What’s New

Version 2.13.2

This release introduces the One Time Password (OTP) code for the Enhanced Client Security feature. When the Enhanced Client Security feature is enabled, Umetrix Data Server verifies whether the email address you specify when logging in exists in the User Directory and that the account status is “Active.” If you entered a valid email address that is active, Umetrix Data Server will send an OTP code to the email address associated with the login you entered. You must access this email message and enter the OTP code in the One Time Password dialog box provided by the Umetrix Data app. Umetrix Data Server will reject the login if any of the following conditions occur:
• You enter an invalid email address.
• The account associated with the email address is not active.
• You enter an incorrect OTP code.
This enhancement is optional. You must contact Spirent Support to activate Enhanced Client Security for your activation code.

User agreement?!!

All I wanted to do before downloading this app was to check my connection speed. However, before doing so I was faced with having to first agree to some legal list of requirements and disclaimers. Honestly I didn't even read much of it, thinking to myself, why do I need to agree to this junk to just check my Internet speed. Downloaded--deleted.
