Losing a phone or security key doesn’t lock you out of your work account. There’s a recovery process.

Step 1: Don’t panic

Your passkey is protected. Even if someone finds your device:

  • Phone passkeys require your fingerprint, face, or device PIN to use. Someone can’t use your passkey without unlocking your phone first.
  • Security keys require a PIN (and optionally a fingerprint). Without the PIN, the key is useless after a few failed attempts.
  • Windows Hello requires your biometric or PIN. A stolen laptop that’s locked can’t be used to sign in.

Your account is not immediately compromised.

Step 2: Sign in from another device (if you can)

If you registered passkeys on more than one device - for example, both your phone and your laptop - use the other device to sign in. This is the fastest way to stay productive.

Step 3: Contact your helpdesk

If you can’t sign in at all, contact your IT helpdesk:

  • By phone - call the number your organization provides (check your employee handbook, intranet, or ask a colleague)
  • In person - visit the IT support desk if you’re in the office
  • By email from a personal device - if your org allows it, email the helpdesk from a personal email address

Tell them:

  • Your name and employee ID
  • What you lost (phone, security key, laptop)
  • Whether you have any other sign-in methods available

Step 4: Verify your identity

Your helpdesk will verify that you are who you say you are before granting access. This might involve:

  • Confirming information only you would know (employee ID, manager name, recent activity)
  • Manager or supervisor approval
  • A video call if you’re remote
  • In-person verification with a photo ID

This step exists to protect you. If someone stole your phone and called the helpdesk pretending to be you, this is what stops them.

Step 5: Get a Temporary Access Pass

Once your identity is verified, your helpdesk will issue a Temporary Access Pass (TAP) - a one-time code with a limited time window (typically a few hours). You’ll use this to:

  1. Sign in to your account from a browser
  2. Go to My Security Info
  3. Register a new passkey on your replacement device or a different device

The TAP expires after use or after the time window closes, whichever comes first.

Step 6: Remove the old passkey

Once you’ve set up a new passkey and confirmed it works:

  1. Go to My Security Info
  2. Find the old passkey in your registered methods (it will still be listed)
  3. Click Delete to remove it

If you can’t remove it yourself, ask your helpdesk to remove the old credential from your account.

Step 7: Secure the lost device

Depending on what you lost:

  • Phone - use your platform’s remote wipe or “Find My” feature (Find My iPhone, Google Find My Device) to lock or erase the device
  • Security key - report it to your IT team so they know it’s compromised. The key’s PIN protects it, but it should still be revoked.
  • Laptop - report it to IT immediately. They can remotely wipe a managed device through Intune.

Prevention tips

  • Register multiple passkeys - set up on both your phone and your computer. Losing one doesn’t lock you out.
  • Keep your security key on a lanyard or keychain - treat it like a physical key
  • Know your helpdesk contact info before you need it - save the number in your personal phone
  • Enable Find My Device on your phone and laptop so you can locate or wipe them remotely

Timeline

Step Typical time
Contact helpdesk Immediate
Identity verification 5-30 minutes (depends on process)
Receive TAP Minutes after verification
Register new passkey 2-3 minutes
Remove old passkey 1 minute
Total recovery Under 1 hour in most cases

The longest part is usually identity verification, especially if you’re remote and can’t verify in person.
