Looking for a security token with 0-9 (zero - nine)


I’m looking for a security token that has 0-9 (zero through nine) keypad. You must input the code digits to unlock a computer. Similar to a digital key.
We have a computer that never touches the internet, no Wi-Fi, Bluetooth, etc.
No cell phones are allowed in the test room. Basically, no communication devices that can be used for U2F, 2FA or MFA (authentications).
I looking for a token that you can input a set number of digits in a specific order that when inserted into the USB/Thunderbolt will allow/deny access to the asset.
