If you’ve ever forgotten a password, reused one across multiple sites, or worried about getting hacked, you’re not alone. Passwords have been a necessary evil of the internet for decades – but new technology might finally allow them to be replaced: passkeys.
A passkey is a modern, more secure way to sign in to apps and websites without using a traditional password. Instead of something you have to remember, or consult a Password Manager, a passkey uses cryptography and your device to prove who you are.
How Passkeys work
Passkeys are based on public-key cryptography, the same technology used to secure HTTPS websites and online banking. When you create a passkey for a website:
- Your device generates a pair of cryptographic keys.
- The public key is stored on the website’s server.
- The private key stays safely on your device.
When you log in later, your device proves it has the private key without ever sending it over the internet. To unlock the passkey, you use something you already rely on – Face ID, Touch ID, a fingerprint, or a device PIN. No secret ever travels across the network, which is a significant security upgrade.
Are Passkeys more secure than passwords?
Passwords have several built-in weaknesses:
- They can be guessed or cracked – especially simple ones.
- They’re often reused across multiple sites.
- They can be stolen in phishing attacks or data breaches.
Passkeys eliminate these risks almost entirely. They are:
- Unique per website.
- Stored securely on your device.
- Useless to attackers even if a server is breached.
This makes them much harder to be phished or reused. And even if someone tricks you into visiting a fake site, your passkey simply won’t work there.
With passkeys, you don’t have to remember a password or consult a Password Manager. And there’s no annoying reset emails. You just unlock your device the same way you already do. Many passkeys can sync across your devices using secure cloud services, so signing in on a new phone or laptop should be seamless.
Are there downsides to using Passkeys?
Passkeys are not perfect, but the downsides are mostly practical and transitional rather than fundamental flaws:
1. Device dependence
Passkeys live on your devices. That means if you lose your phone or laptop, access can be temporarily tricky. You’re relying on device recovery options (cloud sync, backup devices, account recovery flows). This isn’t usually a deal-breaker, but it does shift responsibility from “remember a password” to “secure your devices properly.”
2. Ecosystem lock-In
Right now, passkeys work best within ecosystems: Apple passkeys work beautifully across Apple devices and Google passkeys work best in the Google ecosystem. Cross-platform support exists, but it can still feel clunky. For people who mix devices (Windows + iPhone + Linux, for example), the experience isn’t smooth yet.
3. Account recovery can be more difficult
With passwords, recovery is familiar: reset email, new password, done. With passkeys, recovery depends on the provider’s process. Losing all devices and cloud access can mean a longer, more manual recovery. Some services haven’t nailed this user experience yet.
4. Limited support (for now)
Not every website or app supports passkeys (yet). Some services offer passkeys as an option, not a replacement, and still require a password as a fallback. We’re still in a transition period where some service providers have confusing or half-finished implementations.
5. Less transparent and harder to understand
Passwords are conceptually simple: “I type a secret.” Passkeys are more abstract: cryptographic keys, device-based authentication, cloud syncing… it’s all starting to sound like jargon. For many users, not knowing what the “key” is or where it lives feels uncomfortable – even if it’s actually safer.
6. Shared and public devices are very tricky
Passkeys are designed for personal devices. Using them on shared computers, public terminals or workstations with multiple users requires extra steps (like temporary sessions). This can be awkward compared to just typing a password.
The bottom line
Passkeys aren’t a future concept – they’re already here. Many companies supporting passkeys include Apple, Google, Microsoft, Amazon and PayPal. They are more secure, usually more convenient than passwords and are harder for attackers to exploit. But they:
- Tie your identity more closely to your devices.
- Depend on ecosystems and recovery systems working well.
- Still suffer from uneven adoption.
Passwords won’t disappear overnight, but passkeys are quickly becoming the new standard. As more websites adopt them, logging in should hopefully feel faster, safer, and far less frustrating.
Passkeys aim to be what passwords were always trying to be – just without the headaches.
