ATLKey is a physical security key that can be used for:

• Two-factor / multi-factor authentication login (2FA / MFA)
• Passwordless login (Passkey / FIDO2)

It effectively protects against phishing attacks, account takeover, and weak-password risks.

It's very easy to get started.

ATLKey is plug-and-play — no extra software to install. Just plug it in and follow the on-screen instructions.

The metal touch button uses a capacitive design, so it's easy to tap even when plugged into tightly spaced ports; the USB-C connector is also designed to work with thick phone cases.

ATLKey supports all major systems and platforms, including:

• Operating systems: Windows, macOS, Linux, iOS, Android
• Browsers: Chrome, Edge, Safari, Firefox
• Common services: Google, Microsoft, Meta, Dropbox, and more

Actual support depends on whether each platform offers "security key / Passkey" settings.

OTP apps still require you to enter a password and a verification code, which can be tricked out of you by phishing sites.

ATLKey verifies with cryptographic keys — no codes to type. Login requires physically plugging in and touching the key, making it far more phishing-resistant.

ATLKey uses a USB-C connector and does not directly support Lightning iPhones (iPhone 14 and earlier). However, it can be used with an Apple official or compatible Lightning → USB-C adapter.
⚠️ Using an adapter may be slightly less convenient. If you have a USB-C device, we recommend using it directly for the best experience.

• Two-factor / multi-factor login, 2FA / MFA (U2F): unlimited in principle
• Passwordless login (Passkey / Resident Key): up to 100

• Passwordless login (Passkey) lets you sign in without typing a password — verification is completed directly with your security key.
• ATLKey supports FIDO2 Passkeys and can store up to 100 of them.

• Minimum 4 characters.
• We recommend 6–8 characters, mixing numbers and letters.

⚠️ Be sure to remember your PIN. Too many incorrect entries will lock the key, and it can only be restored by a reset — which erases all data.

No.

A reset erases all data on the key and cannot be undone. If you ever need to wipe all data, a reset is also the way to do it.

ATLKey comes with a one-year warranty. Within 12 months of purchase, you can request repair or replacement for defects not caused by misuse or accidental damage.

Recommended steps:

1. Sign in to your accounts using your backup ATLKey or another registered key.
2. Go to each platform's security settings and remove the lost key.
3. Register a new ATLKey.

⚠️ We strongly recommend registering at least one backup security key in advance.

If your primary key is lost, damaged, or locked, a backup key ensures you can still sign in to your accounts without interruption.

• PIN protection with limited retry attempts
• The key locks after repeated incorrect entries, preventing brute-force attacks
• PUF hardware-level tamper resistance

Example flow:
1️⃣ After several incorrect entries, the system asks you to unplug and re-insert the key.
2️⃣ After a certain number of repeated errors, you'll be required to enter your recovery phrase.
3️⃣ One more incorrect entry will permanently lock the key.

⚠️ The exact number of attempts may vary slightly by operating system.
⚠️ Once locked, the key can only be restored by a reset, which erases all data.

ATLKey features a one-piece, crush-resistant design, has passed water and dust resistance testing, requires no battery or network connection, and is built for everyday carry.

Yes. The USB-C connector and button are designed with thick cases in mind — just plug in and use.

On Windows, for example:
Settings → Accounts → Sign-in options → Security key → Manage, then follow the on-screen instructions.

⚠️ Resetting erases all data on the key.
⚠️ See the detailed setup guide for more.

Yes — SSH authentication is supported via the FIDO2 interface.

Yes. ATLKey has passed:

• FIDO2 L1 (CTAP2.1)
• U2F L1 certification

You can verify this on the FIDO Alliance website (Company: Atlancube LTD. / Product: ATLKey).

Yes. ATLKey's metadata has been uploaded to the FIDO MDS (Metadata Service), allowing platforms to verify the key's authenticity and security status.
