What this tool does
This is a password strength meter: type a password and watch a bar fill up across four levels, from too weak to strong, as you go. It turns the question "is this strong enough?" into something you can see, which makes it easy to adjust a password until the meter is where you want it.
How to use it
Start typing in the box and the meter responds live, filling and changing as your password grows. Add a few more characters and watch it climb. Tick Show Password to see the characters as you work. Nothing needs submitting; the feedback is immediate.
How it works
As you type, the meter checks your password's length and whether it uses lowercase, uppercase, numbers, and symbols, and lights up more of the bar as those add up. It all happens in your browser, so the password is never sent anywhere or stored, and it is safe to create one here. The live feedback makes it a handy tool for building a password and improving it on the spot.
A full bar is not the whole story
The meter is great for one thing in particular: improving a password as you type. Add length, add a missing character type, and you can watch the strength climb in real time, which is a satisfying and useful way to build something solid.
Here is the honest caveat, though. A full meter tells you the password is long and varied, not that it is unpredictable, and those are different things. A password like "Password1!" can light up the whole bar while still being weak, because it follows a pattern that cracking tools try early, and the same goes for dictionary words, keyboard runs, and passwords already exposed in a data breach. So use the meter to get the shape right, then finish the job: make the password unique to this one account, and steer clear of anything obvious or reused. The fastest way to a password that genuinely fills the bar is to let the strong password generator build it, and the password strength checker gives the same read as a breakdown rather than a bar.
Questions people ask
What do the meter levels mean?
They track your password from too weak to strong based on its length and the mix of character types. The more of the bar that fills, the longer and more varied the password is.
If the meter is full, is my password safe?
Not necessarily. A full bar means long and varied, but a predictable password can still fill it while being easy to crack. Pair a full meter with a password that is unique and not one that has been breached.
Is it safe to type my password into the meter?
Yes. Everything runs in your browser, with nothing sent over the internet or saved, so testing a real password is fine.
How do I fill the meter?
Add length first, then make sure you are using a mix of character types. For real strength, also keep it unpredictable, a long random password or a passphrase of several random words does both.
