One of my favorite inventions in recent years is face unlocking. Without needing to lift my fingers and type in the numbers, I can get straight into my phone with just a look. Now there is a new technology designed to replace the password called the "passkey"!

Passkeys turn your phone into something a bit like a wallet, which you can use to store membership cards to all of your apps and services. When you need to log in to a website, you'll just have to tap a button on your phone and your passkey wallet will let you in without any worry.

And how does it keep this wallet safe? By using the same biometric (生物统计) "check your phone uses—a face scan or a fingerprint that cannot easily be forged.

Passkeys won't just save us from having to remember passwords but, perhaps logging in with a passkey will actually be much safer than typing a password. This is because it uses a technology called "public key" cryptography (密码) which is one of the building blocks of the Internet-and is how computers have securely communicated with other computers for so many years. To put it simply, it works a bit like a key, instead of a password.

With a password, the website has to keep a database (数据库) of everyone's passwords to check against when you log in. But with a passkey, when you create your account on a website, it will effectively create a new lock and key. The website will keep the lock,     ★     .

I think it's a really clever idea, and that passkeys are going to make our digital lives even safer. So, next time you're complaining that you can't remember your password, don't worry too much. It won't always be like this!
