Error: SecureAuth.OTP.TotpToken.VerifyOtp: Exception: Object reference not set to an instance of an object.

Follow

SecureAuth IdP Version Affected:  9.1,9.2

 

Description:  

 

Devices enrolled with OATH Token stored as either "JSON" or "JSON Encrypted" can successfully register/enrol but the TOTP never matches for subsequent logon attempts.

The Error log will contain this solitary error:

SecureAuth.OTP.TotpToken.VerifyOtp: Exception: Object reference not set to an instance of an object.

Storing OATH Token as Plain Binary works correctly and allows TOTP authentication to succeed.

 

Cause:  

Product defect EE-997

 

 

Resolution: 

 

Addressed in hotfix 9.2.0-20
