What it checks
Security keys should be the primary 2SV method. SMS and voice-based 2SV are vulnerable to SIM-swapping and interception attacks
Recommended value
Security keys enforced as primary method
Remediation
Admin Console > Security > Authentication > 2-step verification > Set allowed methods to 'Security key only'
