# Credential Manager - [Associating and Dissociating Monitors](https://www.manageengine.com/products/applications_manager/help/credential-manager.html#associate-dissociate) - [Credential Management in the Enterprise Edition](https://www.manageengine.com/products/applications_manager/help/credential-manager.html#enterprise-edition) - [Credential Sync in Plugin Edition (OPM to APM)](https://www.manageengine.com/products/applications_manager/help/credential-manager.html#credential-sync) - [Credential Manager APIs](https://www.manageengine.com/products/applications_manager/help/credential-manager-apis.html) Credential Manager in Applications Manager will help you to store the various credentials like password, SNMP community, port, etc., for all type of monitors in a common place. This pre-configuration of credentials in a central location will help in avoiding the need to edit every monitor when a password or SNMP/ SSH info changes. For instance, you can create a credential for type MySQL monitors. Consider the name of the credential is SampleMySQL. This SampleMySQL contains parameters for MySQL monitor, username, password and database name. When you want to add a MySQL monitor, credentials of type MySQL alone will be displayed. On selecting the name SampleMySQL, the parameter for this credential will be associated internally to this monitor and it gets added. You need not give the user and database name separately. When more monitors, say 20 monitors for MySQL type is added with the same Credential Name (SampleMySQL), it is easier for a user to maintain all of these in a single place. Any change in this credential, will be reflected to all the monitors associated with the credential. The credential manager support is available for servers, databases and application server monitors. 1. In the **Settings** tab navigate **Discovery and Data Collection** → **Credential Settings** → **Credential Manager**. 2. Click **Add Credential**. 3. Select the **Credential Type**. When a type is selected, fields associated to that type is displayed. You need to create a profile based on the type required. 4. Provide a **Credential Name**. This name is used to associate credentials to monitors during discovery of monitors. When this name is mentioned, all the properties associated with this name will be associated to the monitor. 5. Provide other details like the **Username** and **Password**. More fields are displayed as per the credential type selected. 6. Click **Save** to add the credentials. You can edit or delete these credentials from the details page by clicking on the respective icons on mouse hover of a particular credential name. ## Associating and Dissociating Monitors Credential Manager provides an option to bulk associate monitors with credentials. ### To associate monitors 1. Go to **Settings** → **Credential Settings** → **Credential Manager**. 2. Click the **Monitor** icon for the required credential. 3. Enable **Show all monitors of this type** to view all available monitors that can use the credential. 4. Select monitors and click **Associate**. ### To dissociate monitors 1. Open the **Associated Monitors** window. 2. Select the monitors to be removed. 3. Click **Dissociate**. ## Credential Management in the Enterprise Edition You can add, edit or delete a credential from the Central Server in Applications Manager, the same as in the Professional Edition, and the credentials get automatically synced with the Probe Servers. However, these credentials cannot be edited from the Probe Servers. ## Credential Sync in Plugin Edition (OPM to APM) In the Plugin Edition, credentials created in OpManager (OPM) are automatically synchronized with the Applications Manager (APM) plugin. These synced credentials are read-only in APM and cannot be edited or deleted from the APM plugin. Any modifications must be performed directly in OpManager. To ensure uniqueness and easy identification, credential names synced from OPM are suffixed with **~OPM**. These credentials can be used in the same way as locally created APM credentials and can be associated with monitors during configuration. ### Supported credential types The following credential types are supported for OPM to APM credential synchronization: | S.No | Credential Type (In OPM) | Credential Type (In APM) | |---|---|---| | 1 | Windows / WMI | WMI | | 2 | Telnet / SSH | SSH | | 3 | Telnet / SSH | TELNET | | 4 | SNMP v1/v2c | SNMP v1v2 | | 5 | SNMP v3 | SNMP v3 | | 6 | VMWare | VMWare ESX/ESXi | | 7 | Citrix | Citrix Hypervisor | | 8 | UCS | Cisco UCS | | 9 | Nutanix | Nutanix | | 10 | REST API | REST API |
