into a password manager rather than reusing it across services.
How the result is produced
The interface uses crypto.getRandomValues when available and selects characters from the enabled groups. The UI reports the selected length and character groups so the output is not a black box.
Test examples
A 20-character password with uppercase, lowercase, numbers, and symbols is a stronger starting point than a short memorable phrase reused across sites. Generate a separate value for every account.
Limitations
This page does not store, transmit, or recover passwords. Browser randomness, device security, and the surrounding account provider still matter. Use a reputable password manager and never paste a generated password into a public issue or chat.
Privacy and processing
Generation happens in the browser. The generated value is not sent to the Nofyi server, but browser history, clipboard contents, extensions, or screenshots can still expose it.
