Strong Password Tips

Strong Password Tips helps you understand what actually makes a password hard to crack and shows, in real time, which best practices a given password already follows.

Type a password and the tool runs it through a checklist drawn from widely accepted security guidance: is it long enough, does it mix lowercase and uppercase letters, numbers and symbols, does it avoid being a common, easily guessed word, and does it steer clear of long runs of repeated characters? Each tip is shown with a clear pass or fail mark, and a simple strength rating summarises how many of the checks you have met.

Because the advice is laid out item by item, you learn the reasoning rather than just receiving a score — making it a useful teaching aid as well as a quick self-check.

Length matters most, so the tool nudges you toward at least twelve characters, ideally a memorable passphrase rather than a short, cryptic string.

Crucially, this is privacy-first: your password is analysed entirely inside your browser and is never transmitted, logged, or saved anywhere.

You can test ideas freely, even for real accounts, knowing nothing leaves your device.

Use it to sanity-check a new password before you commit to it.
