Should the Yubico Authenticator show the websites and applications that the YubiKey is configured for?

CyberKey: A Biometric TOTP Hardware Key

Hi everyone!

I wanted to share my first embedded project. It's very similar to a yubikey! CyberKey is an open-source, fingerprint-protected hardware authenticator.

It stores your TOTP secrets securely and only reveals/types them after a successful fingerprint scan. Instead of just showing the code on the screen, it acts as a Bluetooth Keyboard. With one tap, it types your 6-digit OTP directly into your computer or phone.

The M5StickC Plus 2 was the perfect form factor. It’s pocketable, has a great display for the UI, and it's easy to integrate the fingerprint sensor. I wanted to build something that feels like a real-world "cyber" tool: utilitarian, secure, and futuristic.

Tech Stack:

  • Hardware: M5StickC Plus 2 + Fingerprint Unit sensor from M5Stack.
  • Language: Rust (ESP-IDF + no_std core logic).
  • Crates: I’ve split the project into portable crates (TOTP engine, Fingerprint driver, HID tables) so they can be tested and reused easily.
  • Custom UI: I implemented a custom proportional font system (using Orbitron) to give it a high-tech, functional aesthetic.

If you have any questions, don't hesitate!

do Yubikey supports pin over NFC now in Android for passkey?

I did know Yubikey do not support pin over NFC in android, but iOS does.
From yesterday I noticed it supports on android too.

Can anyone reccomend a thorough guide to passkey use and best methods of implementation? I am absolutely new to this topic. I can do the reading and follow instructions from them. Is it a consensus here that passkeys are the best option available in May, 2026? This is a big ask. As a 74 yr. old, I offer all the gratitude I have cultivated over the years to you for helping with this.

Hi

I just bought afew yubikey 5c series and use them for 2fa codes and passkeys.

And my second slot is empty

Any idea what else I can use these keys more efficiently apart from 2fa and passkey for everyday use.

Ps: I see people use the challange response for offline kpass .
I use btw already so no intention of moving to kpass

Thanks,

Hi all,

I am in charge of deploying Yubi Keys company wide for around 1200 users. I found YubiEnroll, and it works great for pre-provisioning keys before giving them to the user. The issue is even with a short script to speed up the process, it still requires a lot of manual effort such as tapping the key several times, unplugging it and plugging it back up, etc.

Has anyone dealt with this and figured out a way to fully automate the provisioning? My ideal goal would be to have a CSV file with every user, then a script just goes one by one, provisions the key, and then waits for a new key to be plugged in before continuing. I have reached out to YubiKey support but was told this request was "out of scope" of their support. I read the YubiEnroll documentation, but did not see an answer or way to script this.

Hi there I'm at the end of the configuration, pins changed, management key changed, certificates done and keys generated... But when it's asking me to pair yubikey is where I am at a loss.

1st I don't see the alert at the top right of the screen, I get that one would manually pair but,

2nd do I need to purchase a smart card from somewhere to make all of this happen?

Thanks
