Prior to SEE FD 8.0, to enable the OTP Communication Unlock feature, you must turn on the OTP Communication Unlock setting via GPO. There is no way to enable this when creating your client packages in all GE/SEE versions prior to version SEE 8.0. This would include ALL GuardianEdge branded releases and any SEE releases before 8.0.
Additionally, it is useful to note that the policy is a User policy and will need to be applied to a User Group in AD.
Create a new GPO or modify an existing GPO and under User Configuration > Software Settings > GE/SEE > Framework > One-Time Password, you can check the box to enable OTP Communication Unlock.
