Basic security
is a right,
not a privilege.
My mission is to make the digital world safer. That is why the tools on this page are free: use them, share them and, most importantly, protect yourself.
They are not gadgets: they come from years of experience in the field and are designed for anyone, at any technical level. The first two run right here; the others are separate services and an app.
Transparent maths
A password
is measured in bits.
Length and alphabet decide how many guesses it takes. Move the slider: the password is created here, in your browser, and never leaves your device.
This assumes a password generated uniformly at random. One chosen by a person has far less: people are predictable, generators are not.
Browser fingerprint
Every click
leaves a trace.
This terminal shows what your browser tells any website, without asking you. Put together, these details are often enough to recognise you, even without cookies.
Everything is computed here, on your device, and disappears when you close the page. The only thing that reaches the server is your IP address, which it receives with every page you open anyway.

Could scammers send email in your domain's name?

Your passwords on your phone, without the cloud
FileFort Vault, the app I designed, keeps passwords, notes and 2FA codes in an encrypted vault that stays on your phone. It does not even have permission to connect to the internet: not a promise, something you can check in the app's manifest.
- Free, for Android
- Passwords, notes and 2FA codes in one encrypted vault
- Unlocks with fingerprint or face
- Encrypted backup in the folder you choose, checked after every write
- No statistics, no ads, no tracking
Your security starts with a conscious choice. And if you have come this far, you have already made it.
