Another option is a TPM-based authenticator.  Would this be acceptable?

No. TPM 2.0 chip is a *proprietary* black box. Some of them have known critical security vulnerabilities[1].

OK, but so is every onther secure processor (yubikeys, finians, etc). At least TPM2 is ubiquitous, and watched/tested widely, and being improved as a result. The vulnerability you refer to was due to not encrypting LPC traffic between the motherboard and the TPM chip, which was apparently due to the implementation being lazy rather than a TPM deficiency. Traffic encryption is a standard protocol feature, and is increasingly being used.
