In recent years, digital security has evolved significantly—especially with the rise of passkeys. Since their introduction in 2021, major tech companies like Apple, Google, Microsoft, and Amazon have integrated passkey support across their platforms. You may have already seen the option to enable a passkey when creating or updating an account. But should you actually use them? The answer is a clear yes. Passkeys not only simplify login processes but also offer stronger security than traditional passwords.
Below, we’ll explore what passkeys are, how they compare to passwords, and why making the switch enhances your online safety.
What Are Passkeys?
To understand passkeys, it's essential to know how they work. A passkey is built on public-key cryptography and consists of two components: a public key and a private key. The public key is stored by the service or platform where you create your account, while the private key remains securely on your device—such as your smartphone, laptop, or tablet—also known as the authenticator.
When you log in to an account protected by a passkey, the service sends a cryptographic challenge to your device. Your device then uses the private key to sign the response and prove your identity—without ever transmitting the key itself. On your end, all you need to do is confirm your identity using biometrics (like Face ID or fingerprint) or a device PIN.
This entire process eliminates the need to remember or enter passwords manually, offering both convenience and robust security.

Are Passkeys More Secure Than Passwords?
Absolutely. Passkeys offer several security advantages over traditional passwords:
1. Phishing Resistance
One of the biggest threats to password security is phishing—where attackers trick users into entering credentials on fake websites. With passkeys, this risk is nearly eliminated. Since no information needs to be typed, there’s nothing for attackers to steal through deceptive sites. Passkeys are automatically recognized only by legitimate domains, making them inherently phishing-resistant.
2. No User Error
Unlike passwords, which rely heavily on user behavior (e.g., choosing strong, unique combinations), passkeys remove human error from the equation. Users don’t create or manage them manually—meaning no weak passwords, reused credentials, or easily guessable patterns.
3. Built-in Two-Factor Authentication (2FA)
Passkeys inherently support two-factor authentication because they bind your identity to a physical device. To authenticate, you must have both the device (something you have) and biometric or PIN verification (something you are/know). This dual-layer protection makes unauthorized access far more difficult compared to password-only accounts.
However, one challenge remains: cross-device compatibility. If you generate a passkey on a Windows PC and want to log in from an iPhone, synchronization becomes necessary. Without a syncing solution—like a supported password manager—you’d need to carry the original device for authentication.
Key Differences Between Passkeys and Passwords
Let’s break down the fundamental differences that set passkeys apart from traditional passwords.
Passkeys Require No Manual Creation
When setting up a password, users are expected to follow best practices: long length, mixed characters, uniqueness across sites. Remembering dozens of such passwords is impractical without tools.
With passkeys, users don’t create anything. The system generates the cryptographic pair automatically. All you do is approve its creation on your device—and from then on, logging in is fast and frictionless.
Passkeys Are Immune to Phishing Attacks
Phishing attacks often succeed because users unknowingly submit their credentials to malicious sites that mimic real ones. Even cautious users can fall victim.
Passkeys prevent this by design. They only respond to verified domains. Even if you visit a convincing fake site, the passkey won’t activate—making it impossible to “enter” your login details.
Passwords Are More Prone to Data Breaches
Despite recommendations for strong passwords (16+ characters, no reuse, no personal info), many people still use weak or repeated passwords. When a service suffers a data breach, these passwords can be exposed and exploited.
In contrast, even if a company’s server storing public keys is compromised, attackers gain nothing useful. The private key never leaves your device—and without it, the public key is useless.

Limited Website Support for Passkeys
While growing rapidly, passkey adoption isn’t universal yet. Some websites still don’t support them as a login method. However, major platforms—including Apple, Google, PayPal, Amazon, Adobe, and Microsoft—already do.

How to Transition to Passkeys for Better Security
Given their security benefits, switching to passkeys whenever possible is highly recommended. However, since not all websites support them yet, you’ll still need strong passwords for some accounts.
Here’s how to stay protected across all platforms:
- Use strong, unique passwords for accounts that don’t support passkeys.
- Enable multi-factor authentication (MFA) wherever available. MFA adds extra layers—such as time-based codes or biometrics—making unauthorized access much harder.
- Store both passwords and passkeys securely using a trusted password manager that supports both methods.
A modern password manager simplifies this transition by securely storing your credentials and syncing passkeys across devices—offering seamless access while maintaining high security standards.

Frequently Asked Questions (FAQ)
Q: Can I use passkeys on multiple devices?
A: Yes—but only if your passkey is synced through a compatible service like iCloud Keychain, Google Password Manager, or a third-party app that supports cross-device sync.
Q: What happens if I lose my device with my passkey?
A: Most platforms allow backup options (e.g., iCloud or Google Drive). However, losing access without backups may lock you out. Always enable recovery methods during setup.
Q: Do I need internet access to use a passkey?
A: No. The authentication happens locally on your device. Internet is only needed to communicate with the service after verification.
Q: Can someone steal my passkey?
A: Extremely unlikely. The private key stays encrypted on your device and never gets transmitted. Even if intercepted, it cannot be used without physical access and biometric confirmation.
Q: Are passkeys replacing passwords completely?
A: Not yet—but they’re on track to become the standard. As more services adopt FIDO2 standards and improve cross-platform support, passkeys will gradually phase out traditional passwords.
Q: Can I use passkeys with my existing password manager?
A: It depends. Some password managers now support passkey storage and syncing (e.g., Keeper, 1Password). Check your provider’s latest features.
By embracing passkeys today, you’re future-proofing your online identity with stronger, simpler authentication. While passwords aren’t obsolete just yet, the shift toward passwordless login is accelerating—and for good reason.
Start adopting passkeys wherever available, secure your remaining accounts with strong passwords and MFA, and use a reliable manager to keep everything organized. Your digital safety has never been easier—or more secure.
