Is yubico setup for one fingerprint or two? If one, what happens when finger is cut or burned on grill?

Yubico not support fingerprints. It is use for accept human presence. So if you insert yubico in pc or use nfc on smartphone. You can add "required touch" for every authentication operation. Touch approve that it is operation accept by real people. There is not a zero chance, if you do not confirm the action with a touch, then the attacker can use your yubico without your knowledge when you left it in the computer. This mechanism is designed to protect against such attacks.

This is an extremely common device. Why are there only 17 reviews, and even fewer for other Yubico devices?

Likely because people value convenience over security, and this is a secure device. Also, the bad reviews that I've scanned come from people who simply do not understand what multi-factor access means. This device augments your username and password (that which you KNOW) with the device itself (that which you HAVE). When used correctly, if your password is compromised it does an attacker no good unless they have the device as well. for myself, I used separate passwords for various purposes, so a single breach will not place at risk my other accounts. And most are not protected by MFA, since thet are trivial. But for VPN access into my home, and finance accounts, I do use hardware based MFA. A small price to pay for the added protection when there are significant consequences to a single breach.

can a pair of these be set up so one can be used as an emergency backup if the first one is lost?

If you are buying this, you should buy two. Yes, using a second one as a backup is exactly what you want to do. Otherwise, if the first gets lost or broken, you are locked out of the accounts you set up.

Can you use this to auto-fill your passwords so you don't have to remember any?

The YubiKey 5 is a FIDO2-capable key - which does replace password usage in many applications. From the FIDO Alliance website: "FIDO2 cryptographic login credentials are unique across every website, never leave the user’s device and are never stored on a server. This security model eliminates the risks of phishing, all forms of password theft and replay attacks."

人**当

必須

引っ張り出して何度も使う物では無いので物足りないと思います。google authenticatorからyubico authenticatorへ引っ越す理由がクラウドではなく完全ローカルだったからです。ローカル運用が出来るだけでも価値はあると思います。

ウェブで確認すること

使い方の説明書はついていない。ウェブや動画でキーの使い方を確認することが必要だが、日本語がすくないのでよく理解してから導入するように。yubico authenticatorはよいが、computer login toolsは危険。実際に、一時アカウントにアクセスできなくなった。

初めての導入

Windowsで使用してみました。ネット検索にめっちゃやり方が記してありやり方を理解すればスムーズにいけました。一度、ピンを忘れてしまいロックがかかりましたが、リセット、再設定で大丈夫でした。Yubicoパスキーは最初からやり直しになりますが、パスワードをバックアップしておくことでなんとか大丈夫でした。

どんどん厳しくなるログイン用

昨今証券会社や銀行のログインが厳しくなり、セキュリティキーが必要になったため、色々調べてこちらを購入他よりも高額ですが、品物の特性上耐久性や信頼性の高い物を選ぶべきだと思いました

ファームウェアのバージョンアップが出来ない

ファームウェアのバージョンが5.4.3と古く、最新版の5.7.4ではなかったです。アップデートが出来ないので、どうしようも出来ないです。 5.7.4じゃないと返品対象です。在庫がはけていないところから購入するとこうなったのかなと思っています。

認証に便利 USBスロットの位置によっては指タッチしにくい

仕事のログインで必要になり購入。特別な知識は持ち合わせていないが、ちゃんと使えていて助かっている。ただ、新しく買ったデスクトップパソコンの側面にあるUSBスロットが画面のやや内側にあるため、挿し込んだ後、指が画面との間に入らずタッチできない。挿し込みやすいようUSBハブを追加購入した。
