The short version
Key points
- The YubiKey 5C NFC uses a physical key to authenticate logins after a password is entered.
- It connects through USB-C or NFC, with support across Mac, Windows, Android and iOS devices under the conditions described.
- The key does not require batteries, mobile reception or an authenticator app.
- Hardware-key support varies between services, so compatibility should be checked before purchase.
- Registering two keys is recommended so losing one does not leave an account dependent on lengthy recovery processes.
What the YubiKey 5C NFC does
A YubiKey provides an additional layer of protection for online accounts. A password alone can be exposed through phishing, a data breach or guessing, but a hardware key requires the person logging in to also possess the physical device.
During setup, a security key is added through an account’s security settings. When prompted during a login, the user plugs in the YubiKey or taps it against a compatible phone, then touches the key’s metal button area to confirm the authentication. TechManPat says there are no codes to copy and no separate app to open.
Connectivity and device support
The YubiKey 5C NFC reviewed in the video has a USB-C connector and NFC support. The USB-C connection is intended for laptops, desktops and compatible phones, while NFC allows the key to be tapped against a mobile phone.
The video demonstrates the key with a MacBook, a Windows computer and an Android phone. It also states that the key works with iPhones, although iOS 16 or newer is required for NFC functionality. An adapter can be used to connect it to a phone without USB-C.
The key was set up with Google, Facebook, LinkedIn, GitHub and Bitwarden in the video. The transcript also names Apple, Microsoft, Twitter, Dropbox and 1Password among supported services, while noting that the compatibility list should be checked before buying.
Why use a physical security key?
Unlike SMS-based authentication, the YubiKey does not depend on mobile reception. It also does not require batteries, a third-party authenticator app or cloud-stored codes. Once configured, many services only request the key when signing in from a new device or browser, or after detecting suspicious activity.
The physical requirement can help protect against phishing, SIM swapping and remote attacks, because knowing the password alone is not enough to complete the login. The video also describes the device as small and solid, and says it is waterproof and crushproof.
Limitations and backup planning
The price is identified in the video as $110 Australian per key. TechManPat also says that setting up two keys represents an initial investment of $220. The transcript presents the cost as a consideration for buyers, particularly when compared with the potential difficulty of recovering from identity theft or compromised accounts.
There is also a learning curve for people accustomed to SMS codes or authenticator apps. More importantly, not every service supports hardware security keys. The video says most major platforms do, but some banks, government services and smaller websites may not yet support them.
A second key is recommended. If the primary key is lost and no backup has been registered, some services may require a lengthy account-recovery process or could lock the user out. The suggested approach is to keep one key on a keyring and store the other in a drawer or safe.
Who may benefit from one?
The video positions the YubiKey as particularly relevant for business owners, IT workers, people handling client data, online creators, cryptocurrency or share traders, and anyone wanting stronger protection for an email account or password manager. Securing email is highlighted because password recovery for other accounts commonly relies on email access.
The key may also suit people who find authentication apps or one-time codes confusing, although every account still needs to support hardware-key authentication. Checking the service list first remains an important part of deciding whether it is suitable.
TechManPat’s conclusion
I have set the YubiKey up on my critical accounts and, in my view, it has become part of my security kit. I no longer worry as much about a password appearing in another leak because the key is still required. If you value stronger protection for important online accounts, I think you should consider getting one, or more realistically two, and set them up properly and store them safely.
