What this tool calculates

Evaluate router administrator or Wi-Fi password strength entirely inside your browser. The calculation is designed for practical home and small-office network planning.

Important limitations

Results depend on the values and settings you provide. Verify changes with the router manufacturer, internet provider, or an authorized network administrator before applying them to an important network.

Privacy and responsible use

The password check runs entirely in your browser. RouterNAT does not receive or save the entered password. Never reuse a router administrator password on another account.

How to use this result

Verify important changes against your router manual, ISP documentation, or an authorized network administrator. This utility provides planning guidance and does not connect to, scan, or modify your router.
