Maybe there is a market for minuscule TOTP devices. Just 7 segment displays for the code and the lowest res camera that can decode a QR code.

Or even lower-powered? https://www.amazon.com/Token2-miniOTP-2-NFC-programmable-Two...

I remember my dad worked at a bank in the 90s and had one shaped like this to enter one of the buildings: https://www.amazon.com/HyperOTP-Time-Based-6-Digit-Services-...

Yeah RSA made these for a looong time.

But if you don't have a phone to program it you'd need a camera or some way to manually enter the data.

FIDO2 Security keys should be considered good "hardware tokens" now , more phishing-resistant than TOTP
