What Happens to Your Passkeys When You Lose Your Phone?
Losing your phone is never a pleasant experience. Beyond the immediate frustration of being disconnected, a wave of anxieties about your data security washes over you. If you’ve embraced the future of authentication with passkeys, you’re probably wondering: what happens to them when your phone goes missing? The good news is that passkeys are designed with security and recovery in mind. When you lose your phone, your passkeys aren’t necessarily lost forever, but the process of regaining access depends on how you stored and backed them up.
If you’re using an iPhone and have iCloud Keychain enabled, your passkeys are securely synced and backed up. Even if you lose your iPhone, you can recover your passkeys by signing into iCloud on another device (like a new iPhone, iPad, or Mac) using your Apple ID and password. iCloud Keychain employs end-to-end encryption, meaning even Apple can’t access your passkeys.
Similarly, on Android devices, passkeys are typically stored in the Google Password Manager. If you lose your Android phone, your passkeys are backed up and synced with your Google Account. When you sign into a new Android device with the same Google Account, your passkeys will be available.
However, it’s vital to understand that physical access to your lost phone could compromise your accounts if the device isn’t properly secured. Therefore, marking your phone as lost, remotely locking it, and erasing it (if necessary) are crucial steps to protect your data.
Passkeys: A Deep Dive into Security and Recovery
Passkeys represent a paradigm shift in online security, moving away from vulnerable passwords to a more secure and convenient authentication method. However, like any technology, understanding the nuances of how they work, especially in scenarios like losing your phone, is essential.
The core strength of passkeys lies in their cryptographic architecture. Instead of storing your password on a website’s server, a public key is stored, while the corresponding private key resides securely on your device. When you want to log in, your device uses the private key to create a digital signature that proves you own the account. This process eliminates the risk of password leaks from server breaches and phishing attacks.
Furthermore, both Apple and Google have built-in mechanisms for syncing and backing up passkeys. iCloud Keychain and Google Password Manager act as secure vaults, ensuring that your passkeys are not tied to a single device. This redundancy is vital for recovery in case of device loss or damage.
Safeguarding Passkeys: Proactive Measures
While passkeys offer enhanced security, being proactive about their management is still crucial. Here are some steps you can take to minimize the impact of losing your phone:
- Enable Device Security: Always use a strong passcode, PIN, or biometric authentication (fingerprint or facial recognition) to lock your phone. This is your first line of defense against unauthorized access.
- Enable iCloud Keychain or Google Password Manager: Ensure that passkey syncing and backup are enabled in your device settings.
- Familiarize Yourself with Recovery Options: Understand how to remotely lock, locate, and erase your device through iCloud Find My (for iPhones) or Google Find My Device (for Android phones).
- Use a Password Manager (Even with Passkeys): While passkeys may eventually reduce the need for traditional passwords, a password manager can still be valuable for managing other credentials and storing secure notes.
- Keep Your Recovery Information Up-to-Date: Ensure that your recovery email address and phone number associated with your Apple ID or Google Account are accurate.
- Enable Two-Factor Authentication (2FA) for Your Apple ID or Google Account: Even though passkeys are more secure, 2FA provides an extra layer of security for your account itself.
Passkeys and the Future of Authentication
The adoption of passkeys is steadily growing, with major companies like Amazon, Google, and others embracing this new standard. As more websites and apps implement passkey support, the user experience will become even smoother and more secure.
It’s important to stay informed about the latest developments in passkey technology and best practices. As the technology evolves, so will the strategies for managing and securing your passkeys.

Frequently Asked Questions (FAQs) about Passkeys and Lost Phones
Here are some frequently asked questions to further clarify what happens to your passkeys when you lose your phone:
How do I remotely lock my lost iPhone or Android phone?
- iPhone: Use the Find My app on another Apple device or log in to iCloud.com/find on a computer. You can mark your phone as lost, which will lock it with a passcode and display a message on the screen.
- Android: Use the Find My Device feature. Log in to your Google Account on a computer or another Android device. You can lock your device remotely and display a message on the screen.
Can someone access my passkeys if they steal my unlocked phone?
Yes, if your phone is unlocked, someone could potentially access your passkeys. This is why it’s crucial to always lock your phone with a strong passcode, PIN, or biometric authentication.
What if I didn’t enable iCloud Keychain or Google Password Manager before losing my phone?
If you didn’t enable these services, your passkeys are likely stored only on your lost device, making recovery extremely difficult or impossible. This highlights the importance of enabling these services proactively.
How do I transfer my passkeys to a new phone?
- iPhone: When setting up a new iPhone, sign in with your Apple ID. iCloud Keychain will automatically sync your passkeys to the new device.
- Android: Sign in to your Google Account on the new Android device. Google Password Manager will automatically sync your passkeys.
Are passkeys stored on the SIM card?
No, passkeys are not stored on the SIM card. They are stored securely on your device and synced with your iCloud Keychain or Google Password Manager.
Can I use passkeys on a computer if I lose my phone?
Yes, you can use passkeys on a computer if you have another device (like an iPad or another phone) that can authenticate the login. The process typically involves using a QR code that you scan with your other device.
What happens if I forget my Apple ID or Google Account password?
You’ll need to go through the account recovery process provided by Apple or Google. This usually involves verifying your identity through email, phone number, or security questions. Make sure your recovery information is up-to-date.
Are passkeys phishing-resistant?
Yes, passkeys are highly resistant to phishing attacks. Because the private key never leaves your device and the authentication process relies on cryptographic proof of ownership, it’s impossible for a phishing site to steal your passkey.
What if a website doesn’t support passkeys yet?
If a website doesn’t support passkeys, you’ll still need to use a traditional password. This is where a password manager can be helpful for generating and storing strong passwords.
Are passkeys hardware-dependent?
Passkeys rely on the security features of your device, such as the secure enclave on iPhones or the hardware-backed Keystore on Android devices. This hardware dependency enhances the security of passkeys.
Can I delete a passkey from my Google Account or iCloud Keychain?
Yes, you can delete passkeys from your Google Account or iCloud Keychain through the settings on your device or on the web.
Do passkeys require an internet connection to work?
You need an internet connection to initially sync your passkeys to your device. However, once the passkey is stored on your device, you don’t always need an internet connection to use it for authentication, especially when logging in on the same device.
How do I find which accounts have Passkeys enabled?
On an iPhone, go to Settings > Passwords, and browse the list. If a website or app uses a passkey, it will be indicated there. On Android, check in the Google Password Manager.
Are Passkeys the same as Two-Factor Authentication (2FA)?
No. Passkeys are a replacement for passwords, while 2FA is an additional security layer on top of a password. Passkeys are much more secure than either passwords or even passwords with 2FA.
What if my iPhone is lost or stolen and turned off so that I can’t locate it with Find My iPhone?
In that case, you should still report the iPhone as lost or stolen to law enforcement and your mobile carrier. Then, change the password for your Apple ID on another device. This will prevent anyone who finds or steals your iPhone from accessing your iCloud data, including your passkeys.
By understanding how passkeys work and taking proactive steps to secure your devices, you can confidently embrace this new era of passwordless authentication.
