Using proper installation techniques maintains physical stability across daily activities.

This key packs several authentication standards into one small body, which is why it turns up across so many different account types.

• FIDO2/WebAuthn and FIDO U2F cover modern passwordless and two-factor logins on services like Google, Microsoft and GitHub
• Yubico OTP and OATH-TOTP/HOTP generate one-time codes for services that still rely on classic two-factor setups
• Smart card (PIV) support lets IT teams use it for certificate-based sign-in on managed corporate laptops
• OpenPGP support handles email signing and encryption workflows for users who manage their own keys

Because all of these live on one physical key, a single unit can replace several different authentication apps and hardware tokens at once.

Getting started does not require installing drivers on most modern computers and phones, since the key registers itself the moment it is plugged in or tapped.

• Plug into a USB-C port and tap the contact to confirm a login, or hold it near an NFC-enabled phone for the same result
• No batteries and no internet connection are needed for the key itself to function
• The Yubico Authenticator app adds a companion interface for managing stored credentials on desktop and mobile
• Each supported account needs to be registered individually through that account's own security settings page

Because the key has no screen, all setup confirmation happens on the device or account being secured, not on the key itself.

A single hardware key is only useful if it is on hand, which is why most guidance around this category centers on keeping a second one in reserve.

• Remote workers and admins managing sensitive accounts benefit from registering both a primary and a spare key on every service
• Freelancers juggling client logins can dedicate one key to work accounts and keep a personal key separate
• Households sharing a family email or financial account can register one key per adult so no single person becomes a bottleneck
• Anyone who travels frequently should store the spare key somewhere other than the bag carrying the primary one

Losing the only registered key without a backup usually means going through each service's account-recovery process from scratch.

The YubiKey 5C supports a wide protocol set: FIDO2/WebAuthn, FIDO U2F, Yubico OTP, OATH-TOTP/HOTP, Smart card (PIV), and OpenPGP, covering both passwordless and multi-factor authentication methods.

• Compatible with over 1,000 accounts, including Google, Microsoft, and Apple
• Works with the Yubico Authenticator app across mobile and desktop
• No batteries or internet connection needed to authenticate

Because it supports this many protocols on one physical key, the same device can replace a phone authenticator app for TOTP codes, serve as a FIDO2 passkey, and act as a PIV smart card for enterprise systems, rather than needing separate hardware for each use case.

The key is built from tough, waterproof, and crush-resistant materials with no batteries and no moving parts to wear out.

• Manufactured in Sweden and programmed in the USA
• USB-C connector plugs directly into laptops, tablets, and phones with a USB-C port
• Tap to authenticate once inserted, with no software installation required for basic use

The lack of an NFC antenna on this specific 5C model means it cannot be tapped against NFC-enabled phones the way the 5C NFC variant can, so anyone wanting wireless tap authentication on a phone should confirm they are ordering the NFC-equipped version instead. Buyers on USB-A-only older machines will also need a USB-C to USB-A adapter to use this connector.

Setup involves registering the key with each account's security settings, after which it can be plugged in and tapped to complete sign-in.

• No extra fees or subscriptions are required to use the key once purchased
• Yubico recommends buying two keys, one for daily use and one as a spare
• PIV and OpenPGP functions can be configured for enterprise or developer workflows

Because a hardware key is a single physical object, losing it without a registered backup means being locked out of any account that requires it until an alternate recovery method is used. Setting up a second YubiKey as a spare, and storing it somewhere separate from the primary key, is the practice Yubico itself recommends to avoid this scenario.

The YubiKey 5 Nano C supports a broader protocol set than entry-level keys, covering FIDO2/WebAuthn, FIDO U2F, one-time password protocols, smart card (PIV) and OpenPGP.

• Compatible with 1000+ services including Google, Microsoft and Apple accounts
• A single key can be registered to 100+ individual accounts
• Passwordless, strong two-factor and strong multi-factor authentication methods are all supported

That wider protocol support is the main difference versus entry-level security keys, making the 5 Nano C a fit for users with legacy systems that still require OTP or smart card authentication alongside newer passkey logins.

Designed to sit flush in a USB-C port, the Nano form factor is built for a near-permanent connection rather than a keychain carry.

• No NFC support on this model, unlike standard-size keychain versions
• Authentication happens with a simple tap once the key is inserted
• The compact size minimizes how far the key protrudes from a laptop or desktop port

This makes it well suited to a laptop that stays mostly on a desk, where leaving the key inserted is convenient, but less practical for switching between multiple devices throughout the day compared with a keychain-style key that unplugs easily.

Water resistant to IP68 and crush resistant, with no batteries or moving parts, the key is built to hold up to daily wear.

• Manufactured in Sweden and programmed in the USA
• Because the Nano form factor sits inside the port, it is easier to lose track of if removed and set down elsewhere
• A primary and spare key are recommended for each account to avoid lockout

Given the compact size, keeping the spare key somewhere distinct and clearly labeled matters more here than with a bulkier keychain key, since a small nano-format key is easier to misplace once separated from a device.

This key uses the FIDO2/WebAuthn and FIDO U2F passkey standards to provide phishing-resistant authentication, connecting either by plugging into a USB-A port or by tapping against an NFC-enabled phone. It is built for passkey and second-factor login rather than password generation.

• Standards: FIDO2/WebAuthn, FIDO U2F
• Connection: USB-A plug-in or NFC tap
• No OTP (One-Time Password) support
• Compatible with 1,000+ accounts and services

Because authentication happens through a physical cryptographic exchange rather than a code you type in, phishing sites that try to capture a login code cannot use it to access the account. The lack of OTP support is a deliberate simplification on this Basic Compatibility model, and services that require OTP codes specifically will need the YubiKey 5 Series instead.

Setup involves registering the key with each account's security settings individually, after which login requires plugging in and tapping the key (USB-A) or holding it against a phone's NFC sensor. No app, battery, or internet connection is needed for the key itself to function.

• No batteries or charging required
• No internet connection needed for the key to work
• Registration required per account/service
• Optional Yubico Authenticator app for passkey and PIN management

Because the key has no battery, it is always ready to use, but that also means there is no on-device screen or status indicator beyond a touch sensor and LED. Setting it up as a primary and keeping a second key as backup avoids a lockout scenario if the primary key is lost, since each account needs its registered key present at login.

Built from waterproof and crush-resistant materials, the key is designed to survive being carried on a keychain daily rather than kept protected in a drawer. It works across major platforms including Google, Microsoft, and Apple account ecosystems.

• Waterproof and crush-resistant housing
• No moving parts or battery to wear out
• Broad platform support: Google, Microsoft, Apple, password managers
• Manufactured in Sweden, programmed in the USA

The rugged housing suits keychain carry for daily use across a laptop and a phone, but the USB-A-only connector on this model means devices with USB-C-only ports, such as many current laptops and phones, need a separate adapter for the plug-in connection method; NFC tap remains available on supported phones regardless of port type.

The Security Key C NFC supports the FIDO2/WebAuthn and FIDO U2F passkey standards, compatible with Google, Microsoft and Apple accounts among 1000+ supported services.

• A single key can be registered across up to 100 of a user's own accounts
• One-time password protocols are not supported on this model
• For OTP or smart card (PIV) support, a higher-tier 5 Series key is the alternative

This makes the Security Key C NFC a fit for straightforward passwordless and two-factor logins rather than broader protocol coverage, which matters for anyone with legacy accounts still requiring OTP codes.

Authentication works through either a USB-C plug-in tap or an NFC tap against a compatible phone.

• No batteries or internet connection are required to authenticate
• The dual connection method covers both laptop logins and mobile NFC taps without carrying two devices
• USB-C is the only wired interface; USB-A ports need a separate adapter

Because the key works offline, it continues to authenticate even during a network outage on the device asking for the tap, which sets it apart from app-based two-factor codes. Daily use amounts to plugging in or tapping the key whenever a supported login prompts for it.

Built from waterproof, crush-resistant materials, the key is designed to survive being carried on a keychain daily.

• Manufactured in Sweden and programmed in the USA under stated security standards
• No moving parts or battery means less to wear out over time
• A primary and spare key are recommended for each account

That backup-key recommendation is worth planning for up front, since losing the only registered security key can complicate regaining account access. Buying and registering a second key at setup avoids that scenario later, though it does mean a second unit to purchase and keep somewhere safe.

No installation needed. The card is passive—insert into a compatible FIDO2 USB reader or tap against an NFC reader on compatible smartphones and web services. Windows Hello for Business and macOS support contactless authentication via NFC-enabled devices.

Building access requires integrating with existing card access control systems. IT departments can enroll the card's MIFARE ID into door readers. The dual interface supports both modern NFC-enabled systems and legacy magnetic readers with adapter cables.

Hardware-based FIDO2 keys prevent phishing attacks by cryptographically signing challenges only for registered domains—attackers cannot redirect authentication to fake sites. The NXP secure element is tamper-resistant, meeting FIPS 140-2 Level 3 for government-grade key storage.

All encryption uses AES standards certified under Common Criteria EAL 6, the highest practical security assurance level. The card stores 128-bit cryptographic keys that never leave the chip during authentication. No passwords are transmitted over networks.

Confirm your critical online services support FIDO2 before purchase. Check accounts at Google, Microsoft, Amazon, GitHub, and your bank's website for 'Security Key' or 'Passkey' enrollment options. Not all services support hardware keys—legacy systems may continue requiring passwords.

For building access, coordinate with your organization's IT/security team to enable the card in access control systems. Backup card recommended; losing a single hardware key creates temporary access gaps until IT can disable it and reissue.

First-time setup requires a dedicated Key Manager application on a PC or Mac before the key can be initialized. Once set up, it works across USB-A, USB-C, and NFC on mobile devices, covering Windows, MacOS, and Linux for FIDO2 login and 2FA.

• Initial key setup must run through the Key Manager application on desktop first
• Works via USB-A and USB-C ports plus NFC for supported mobile devices
• Windows Hello support is limited to Enterprise editions with Entra ID

Because NFC only functions through mobile authentication, MacOS and Windows users need a physical USB connection rather than a tap to authenticate.

The key stores up to 50 passkey slots and 50 OATH slots for two-factor codes, using SHA256, AES, HMAC, ECDH, and ECDSA algorithms. It carries CE, FCC, RoHS, WEEE, and FIDO2 Level 1 certification.

• 50 passkey slots and 50 OATH slots stored directly on the key
• 360-degree rotating metal cover adds water, tamper, and crush resistance
• Certified to FIDO2 Level 1, not the higher Level 2 standard some government systems require

Because it is rated FIDO2 Level 1 rather than Level 2, services requiring the higher tier, such as ID Austria, are explicitly not supported by this key.

The key works with major productivity accounts including Google, Microsoft, and Zoho, password managers like 1Password, Dashlane, Keeper and LastPass, and social platforms including Instagram, Facebook, X, and YouTube. It also stores a built-in password manager.

• Productivity accounts: Google, Microsoft, and Zoho account login
• Password managers: 1Password, Dashlane Premium, Keeper, and LastPass Premium
• Online shopping and social accounts: Amazon, Best Buy, Instagram, Facebook, X, and YouTube

For banking, the key is compatible exclusively with the web version of one major bank's system and does not work with the app-based version.
