Featured Comments

For anyone who really thinks this way, let me give you a 30,000ft view of why this is wrong:

Which of the following passwords is easiest to memorize?

1. "SlickDeals2020"
2. "4 God So Loved The World"
3. "3!dFi&m_udhUfhhaAEJ75jf@HbzOpm37lauma_25381047361"

You've probably answered #1 or #2. Security professionals (hackers by another name) have tools that generate passwords. Without getting into the details, it would be beyond trivial to crack password #1. Password #2 would take longer, but since it is a passage in a popular book, the time it would take to crack it is reduced. Either one should take less than 1 day to compromise. (The first should take less than 10 minutes)

Password #3 is sufficiently random and has a very long length. It would take even the best known supercomputers *years* to crack that password. That makes it the best password of the 3, but obviously the most difficult to memorize.

That's what a passsword manager like LastPass, 1Password, Keychain with a YubiKey is for. You can generate wildly complex pass phrases that make accessing your data out of reach for most would-be hackers and secure all of that data with a physical hardware device that stays in your possession.

Yes, I hear you: "I haven't done anything wrong; the govt isn't cracking my passwords;I don't care if they get into my acct" and so on. Cool, I get it. Do you. Just know that using your spouse's name and 4 digits makes you the low-hanging fruit for somebody learning how to hack, let alone someone who is competent at their job.
In this case it's not the size that matters, but the technology behind it.
10% ca$hb@ck as well at a popular site. Saves about $9.50 on a 2-pack of NFC USB-C models. You can message me if you can't find it and want the exact name.

Note that you should always buy a minimum of 2, because if you ever lose a key you don't want to be locked out of your accounts. (should always have 2 associated).

Quote from wolfie14 :
I would like to know as well. The only difference I can see, as a complete noob to security keys, is that the 5 NFC says something like "works with most popular web tools" and the NFC just says "works with web tools."

I use Dashlane on my phone and desktop, although I'm considering a switch because they are forcing everyone to switch their browser extension and will no longer support the desktop app. Also, I wouldn't mind securing my google account, which I access through the iOS mail app and the gmail website. Can't think of anything else I'd really use it for as I don't do social media and as folks have mentioned, most banking websites aren't compatible, which I hope will change at some point.

That being said, what are the actual differences between the NFC and the 5 NFC other than the huge price difference? I'd really appreciate some input!

They don't seem to have a comparison tool but they have a tool to help you choose a key. The problem is, it keeps recommending me to to buy two keys, the 5 NFC and 5C, even though I am not selecting the option for USBc.
If you need time based OTP like how Authy or Microsoft Authenticator do (comparatively more websites support this type of authentication) or if you need to use the keys for login to computers, then only 5 series can perform this.

Else, the security key NFC would suffice for FIDO2 type authentication (like password managers, Google, Facebook etc. except for Lastpass premium which needs 5 series). Hope this simplifies a bit.

The NFC one cannot be used with Lastpass, correct? Need to get the 5 series instead?
Still with LastPass? Many moved to Bitwarden. The Security NFC works with Bitwarden.

Problem for me is that this only does 32 TOTP. I already have more than 32 sites that use TOTP. Returning mine. 32 limit may have been good 5-10 years ago, but it's 2020 and lots of sites use TOTP.

I thought U2F didn't work over NFC in bitwarden, has it been implemented recently?

Last I heard, Bitwarden U2F mobile support is planned for 2021.

This is the one issue with security keys, not many mobile apps support U2F (which is more secured than TOTP or Yubico's proprietary TOTP). I have to setup TOTP as a secondary authentication method, otherwise, I can't get into my accounts on my mobile apps.

I would like to understand something about the Yubikey 5 Series, It does support all the Multi security -protocol like the
( FIDO2/WebAuthn, U2F, Smart card, OpenPGP, OTP )
My primary goal here is to use one with Bitwarden premium on my mobile and laptop. How would you setup with KeePass and bitwarden

Can someone confirm that if we can use type A to type C converter if we buy USB-C or USB-A YubiKey?

For most people using MFA with google/m$ authenticator + unique complex password for every login is going to be sufficient. This effectively protects against brute force attacks and databases spilling credentials from sql injections and misconfigured policies. Even if they do get a password it's one password and you are banking on MFA or just limited impact since they would only have one password if not.

You start getting into very complex MITM attacks, or someone who has physical access to your phone that's a whole other game. We use yubikeys at work, they are fine but I believe they even increment on the models we have ( maybe all now ) so that even if somehow they were able to gain physical access and get the private key it would detect that from the counter and lock the account ( we are talking government level attacks almost at this point ).

There is the problem though, your credentials are only as good as the process on the server side, they can flip that setting and turn off MFA through an account recovery process which is often time weaker than the MFA by far.

I can confirm that you can use a usb-c yubikey, stick that into a usb-c to usb-a adapter and it would still work.

You can even stick that usb-a adapter into a usb-a hub and connect that to your computer and it will still work.

For those that happen to want the 5Ci add 2 free 2 blue nfc keys. You can also add another 5 series and get the $20 off.

If anyone wants to order only 1 key and wants to avoid shipping costs, just add the lanyard for $1 & the shipping becomes free.
