Passkeys: what it is and why you'll soon stop logging in with a password?

Do you remember all your passwords? And do you have a different one for each account? If not, you're not alone. Most people use the same or easily guessable passwords, putting their digital security at risk.

Modern technology, however, brings a new way to log in more securely and conveniently. Without the need to remember anything. It's called a passkey and relies on biometrics or other verification directly on your device. More and more services are offering this login method as a default, and thus regular passwords are gradually fading into the background.

In this article, we will look at what passkeys are, how they work, where you can encounter them today, and why they will likely soon become the new standard.

What are passkeys and how do they differ from regular passwords?

A passkey is a new way of logging in that solves an old well-known problem: passwords are often weak, frequently reused, and easily forgotten. With passkeys, there's nothing you need to remember. You just need verification via a fingerprint, facial scan, or PIN that you already commonly use, for example, to unlock your phone.

The whole process operates on the principle of two keys. The service (like Google or TikTok) only stores the public one, while the private key remains securely stored on your device and never leaves it. During login, the device and server verify that they belong to each other – without typing a password or transmitting sensitive data over the internet.

Unlike traditional passwords, there is nothing to eavesdrop on or steal from the server. Passkeys are resistant to phishing, leaks, and fake login pages. The whole process is faster, safer, and much more convenient for the regular user.

Passwordless login in practice

Logging in with a passkey looks as simple at first glance as unlocking a phone – and that's exactly where its advantage lies. Instead of entering a password, the web or app asks if you want to use the stored key. Confirmation then happens directly on the device, for example through Face ID, Touch ID, or a PIN.

It starts getting interesting when you log in from a device other than where your passkey is stored. For example, opening a webpage on a computer, but the passkey is in your phone. In that case, you might get a prompt for verification on your mobile, perhaps through Bluetooth or a QR code.

The system is designed to work across platforms and be ready for everyday use. Passkeys can be synchronized through an Apple ID, Google account, or some password managers and used conveniently on other devices as well.

Google, Apple, Microsoft: who already supports passkeys

The biggest technology platforms – Google, Apple, and Microsoft – already support passkeys. For some services, they are even the default option when creating a new account.

Other services that already allow passkeys include TikTok, PayPal, eBay, and Uber. More banks and other applications, where security is absolutely essential, are also joining.

Password managers like 1Password, Dashlane, and Bitwarden play a crucial role in allowing passkeys to be stored, synchronized between devices, and used easily outside the Apple, Google, or Microsoft ecosystems.

Passkeys are quickly becoming a new standard – and if you're not using them yet, it's quite likely that you'll encounter them soon.

How to start using passkeys on your device

Getting started with passkeys is very simple, as most devices already have everything you need. If you're using an iPhone, Mac, Android phone, or Windows computer, just have basic security features like a PIN, Face ID, or Touch ID enabled.

When creating a new account or updating settings for existing services, the application often offers you the option to sign in without a password. Once you confirm it, a login key is saved on your device. It will then automatically be offered for each subsequent login.

You can find the management of stored passkeys directly in the device settings. On Apple devices, they are part of your Apple ID in the "Passwords & Security" section, Android integrates them within Google's Password Manager, and tools like 1Password or Dashlane display them directly in their interfaces alongside regular passwords.

The good news is that if you have backups and synchronization enabled (e.g., iCloud or Google account), you can use passkeys across devices, and thus log into a service on a computer using a phone.

The future of login according to FIDO Alliance

This technology is backed by an initiative by the FIDO Alliance, which brings together tech leaders like Google, Apple, Microsoft, and Amazon. Together, they are promoting a new standard aimed at gradually replacing passwords entirely. The goal is not only higher security but also a login experience that feels natural and convenient for users.

FIDO advocates for passwordless logins across devices and services. Thanks to open standards, passkeys already work between different systems and platforms today, and in the future, this type of login will be available everywhere – from regular websites to banking apps, healthcare, or corporate systems.

Digital security starts with you

The internet is increasingly interconnected with our personal data, finances, and everyday lives. And it's also full of threats that may not be immediately visible. Password leaks, fake login pages, or compromised databases are not unusual today.

Passkey technology brings a new layer of protection. It's stronger than traditional passwords and also easier to use. Instead of entering credentials, verification happens directly on your device, which remains fully under your control.

You might not be using them yet. But the world around you is transitioning to them. And the sooner you get acquainted with them, the better for your digital security.
