Are Passkeys Better Than Passwords?

For most people and most personal accounts, yes. Passkeys are generally safer than passwords because they resist phishing and cannot be reused across sites, but they still depend on secure devices, credential managers, and recovery processes.

Why People Are Asking

Passwords have protected online accounts for decades. They have also become one of the weakest parts of everyday security.

Many people reuse passwords across accounts. Some choose passwords that are easy to guess. Others type strong passwords into fake websites without realizing it. Even a careful user can be exposed if a company suffers a data breach and attackers steal password data.

Passkeys are meant to solve some of these problems. Instead of asking you to remember and type a password, a passkey lets your device or credential manager prove it is you, usually after you unlock the device with a fingerprint, face check, PIN, or passcode.

The UK National Cyber Security Centre describes passkeys as a more secure alternative to passwords that are created and managed by software on trusted devices. The NCSC recommends using passkeys over passwords where they are available.[^1]

What We Found

Passkeys Are Much Stronger Against Phishing

The strongest argument for passkeys is that they are phishing-resistant.

A phishing attack usually works by tricking someone into entering a password on a fake website. Once the attacker has the password, they can try to use it on the real site.

Passkeys work differently. There is no password for the user to type, copy, or accidentally give away. The passkey is tied to the real website or app through cryptographic checks. In plain English, that means a fake website cannot use your passkey the same way it could use a stolen password.[^4]

The NCSC’s 2026 technical assessment found that FIDO2 credentials, including passkeys, are “as secure or more secure” than traditional multi-factor authentication for individuals across common attacks and across the full life of the credential. The same assessment says FIDO2 credentials are designed with high entropy, per-account uniqueness, and phishing resistance.[^2]

That matters because many older forms of two-step login can still be phished. The U.S. Phishing-Resistant Authenticator Playbook lists SMS or voice one-time codes, time-based one-time codes, email codes, and some push notifications as phishable or replayable methods, while identifying FIDO2 as phishing-resistant.[^3]

Passkeys Reduce the Damage From Website Data Breaches

Passwords are shared secrets. You know the password, and the service stores data related to it. If attackers steal a password database, they may be able to crack weak passwords or try reused passwords on other sites.

Passkeys do not work that way. They use public-key cryptography. The website or app gets a public key, while the private key stays protected by the user’s device or authenticator. The WebAuthn specification describes public-key credentials as created and stored by an authenticator and limited to the website or app origin they were created for. The U.S. playbook similarly explains that phishing-resistant options use public/private key pairs, with the private key stored on the device and the public key shared with websites or other services.[^3][^4]

That means a breach of the website does not expose a reusable password. Attackers may still steal other account data, but they do not get a password they can type into another service.

This is one of the practical advantages of passkeys: they reduce the risk from password reuse, phishing, and breached password databases.[^2][^3][^4]

Passkeys Can Be Easier for Users

Passkeys can also be more convenient.

For many people, signing in with a passkey feels like unlocking a phone or laptop. You may use your fingerprint, face, device PIN, or screen lock to approve use of the passkey. Those unlock methods are not the passkey itself; they are how your device or credential manager checks that you are allowed to use it.

The NCSC explains that passkeys are created, saved, stored, and managed on trusted devices by a credential manager. It also says the credential manager uses the way you unlock your device before allowing a passkey to be used.[^1]

That convenience matters. Security tools only help if people actually use them. A login method that is both stronger and easier has a better chance of becoming normal.

Passkeys Are Not Magic

Passkeys improve the login process. They do not make an account invincible.

They still depend on the security of your device, browser, operating system, and credential manager. If an attacker gains control of the account, devices, or recovery process used to sync or restore your passkeys, risk may remain. The NCSC specifically warns that users need to maintain the security of the device used to authenticate, choose their FIDO2 authenticator carefully, and protect the account and recovery options used for passkey syncing.[^2]

A synced passkey improves convenience, while a single-device passkey or hardware security key may reduce sync-account risk but increases the importance of backups.

Passkeys also do not stop every kind of phishing. They are strong against attacks that try to steal login credentials. They do not stop someone from tricking you into sending money, downloading malware, changing account settings, or approving a fraudulent action after you are already logged in. The U.S. playbook makes this distinction clearly: phishing-resistant authentication protects the authentication process, but it does not prevent phishing that persuades someone to open a malicious file or install malware.[^3]

What passkeys do not protect against: Passkeys protect the sign-in step. They do not stop scams that persuade you to transfer money, approve a transaction, install malware, or change account settings after you are logged in.

That distinction is important. Passkeys protect authentication. They do not protect every decision a person makes online.

Reality Check

The evidence supports a clear conclusion: passkeys are generally better than passwords for most people and most personal accounts.

They are especially useful against phishing, password reuse, stolen passwords, and some of the damage caused by data breaches.

But the evidence does not support the idea that passwords are gone or that passkeys solve all account-security problems.

Passkeys only help where a service supports them. Many websites still require passwords. Some accounts still rely on weaker backup methods such as email reset links, SMS codes, or support-desk recovery. Those recovery paths can become the weak point. The U.S. playbook notes that registration and account recovery remain attack vectors, even when stronger authenticators are used.[^3]

There is also a practical recovery issue. If you lose access to your phone, laptop, or credential manager, you need a secure way to get back into your accounts. A strong login method can still fail users if recovery is confusing or weak.

The realistic conclusion is not “passwords are dead.” It is: use passkeys where they are available, and keep using strong, unique passwords where they are not.

What You Should Do

Use passkeys for important personal accounts when they are offered. That includes email, banking, cloud storage, shopping, and social media. This follows the NCSC’s consumer guidance, which recommends using passkeys over passwords wherever available.[^1]

For work accounts, follow your employer’s security policy. The strongest evidence cited here is focused on personal-use authentication, not every enterprise setup.

Protect the devices and accounts that store your passkeys. Keep your phone, computer, browser, and operating system updated. Use a strong screen lock. Pay special attention to the Apple, Google, Microsoft, or password-manager account that may sync your passkeys across devices.

Before switching an important account to passkey-only login, check whether you have a backup device, recovery code, or trusted recovery method. A secure login method can still fail users if recovery is confusing or weak.

Avoid creating passkeys on shared or untrusted devices unless you understand how the passkey will be stored and removed.

For accounts that do not support passkeys, use a password manager to create long, unique passwords. Turn on two-step verification where available. The NCSC advises users to continue using strong passwords and two-step verification where passkeys are not available.[^1]

Do not delete passwords or recovery options without understanding how account recovery works. Before relying on passkeys alone, make sure you know what would happen if your phone, laptop, or credential manager became unavailable.

Passkeys are a meaningful improvement. They are not a reason to stop thinking about security.
