Secure a Lost Phone
A lost phone isn't just a lost device — it's a key to your email, banking, 2FA, and payments. The first 30 minutes matter. This gives the correct order: locate and lock it, stop the SIM and card access, change the passwords that matter, and decide when to remotely wipe — so a bad day doesn't become account takeover and fraud.
What This Skill Produces
- The ordered checklist — locate/lock via the find-my service, then protect the high-risk stuff, in priority sequence
- SIM & payment protection — contact your carrier to suspend the SIM (stops SMS-2FA hijack) and your bank to protect cards/wallet
- Account priorities — change passwords on email and key accounts the phone can unlock or reset
- The wipe decision — locate-and-lock vs. remote-wipe, and the tradeoffs (recovery vs. data exposure)
- Reporting — police report (for theft/insurance) and carrier notification
- Prevention setup — what to enable now so next time is a shrug, not a crisis
Required Inputs
Ask for these if not provided:
- Lost or stolen — and any sense of where (changes locate vs. wipe)
- Phone type — iPhone/Android (determines the find-my/lock tools)
- What's on it — banking/payment apps, 2FA/authenticator, work data
- Protections it had — passcode, biometrics, encryption, find-my enabled
- Access to another device — to run the find-my and change passwords
Framework: Lock, Cut Access, Decide To Wipe
- Locate and lock immediately. Use the platform's find-my service from another device to lock the phone, show a contact message, and see its location — before anything else.
- Cut the SIM and payment access. Call the carrier to suspend the SIM (prevents SMS-code interception) and your bank to protect cards and mobile wallet.
- Change the keystone passwords. Email first (it resets everything), then banking and primary accounts — especially if the phone held 2FA.
- Decide: locate or wipe. If recovery looks likely and it's well-protected, lock and track; if sensitive data is exposed or recovery is hopeless, remote-wipe (accepting you lose tracking).
- Report and prevent. File a police report for theft/insurance, note the IMEI, and set up strong prevention (passcode, biometrics, find-my, encrypted backups) for the future.
Output Format
Lost/stolen phone: [iPhone/Android] · [lost/stolen] · has [banking/2FA]?
Do now (in order)
- Find-my from another device: lock + message + locate.
- Carrier: suspend the SIM. Bank: protect cards/wallet.
- Change passwords: email → banking → primary accounts (esp. if 2FA was on it).
- Wipe decision: [lock & track if recoverable/protected] vs [remote-wipe if data exposed].
- Report: police (theft/insurance, note IMEI) + carrier.
Set up for next time: passcode + biometrics · find-my on · encrypted backups · 2FA that isn't only this phone.
Quality Checks
Anti-Patterns
- Wiping instantly and losing all chance to locate it (when it was protected/recoverable).
- Forgetting the SIM — leaving SMS 2FA hijackable.
- Ignoring banking/wallet access on the device.
- Not changing passwords when the phone held 2FA.
- Skipping the police report/IMEI needed for insurance.
Example Trigger Phrases
- "My phone was just stolen — what do I do right now?"
- "I lost my iPhone and my banking app is on it."
- "Someone took my Android, help me secure everything."
- "Should I wipe my lost phone or try to find it?"
- "My phone's gone and it had my authenticator app on it."
