Then remove the missing key, enroll and test a replacement, and keep a tested spare somewhere separate. If no alternative works, use the account provider’s official recovery process; buying a new key alone will not restore access.
The most reliable recovery option is the one you set up before the key goes missing. A security key is a physical authenticator; it is not the same thing as a passkey, an authenticator-app code, a backup code, or an account recovery key. Providers offer different combinations of these options.
What to do first if your key is lost
- Open the provider’s official sign-in page or app. Choose a second factor or recovery option that you previously set up. Never follow a sign-in or recovery link from an unsolicited message or search advertisement.
- After you regain access, remove the missing key. Find the account’s security or two-factor authentication settings and revoke the key. If it may have been stolen, remove it promptly.
- Enroll a compatible replacement. Follow the provider’s instructions to add the key to your account, then sign in with it to confirm it works.
- Add and test a separate spare. Keep it somewhere different from your everyday key. Store backup codes independently of the devices and credentials they protect.
A new key cannot authenticate to an account until it has been enrolled. If you cannot sign in to add it, you must first regain access through an existing factor or the provider’s recovery process.
If another key, device, or second factor is available
At the sign-in prompt, select an alternative method you have already configured. Depending on the service, that might be another enrolled key, a trusted device, a verification or backup code, a passkey, or another approved factor. The choices are account-specific: a method that works for one provider may not exist for another.

Google lists verification codes, Google prompts, backup codes, another key, and a previously trusted computer among possible alternatives. Its instructions are to sign in using another second step, remove the lost key, and add a new one. Google’s instructions for signing in after losing a key provide the account-specific steps.
GitHub documents several possible recovery routes, including a recovery code, passkey, another configured key, fallback number, verified device, SSH token, or personal access token in applicable cases. See GitHub’s account recovery guidance for which options apply to your account.
If the key is present but will not work
A failed sign-in does not by itself show that the key is defective. Check the connection and the sign-in method before replacing it:

- Use a port or connection method the key and device both support; try another supported port or compatible device if available.
- If the device and key support NFC, follow the provider’s prompt for where and how to hold the key.
- Follow the sign-in prompt exactly, and check whether the provider specifies browser or operating-system requirements.
- For Apple Account web sign-in, Apple recommends updating the browser or trying another browser if the key cannot be used.
If it still fails, sign in with another enrolled method and consult the key maker’s official troubleshooting information and the account provider’s instructions. Do not assume a credential on a broken key can be repaired or transferred.

Start account recovery through the provider’s official website or app. Give accurate information and keep access to the email address or phone number the provider asks you to use. The process can involve identity checks or a wait, but the timing and outcome depend on the service.
For Google 2-Step Verification, Google says identity confirmation can take 3–5 business days when no other second step is available. That is Google’s guidance for this situation, not a general recovery estimate for other accounts. Google’s recovery instructions explain the applicable process.

Support cannot necessarily override an account’s authentication rules. GitHub says its support team cannot restore access if a user loses their two-factor credentials and all recovery methods; the account may be permanently inaccessible. Apple similarly warns that losing every trusted device and security key when Apple Account Security Keys is enabled can permanently lock the account. These are provider-specific policies, not a universal rule. GitHub’s recovery policy and Apple’s Security Keys guidance describe their respective cases.
How recovery differs by provider
Google consumer accounts
If you can use another second step, sign in with it, remove the lost key, and add a replacement. If you cannot use another factor, begin Google Account recovery. Google’s stated 3–5 business day timeframe applies to confirming identity for 2-Step Verification recovery when another second step is unavailable; it is not a promised completion time. Google Support: Sign in if you lost your security key.

GitHub
Check whether you can use a recovery code, passkey, another configured security key, fallback number, verified device, SSH token, or personal access token, where applicable. GitHub states that support cannot restore access if two-factor credentials and every recovery method are lost, so configure recovery options while you are still signed in.

Apple Account with Security Keys enabled
Apple requires at least two compatible FIDO-certified keys for this feature and allows up to six. If you do not have a key with you, an iPhone or iPad already signed in to the Apple Account can be brought near the new device to help with sign-in. Apple lists YubiKey 5C NFC, YubiKey 5Ci, and FEITIAN ePass K9 NFC as examples; connector support varies by device. Its guidance also calls for a modern browser and recommends updating or changing browsers if a key fails on the web. These requirements and examples apply to Apple Account Security Keys, not every service. Apple Support: About Security Keys for Apple Account.
Apple’s optional account recovery key is different from a physical security key. It is a 28-character code used with a trusted phone number. Turning it on disables Apple’s standard account-recovery process, and losing it can permanently lock you out; it is not a substitute for a spare hardware key. Apple Support: Set up a recovery key for your Apple Account.
Microsoft accounts
For a personal Microsoft account, a recovery code is a separate credential from a hardware key. It is 25 digits; generating a new one invalidates the previous code. Microsoft advises not to store it on a device you use to sign in. Microsoft Support: How to get a Microsoft account recovery code.

Quick Recap
- Authentication support: Confirm the provider accepts the key and that the model supports the required FIDO function.
- Connector or wireless method: Match USB-C, USB-A, Lightning, or NFC to your devices. An adapter may be needed, but it does not guarantee compatibility.
- Device and browser requirements: Check the provider’s instructions for each operating system, browser, and device you rely on.
- Redundancy: Enroll and test a spare before an emergency, then store it separately from the primary key.
- Other recovery routes: While signed in, confirm that backup codes, trusted devices, fallback factors, or recovery contact details are available and current.
