Use ALMS to Change ACEmanager Password for a Fleet of Devices

The Airlink Management Service (ALMS) is a secure cloud-based device management application that makes it easy to configure and update any number of Sierra Wireless gateways remotely. If you have multiple gateways and do not currently subscribe to ALMS, you can sign up (max of 15 devices for free tier of ALMS) by visiting our website link: ALMS Management Software

For updating ACEmanager passwords from ALMS via the normal “device initiated” setup (this is where the modem checks in to ALMS on a regular interval for providing status and retrieving any settings changes), step by step instructions are detailed here: How To Update ACEmanager Passwords from ALMS

Note: For gateways communicating using MSCI protocol, you will need to first initialize the current password in ALMS.
