Human civilisation has always been obsessed with locks and keys. Long before passwords, passcodes, PIN numbers, QR codes, authentication apps, and facial recognition, there were physical keys. Monasteries carefully guarded sacred manuscripts behind locked doors. Important documents were secured in heavy chests reinforced with iron bands and impressive-looking padlocks. Kings, merchants, and abbots all relied on the same principle: if you possessed the key, you gained access. If you lost it, you had a problem. Simple. Elegant. Understandable. Somewhere along the way, we appear to have abandoned this perfectly reasonable arrangement.
When I was growing up, a key was a key. You put it in a lock, turned it, and something happened. There was very little ambiguity involved. Hotels, for example, used to hand guests an actual key. Not a card, not an app, not a QR code, and certainly not a smartphone notification. A proper metal key attached to a gloriously oversized wooden key holder large enough to discourage accidental theft and small enough to double as a defensive weapon.
Behind the reception desk stood rows of little compartments where the keys lived when their owners were absent. There was something reassuring about seeing them hanging there. One glance told you who was in, who was out, and which rooms remained available.
Then came key cards. The first few generations never worked properly. They demagnetised if they spent too much time near a wallet, a mobile phone, a television, a refrigerator, or possibly a strong opinion. Returning to reception because your room key had forgotten who you were became a normal part of travel. We accepted this because it was called progress.
Cars followed a similar journey. Early automobiles required drivers to crank the engine manually from the front of the vehicle. This was less convenient than turning a key but considerably more exciting because it occasionally fought back. Eventually ignition keys appeared and, for decades, this seemed to be the perfect solution. You inserted a key, turned it, and the car started. Millions of drivers successfully mastered this complicated procedure. Naturally, the automotive industry concluded that something had to be done.
I learned to drive a stick shift in an adorable dark blue Volkswagen Beetle. The car had a key, a clutch, a gear stick, and very clear expectations about what was required of the driver. Today, many vehicles unlock themselves when you approach. Others start with buttons. Some communicate with smartphones. A growing number use electronic fobs that spend much of their lives hiding in handbags while the owner frantically searches for them.
I am no longer entirely certain what qualifies as a key. The concept itself appears to be undergoing an identity crisis. The same thing happened to navigation. When I learned to drive, every glove compartment contained at least one folding map that could be unfolded to the size of a dining table and refolded only by someone possessing advanced engineering qualifications. Entire journeys were planned around these maps. Today, a cheerful voice from a GPS calmly announces that I should turn left in three hundred metres.
Occasionally it is wrong. The difference is that I now get lost with much greater confidence. Every technological revolution promised simplicity. Every technological revolution lied. Computers were supposed to reduce paperwork. Printers multiplied. Email was supposed to reduce correspondence. My inbox disagrees. Smartphones were supposed to consolidate our digital lives. Instead, they became portable command centres demanding constant attention.
Then came passwords. At first there were only a few. Then every website needed one. Then every website insisted it be unique. Then every website required a capital letter, a lowercase letter, a number, a symbol, and evidence of good moral character. Then came security questions. Then authentication apps. Then one-time codes. Then two-factor authentication. Then passkeys. Then facial recognition.
I have now reached the stage where proving my identity resembles applying for security clearance at a nuclear facility. Of course, passwords alone are no longer considered sufficient. Modern life now requires a password manager because apparently the average adult is expected to maintain a unique password for approximately the same number of accounts as a small multinational corporation.
The password manager promises to solve this problem by remembering everything on your behalf. Unfortunately, the password manager itself requires a password. A very important password. A password so critical that if you forget it, the password manager can no longer help you remember any of the other passwords.
We have essentially created a vault to store all our keys and then misplaced the key to the vault. This is considered progress. Even that is no longer enough. Today, many websites send verification codes to your phone. Others require an authentication app that generates a six-digit number which expires just before you manage to type it correctly. Some organisations have embraced QR codes with evangelical enthusiasm.
QR codes deserve a category of their own. They appeared quietly and then somehow took over civilisation. Many restaurants no longer provide menus. Instead, you are invited to scan a small square on the table, open a website, enlarge the text, rotate your phone, accept cookies, and navigate a digital menu in order to discover whether the soup of the day contains mushrooms.
I realise this is technically more efficient, but I occasionally miss the radical simplicity of being handed a laminated piece of paper. The same phenomenon has spread everywhere. Museums use QR codes. Public transport uses QR codes. Tourist attractions use QR codes. At this point I half expect to find one attached to a tree explaining how to access the forest.
The moment I realised there was no turning back, however, was at the Vatican. For centuries, worshippers dropped coins and banknotes into collection baskets. It was a ritual so simple that it survived wars, monarchies, revolutions, reformations, and the invention of electricity. Yet even the Vatican has embraced the digital age. Today, one can encounter contactless card readers allowing visitors to contribute with a tap.
Somewhere a medieval monk is staring down from heaven in complete bewilderment. The Church has survived two thousand years, countless theological disputes, schisms, reforms, and political upheavals. It now accepts Visa.
The most impressive part is how quickly society accepts all this. Somewhere in a monastery eight hundred years ago, a monk was responsible for one key. Today I need a smartphone, a password manager, facial recognition, an authentication app, access to my email account, and occasionally a QR scanner just to confirm a dinner reservation.
The monk copied sacred manuscripts by candlelight. I cannot access my grocery loyalty card. Yet, despite all my grumbling, I continue adapting. I learned typewriters. I learned floppy disks, fax machines, email, mobile phones, smartphones, cloud computing, artificial intelligence, and whatever the next revolution will be called. I learned to navigate with maps and then with GPS. I learned that modern cars sometimes refuse to acknowledge the existence of an actual key.
The lesson of the past fifty years seems clear. Technology changes. Humans adapt. Complexity accumulates. If my grandfather lost a key, he visited a locksmith. If I lose my phone, I lose access to half my life.
Medieval travellers feared highway robbers. Modern travellers fear a dead phone battery. Progress comes in many forms. The only constant is that every innovation arrives promising to make life easier and somehow leaves us with one more thing to remember. In my case, that thing is usually another password.
