Use longer values
Length usually matters more than visual complexity. For important accounts, use at least 16 random characters or a longer passphrase.
Security Tool

Create random passwords and passphrases locally in your browser. Generated values are not sent to Port233 servers, analytics endpoints, or advertising scripts.
Password
Generate a secure value
Estimated entropy: 103 bits. Values are generated locally with the browser Web Crypto API.
Privacy model for this tool
This page intentionally does not load Google AdSense. Passwords and passphrases are sensitive values, so the generator avoids third-party scripts on the page where those values appear.
The generator uses the browser Web Crypto API and keeps generated values in local page memory until you leave the page, regenerate, or copy them.
Practical password guidance
Use unique passwords
Reusing a password lets one compromised service affect other accounts. Generate a separate value for each site and store it in a password manager.
Protect the clipboard
Clipboard contents can be read by apps and browser pages with permission. Use the auto-clear option when copying on shared or managed devices.
