2026 Enterprise logins (Google/Microsoft) require a "Hardware Attestation" (TPM). You can't spoof this easily.
The Bypass:

• Bridge Hijacking: Instead of a direct attack, use a "Bridge Config" to prompt a real user (via social engineering or task-sites) to "Authorize Device."
  
• Refresh Token Capture: Once authorized, capture the OIDC Refresh Token. These tokens are "Pre-Attested" and allow you to bypass hardware checks for 90 days on that specific session.
