Web Browsers Killing Passwords: What’s Changing

Passwords are not being killed outright, but major web browsers are actively building the technology to replace them with passkeys, a passwordless login standard that is already live in Chrome, Safari, Edge, and Firefox. You can still use passwords today, but the shift means that for many sites, you will soon be prompted to use a passkey instead of typing a password. This article explains why browsers are pushing this change, how passkeys work, what it means for you, and what to do in the meantime.

Why Browsers Are Pushing Passwordless

Passwords have a fundamental security problem: they are secrets that can be stolen, guessed, or phished. Even with two-factor authentication, a user can be tricked into handing over both the password and the one-time code. The FIDO Alliance, an industry group including Apple, Google, Microsoft, and others, developed the WebAuthn standard to replace passwords with public-key cryptography. Browsers are implementing this standard because it eliminates the shared secret entirely—the server never sees a password, and the user never types one. For the browser makers, this reduces the burden of password management, data breaches, and account recovery, while giving users a faster login experience.

How Passkeys Work

A passkey is a cryptographic key pair stored on your device. When you register for a site, your device generates a private key (kept securely in the device’s hardware, like a TPM or Secure Enclave) and a public key (sent to the site). When you log in, the site sends a challenge, your device signs it with the private key, and the site verifies the signature with the public key. You unlock the private key with your device’s biometric (fingerprint, face) or a PIN. Because the private key never leaves your device, a phishing site cannot trick you into revealing it—the signature is tied to the site’s domain, so a fake site will not receive a valid signature.

Current Browser Support and Availability

As of 2025, passkeys are supported in all major browsers:

• Chrome (desktop and Android)
• Safari (macOS and iOS)
• Edge (Windows and macOS)
• Firefox (desktop and Android)

Most sites that support passkeys will offer them as an option during login, often after you have already logged in with a password once. You can then create a passkey for that site. Some sites, like Google and Microsoft accounts, already default to passkeys for new users. However, you can still choose to use a password if you prefer—passkeys are an alternative, not a forced replacement yet.

What Happens to Your Existing Passwords?

Your existing passwords are not automatically deleted. Browsers will continue to store and autofill them, and sites will continue to accept them. The change is gradual: sites add passkey support, and browsers nudge users to switch. If you do not want to use passkeys, you can ignore the prompts and keep using passwords. However, you may notice that some sites make it harder to use a password—for example, by requiring a one-time code sent to your email or phone, which is a less convenient but still secure option. In the long term, passwords may become a fallback rather than the primary method, but there is no announced date for their complete removal.

Passkeys vs. Password Managers

Passkeys are often confused with password managers, but they are different. A password manager stores your passwords (and sometimes passkeys) in an encrypted vault, often in the cloud. Passkeys, on the other hand, are tied to a specific device or a cloud sync service (like iCloud Keychain or Google Password Manager). You can use a password manager to store passkeys, but the passkey itself is still a cryptographic key. The main advantage of passkeys over passwords is that they are immune to phishing and credential stuffing. The main disadvantage is that they are tied to your device—if you lose your device and do not have a backup, you could be locked out. Most passkey implementations now allow syncing across devices through your platform’s password manager, so the risk is lower.

Common Problems and Misconceptions

One common misconception is that passkeys are less secure than passwords. In reality, they are more secure because they do not rely on a secret that can be stolen. Another misconception is that passkeys work only on the device where they were created. With syncing, a passkey created on your phone can be used on your laptop if you are signed into the same account (e.g., iCloud or Google). A real problem is that some sites do not yet support passkeys, so you still need a password for those. Also, if you use a public or shared computer, you cannot use a passkey because the private key is not on that device—you would need to use your phone as a passkey via Bluetooth or a QR code, which some browsers support. Finally, if you clear your browser data or switch to a different browser, your passkeys may not transfer unless you have syncing enabled.

How to Start Using Passkeys Today

If you want to try passkeys, here are the steps:

1. Update your browser to the latest version.
2. Go to a site that supports passkeys (e.g., Google, Microsoft, PayPal, or your bank).
3. Log in with your password as usual.
4. Look for a “Create a passkey” or “Use passkey” option in your account settings or after login.
5. Follow the prompts to register your device’s biometric or PIN.
6. Next time you log in, choose “Use passkey” instead of typing your password.

If you have a password manager that supports passkeys (like 1Password, Bitwarden, or Dashlane), you can store the passkey there instead of relying on your browser’s sync. This gives you more control and portability.

What the Future Holds

Passwords are not disappearing overnight, but the trend is clear. Browsers are making passkeys the default option for new accounts, and many sites are requiring them for sensitive actions like changing your password or making a large transfer. The next step is likely to be the removal of passwords for high-risk accounts, with passwords remaining as a fallback for lower-risk sites. There is also work on “multi-device passkeys” that allow you to use a passkey on a device that does not have the private key, by using your phone as a proximity authenticator. In the meantime, you can continue using passwords, but it is wise to start familiarizing yourself with passkeys so the transition is smooth.

Frequently Asked Questions

Will I be forced to use passkeys?

Not immediately. Browsers and sites are rolling out passkeys as an option, not a requirement. You can usually dismiss the prompt and continue using your password. However, some sites may eventually require passkeys for new accounts or for security-sensitive actions, but that is a site-by-site decision.

What if I lose my device with my passkey?

If you have syncing enabled (e.g., through iCloud or Google), your passkeys are backed up and can be restored on a new device. If you do not have syncing, you will need to use a recovery method provided by the site, such as a recovery code or a one-time password sent to your email. It is essential to set up backup methods when you create a passkey.

Are passkeys safer than passwords plus two-factor authentication?

Yes, because passkeys are phishing-resistant. Even if a phishing site tricks you into entering your password and a 2FA code, the passkey signature is tied to the legitimate site’s domain, so the phisher cannot use it. Passkeys also eliminate the risk of password reuse across sites.

Can I use a passkey on multiple devices?

Yes, if you use a syncing password manager or your platform’s sync (iCloud, Google, Microsoft). Without sync, a passkey is tied to one device, but you can create multiple passkeys for the same site (one per device) if the site allows it.

Do passkeys work with password managers?

Yes, most modern password managers (1Password, Bitwarden, Dashlane, and the built-in ones in Chrome, Safari, and Edge) support passkeys. You can store and use passkeys through them, and they often provide cross-platform support.

What happens to my passwords if I switch browsers?

Your passwords are stored in your browser’s password manager or your external password manager. If you switch browsers, you can export your passwords from the old browser and import them into the new one, or use an external password manager that works across browsers. Passkeys may not transfer automatically unless they are synced to the same account.
