The internet identity the supported devices

when I try to login from PC the internet identity required me to use USBput from my iPhone or from my mac work just fine what if someone have an old device?

If a device lacks a TPM (Trusted Platform Module) security chip, you can still log in with Internet Identity by using another device for confirmation.

For example, I use my phone to confirm my login when accessing my ‘TV PC,’ which is over a decade old and doesn’t have a TPM chip.

With PC do you mean a Windows? In that case make sure Windows Hello has been enabled.

Yes I tried on windows PC, and it ask to use USB

Are you able to go through the 6 steps at https://webauthn.me without it asking to use USB?
