Question Can hardware bound credentials reduce session theft and token replay?

Hardware-backed credentials can make stolen secrets less useful because an attacker cannot complete the necessary cryptographic operation without access to the authenticator. That provides meaningful protection against several credential-phishing and replay scenarios, but the benefit can weaken if the post-authentication session or refresh token remains a portable bearer artifact.

Hardware binding clearly strengthens initial authentication. Reducing session theft and token replay after login usually requires the application or authorization server to enforce sender-constrained tokens, proof of possession, or another mechanism that binds use of the token to a device-held key.

How are teams balancing this additional protection with lost-device recovery, shared administrative workflows, break-glass access, browser compatibility, and endpoint-compromise risk?

Maybe

Depends on if the software periodically re-authenticate using the hardware or not, the hardware itself just to prove that it has participate in the authentication process and doesn't really prove that it's still there after it has authenticated

“How are teams balancing this”

hmm I smell a bot
