TouchPass Basic2
One touch, securely open
The smallest module in the series: a capacitive fingerprint module with a ring indicator plus a single USB port, ready the moment you plug it in. One fingerprint carries all three hardware-level authentication methods — HID password entry, PIV smart card and PassKey — and passwords and keys never leave the device.
One fingerprint, three kinds of authentication
The fingerprint is the device's single means of authentication. Every enrolled fingerprint can sign in to the app, open a PIV session and complete PassKey verification — you don't need to assign roles to your fingers.
Bind a password to a fingerprint. On a successful match the device types it out character by character over the standard USB keyboard protocol. All the system sees is an ordinary keyboard.
- Works in login boxes, apps, web forms and terminals
- Write-only — not even the app can read the password back
- Optional auto-Enter submits as soon as typing finishes
The device enumerates as a standard PIV smart card (CCID): macOS login and lock-screen unlock, enterprise certificate sign-in and code signing all work.
- ECC P-256 keys generated inside slots 9A / 9D
- The PIN field is filled in by the device — nothing to memorise
- Every use requires a fresh fingerprint (30-second session)
Register and use passkeys straight from the browser: no passwords, no verification codes — one touch signs you in. The credential's private key stays in the device's encrypted partition.
- CTAP 2.0 / 2.1, backwards compatible with U2F
- Up to 256 discoverable credentials
- The fingerprint handles user verification — no PIN out of the box
One exception: if you set an HID password containing letters or symbols for a given fingerprint, that fingerprint can no longer be used for PIV — the macOS smart-card PIN field accepts digits only. Fingerprints with no password, or with a numeric password of 6 digits or more, are unaffected.
How it works
The actual steps for all three capabilities — every one of them is configured in the TouchPass app.
Sign in to the TouchPass app, choose “Set password” on the fingerprint card, enter the password you want to bind and save. Once saved it cannot be read back — only overwritten or deleted.
Put the cursor in the target password field. The device only types the password into whatever currently has focus, so check the focus before you touch.
A green flash and a short buzz mean the password has been entered; by default a Return is appended to submit it. Keyboard output is US-layout ASCII.
Assume it is already in an attacker's hands
They have a soldering iron, a programmer, an oscilloscope and time. Even then they still cannot get your password — from the choice of silicon to the last step of factory programming, the entire chain is designed around that one assumption.
Fingerprint templates never leave the module, are stored encrypted, and there is no image export interface. A custom module, paired one-to-one with its own MCU.
Three kinds of PIN, one job each
The PINs on the device are independent of one another, and day to day there is only the first one you actually have to remember.
This is the last line of defence once the device has been stolen. The failure count is stored persistently and survives a power cycle; any successful sign-in (PIN or fingerprint) resets it to zero. On by default — we do not recommend turning it off.
First thing out of the box: set the admin PIN. The device ships without one, and a factory reset clears it again — until it is set, the management channel is wide open. Make it long; don't settle for four digits.
Up and running in three steps
Plug TouchPass Basic2 into a USB port. HID and PassKey are driver-free on every platform — there is nothing to install.
Open the TouchPass app, set the admin PIN, then lift and press five times to capture the print; set an HID password or initialise PIV as needed.
Touch the sensor to type a password, unlock your Mac, or complete PassKey verification.
The light and the buzz are the whole interface
There is no visible LED on the body; every state is expressed by the fingerprint module's RGB ring light and the vibration motor. Vibration can be turned off in the app, and the idle breathing light supports custom colours and rhythms.
