Hardware Security Keys

The single biggest upgrade you can make — a physical key a remote attacker can't touch, phishing-resistant in a way no code-based 2FA is.

  • YubiKey 5C NFC

    YubiKey 5C NFC

    Same key, USB-C — get this one if your laptop and phone are USB-C.

    Why this works: Identical phishing-resistant protection to the 5 NFC: the key checks the site's true address before it signs, so a fake page gets nothing. This is simply the USB-C body for newer laptops and phones.

  • YubiKey 5Ci

    YubiKey 5Ci

    Dual Lightning + USB-C connectors — the hardware key for iPhone users.

    Why this works: Same phishing-resistant FIDO protection as the rest of the 5 Series; the difference is the Lightning connector, which secures logins directly on an iPhone where USB-C and NFC keys get awkward. Note: this is a possession key, not the fingerprint Bio.

  • YubiKey Bio Series

    YubiKey Bio Series

    Adds a fingerprint reader to the key itself, so a stolen key alone is useless.

    Why this works: Your fingerprint is read and matched on the key itself and never leaves it, so there's no secret to phish or intercept. And because the key won't authenticate without your print, a lost or stolen key is dead weight to whoever finds it.

  • Hardware Key Storage Case

    Hardware Key Storage Case

    A hard, portable case so your keys — and their backups — don't rattle around loose or go missing.

    Why this works: Hardware keys are small and easy to lose, and a lost key with no backup is a lockout waiting to happen. A dedicated case keeps your primary and spare keys together and protected, so the 'buy two' rule actually survives daily life.

  • Waterproof Key Capsule

    Waterproof Key Capsule

    A sealed keychain capsule that waterproofs and shock-proofs a spare key or recovery backup.

    Why this works: A backup only helps if it survives. This sealed, shock-absorbing capsule protects a spare hardware key or a written recovery phrase from water, drops, and pocket grit — the quiet failure modes that ruin a backup right when you finally need it.

Privacy & Anti-Surveillance

Cheap, boring, effective — the stuff that closes the gaps snoops actually use.

  • Laptop Webcam Cover Slide

    Laptop Webcam Cover Slide

    A two-dollar piece of plastic that ends camera-access blackmail scams.

    Why this works: Malware can switch a camera on without tripping the indicator light, but software can't see through a physical shutter. Covering the lens removes the footage that 'we recorded you' sextortion scams rely on — there's nothing to capture.

    View on Amazon
  • Webcam Cover Stickers

    Webcam Cover Stickers

    Restickable dots for every camera you can't slide a cover over — phone, tablet, smart TV.

    Why this works: Not every device takes a sliding shutter. Low-tack restickable dots block the lens on phones, tablets, and laptops without leaving residue, so the 'we recorded you through your camera' sextortion bluff has nothing to show.

  • Laptop Privacy Screen Filter

    Laptop Privacy Screen Filter

    Stops shoulder-surfing in cafes, planes, and offices — comes in sizes to match your screen.

    Why this works: A micro-louver film collapses the screen's viewing angle so anything off-center reads as black. In public, that blocks the casual shoulder-surfer from reading the password or one-time code you're typing in plain sight.

  • USB Data Blocker

    USB Data Blocker

    Charge at any public USB port without risking your data — power flows, data can't.

    Why this works: Public USB ports can carry data as well as power, and a tampered one can pull files off your phone or push malware — an attack called juice jacking. A data blocker physically disconnects the data pins so only current passes, making any airport, hotel, or cafe port safe to plug into.

  • GL-iNet Travel Router (GL-SFT1200)

    GL-iNet Travel Router (GL-SFT1200)

    Your own private, encrypted Wi-Fi layer on top of sketchy hotel and airport networks.

    Why this works: Public Wi-Fi is a classic spot for snooping and fake 'evil-twin' hotspots. A travel router connects to the hotel network once, then gives your devices their own protected network with built-in VPN support — so your traffic is encrypted and isolated from everyone else on that connection.

RFID & Signal Blocking

Contactless cards, key fobs, and passports all answer any reader that powers them — and keyless-car thieves go further, relaying your key's signal to drive off. These shield that signal across every form factor, from a single wallet card to a full Faraday bag. Pick what fits how you carry.

  • Men's RFID-Blocking Wallet

    Men's RFID-Blocking Wallet

    Leather bifold with an ID window — same skim-proofing, classic shape.

    Why this works: Contactless cards and IDs answer any reader that powers them over radio — including a skimmer in someone's bag. The wallet's shielding layer acts as a Faraday cage and blocks that signal, so the chip never wakes up to be read in the first place.

    View on Amazon
  • Women's RFID-Blocking Wallet

    Women's RFID-Blocking Wallet

    A compact genuine-leather wallet in several colors.

    Why this works: Same Faraday-shielding principle as any RFID wallet: it blocks the radio signal a skimmer uses to power and read your cards through a bag or pocket. This one just trades the bifold for a compact design and comes in multiple colors.

    View on Amazon
  • Women's RFID Wallet (Cream)

    Women's RFID Wallet (Cream)

    A slim cream bifold with a zip pocket — RFID-shielded like the rest.

    Why this works: Same Faraday shielding that stops a skimmer from powering and reading your cards through a bag, in a lighter cream colorway with a zippered coin pocket. Choose it over the other women's wallet purely on style.

  • Women's RFID Wallet with AirTag Holder

    Women's RFID Wallet with AirTag Holder

    RFID shielding plus a built-in slot to track it if it's lost or lifted.

    Why this works: Two layers in one: the shielding stops cards being skimmed, and a dedicated pocket holds an Apple AirTag so a lost or stolen wallet can be located. (The AirTag itself is sold separately.)

  • RFID-Blocking Crossbody Bag

    RFID-Blocking Crossbody Bag

    An RFID-lined bag that shields whatever you drop in — no separate wallet needed.

    Why this works: The lining blocks contactless reads of any card, fob, or passport inside, which is handy in crowded transit and travel where bump-skimming is easiest. A good fit if you'd rather protect the whole bag than carry a shielded wallet.

    View on Amazon
  • RFID-Blocking Passport Sleeves

    RFID-Blocking Passport Sleeves

    Shields the chip in your passport from being read at a distance.

    Why this works: Modern passports carry an RFID chip holding your identity data. A shielding sleeve stops it being read from across a terminal or hotel lobby — cheap insurance for the one document you really don't want cloned while traveling.

    View on Amazon
  • RFID-Blocking Cards (4-Pack)

    RFID-Blocking Cards (4-Pack)

    Turn any wallet RFID-safe — slim cards you just tuck in beside your own.

    Why this works: Each card acts as a shield that jams the radio field a skimmer relies on, protecting the cards next to it without replacing your wallet. The cheapest way to RFID-proof a wallet, bag, or pouch you already own.

  • Faraday Key Fob Pouch

    Faraday Key Fob Pouch

    Blocks key-fob relay attacks — the trick used to steal keyless cars from the driveway.

    Why this works: Keyless cars get stolen by 'relay' attacks: thieves capture and amplify your fob's signal from inside your house to unlock and start the car outside. A Faraday pouch blocks the fob's signal entirely, so there's nothing to relay — drop your keys in and the car is unreachable.

    View on Amazon
  • Fireproof Faraday Bag

    Fireproof Faraday Bag

    Fully shields a phone, fob, or documents — fireproof and water-resistant too.

    Why this works: A fully shielded bag cuts all signal to whatever's inside — useful for isolating a phone you suspect is compromised, or storing spare fobs and devices. This one adds fireproof, water-resistant layers, so it doubles as safe storage for passports and documents.

Fraud Prevention at Home

Identity theft still loves paper. Close that door too.

  • Amazon Basics 12-Sheet Cross-Cut Shredder

    Amazon Basics 12-Sheet Cross-Cut Shredder

    Higher-capacity cross-cut — for regular shredding, not just the occasional envelope.

    Why this works: Same cross-cut protection that makes reassembly impractical, with a 12-sheet throat and a bigger bin for households that shred often. Step up to this if the standard pick feels too small for your paper pile.

    View on Amazon
  • Identity Theft Protection Roller Stamp (3-Pack)

    Identity Theft Protection Roller Stamp (3-Pack)

    Roll over the name and address on mail before you toss it — no shredder needed.

    Why this works: Dumpster-diving for mail is still a common way identities get stolen. The roller stamps a scrambling pattern over names, addresses, and account numbers so they can't be read — a cheap, dorm-friendly alternative to a shredder, and an easy thing for parents to slip into a care package.

    View on Amazon
  • Identity Theft Prevention Roller

    Identity Theft Prevention Roller

    A single roller stamp — same scramble-the-mail protection.

    Why this works: Stamps a dense scrambling pattern over names, addresses, and account numbers on mail and labels, so a dumpster-diver can't read them. Same job as a shredder for anything you'd otherwise just toss.

    View on Amazon
  • Identity Protection Roller (Wide Coverage)

    Identity Protection Roller (Wide Coverage)

    Extra ink length for households with a lot of mail to scrub.

    Why this works: Same concealment principle as any identity roller, with a longer ink refill before it runs dry — the pick if you go through a lot of statements and packaging labels.

Physical Security

Low-tech theft in shared spaces is still theft. Lock it down.

  • Master Lock Portable Personal Safe (5900D)

    Master Lock Portable Personal Safe (5900D)

    A portable lockbox with a cable — secure a laptop, phone, or wallet in a dorm, locker, or hotel.

    Why this works: Opportunistic theft in shared spaces — dorms, gyms, hotels — is low-tech but common. This soft safe locks your valuables and tethers to a fixed object with its built-in cable, so a passerby can't just grab and walk off.
