I've gone from my first prototype to a custom PCB connector board. This is a NiceTOTP device.

It's a standalone TOTP device. After the initial setup, no phone nor computer is required. It doesn't do passwords, just TOTP. A code is entered with the two buttons to unlock it, then you can flip through your accounts. If you wanted to build just one unit, it'd be about $60 USD in parts ($50 w/o a battery).

Self-custody is the only true freedom. You build the keys, you hold the door. As Marcus said, he who commands himself is free. Keep forging.

Neat build. Under the hood, TOTP as defined in RFC 6238 divides the current Unix timestamp by a time step, 30 seconds by default, to produce the counter that generates each code.
