Unable to see the Reset Security Token option                 

There are a few different reasons the Reset Security Token feature may not be available. 

1. IP Restrictions in the Login IP Ranges
2. Network Access missing from Security Controls
3. User Profile is Corrupted

• IP Restrictions in the Login IP Ranges

          In order for the Reset My Security Token option to appear, you will need to remove the Login IP Ranges or change the User to a profile that does not have Login IP Ranges listed.

 

• Network Access missing from Security Controls

    System administrators can confirm if Network Access is missing by following these steps:

1. Go to Setup
2. On the Quick Find box, enter Network Access.
3. If you don't see the 'Network Access' link above, the system administrator can log a Case with Support to request the following features enabled for the organization:
4. Login Challenge Enabled
5. Login with API Token

• User Profile is Corrupted

         If none of the previous scenarios are true try editing the User profile that's missing the security token and save it without making any modifications. This will reset the profile and might result in the token option being available.
