How Toqen.app works
Try to steal the login. On the left a password leaves three things behind for an attacker; on the right there is nothing to take. Pull the slider through the stages and run the attacks yourself.

Intelligence does not grant access
An AI can be as clever as you like. If there is nothing to steal, cleverness buys no entry. That is the whole idea: instead of guarding secrets better, stop having secrets that can be carried away.
What's inside
- 1 Try to steal the login · The counters are not decoration. Each one counts the items in that panel that an attacker can carry away.
- 2 Where an ordinary login can be taken apart · It is one secret reused at every step. That is what makes the whole chain only as strong as its weakest link.
- 3 The same chain without a single transferable secret · Nothing in this chain can be replayed: the signature is valid for one challenge and for nothing else.
- 4 Pick an attack and watch what it yields · An honest boundary sits next to the results: a compromised device and a hijacked open session are different problems and need their own answers.
- 5 The key is made inside the chip and stays there · This is the reason there is nothing to intercept: the thing that proves who you are was never on the network in the first place.
- 6 Access is an event, not a permanent property · The countdown is live. What you see is the remaining lifetime of this grant, not an illustration of one.
Explorable Explanations
- Why twenty minutes a day beats one long night A single card, forty-five days of calendar, and the algorithm behind Anki reduced to three buttons. Watch what one well-timed review does to the forgetting curve, what a lapse takes away, and why the whole deck becomes cheap only once the intervals have grown.
- Reading an exam question in a language you are still learning One real question from the Argentine theory bank, taken apart the way a learner actually meets it. Most of the words can be guessed or skipped. The two that cannot are the entire question, and a full translation hands you the answer while hiding which word carried it.
- How much clear road an overtake actually needs You are behind a truck doing seventy, you can see three hundred metres of road, and there is a car coming the other way at the far end of it. The manoeuvre only works if your path and its path fit inside the same stretch. One slider sets your speed; the overlap on screen is exactly how much you are short.
- Who goes first, and why it is almost never the right-hand rule One street, four junctions: an uncontrolled crossroads, a priority road, a green light and a roundabout. The same two cars meet at each of them, and the answer changes three times. The slider drives the route, and the tally at the end counts how often the habit everyone remembers gets it wrong.
- Why stopping has so little to do with the brakes Something blocks the road a hundred metres ahead. Whether you stop in front of it, or reach it and at what speed, comes down to two distances that behave nothing alike: one grows in step with your speed, the other with the square of it. Two sliders, one road.
- How a search engine decides who gets found Ten blue links look like a list. They are the last frame of a pipeline that starts with a crawler and ends with a click curve. One slider walks the whole thing.
- How a generated answer picks the sources it will name An answer engine does not rank pages. It writes a paragraph and then decides which pages to credit for it. One slider follows a single question from fan-out to citation.
- One page, two front doors SEO and GEO are not two projects. They are one document that has to satisfy two different readers: a ranking function and a retrieval step. One slider shows what they share, what they don't, and what it costs to add the second door a year late.
- How a drug is smuggled past the blood–brain barrier The brain refuses almost every drug molecule, and it is right to. One slider follows the trick the labs are trying instead: wrap the molecule in a bubble the wall already knows how to carry.
- How a robot draws the map of a room it has never seen A lidar returns a few hundred dots per sweep and no idea where it is. One slider walks from that cloud to a floor plan with the robot standing in the right spot.
- How two people type in one line without losing a letter Two cursors, one line, nobody holding the pen in the middle. One slider takes an index-based merge apart and rebuilds it out of addresses that sit between the letters.
- Why a quantum computer stops at a lattice Shor’s algorithm eats RSA in one move. The same machine gets almost nothing on a grid of points with a little noise added. One slider shows the difference.
- Cooling a building by pointing it at space A coating that stays colder than the air around it, in full sun, drawing no power at all. One slider follows the heat from the sun to the far side of the atmosphere.
- How a robot predicts the next second A text model guesses the next word. A world model guesses the next frame, mass, speed and gravity included. One slider walks the whole loop, from the camera to the catch.
- Proving a secret without revealing it One slider walks through the stages, the other adds rounds. Watch certainty climb to almost total while the secret stays a secret.
- Getting lithium out of brine: ponds versus direct extraction Move the slider through five stages and compare two ways of taking the same metal out of the same salt water.
- How a personalised mRNA cancer vaccine works Move the slider through five stages and watch how a tumour’s own mutations become the instructions that teach the immune system to find it.
- The edge of the app Everything arriving from outside is untrusted. Break one link at a time and watch where the chain stops and what the screen shows.
- How search over your documents works Move the sliders and watch a search pipeline decide what the model is allowed to see, and what happens when it is fed the wrong passage.
- Retries and slow responses The network drops in the middle of an operation. Press the button twice and see what ends up in the database, with an idempotency key and without one.
- How a language model writes The weights are frozen and nothing is remembered. Pull the sliders and watch the model pick the next piece of text, over and over.
- How a language model learns Pull one slider and watch a pile of random numbers turn into a prediction over a thousand training steps.
- Where electricity comes from Pull one slider and follow the energy from a river all the way to a pump that lifts water back up.
