1. Photograph your wallet contents. Lay out every card front-and-back, take a photo, save it to a private cloud folder (not your camera roll). If everything goes missing, you'll have account numbers and customer service numbers.
2. Set up Find My iPhone or Find My Device. If you don't have it on, you can't find your phone. 30 seconds in Settings.
3. Use a strong phone passcode. 6+ digits minimum, alphanumeric is even better. Face ID/Touch ID with a 4-digit PIN is weak.
4. Take your SS card OUT of your wallet. You almost never need it — you do need to know the number. Memorize it, store the card at home in a fireproof spot.
5. Use Apple Pay or Google Pay where you can. Tokenized — your actual card number isn't transmitted. If your phone is stolen and locked, the cards are useless to the thief.
6. Enable 2FA on your email. Email is the master key to everything else (every "forgot password" link goes there). Use an authenticator app, not SMS, if possible.
7. Set up account recovery now — recovery email, recovery phone, backup codes. Try this before you need it.
8. Use a password manager. 1Password, Bitwarden, Apple Keychain, Google Password Manager — pick one. Reusing passwords is the #1 cause of cascading account takeovers.
9. Place a free credit freeze even if nothing has happened. Costs nothing. Lift it temporarily when you need credit. Strongest possible protection.
10. Keep emergency cash somewhere not in your wallet. $40-$100 in your car glove box, in a drawer at home, somewhere. If your wallet vanishes, you're not stranded.
