# Secure Credential Store Plug-in for Zowe CLI
The Secure Credential Store (SCS) Plug-in for Zowe CLI lets you store your credentials securely in the credential manager of your operating system. The plug-in invokes a native Node module, keytar (opens new window), that manages user IDs and passwords in a credential manager.
# Use Cases
Zowe CLI stores credentials (mainframe username and password) in plaintext on your computer by default. You can use the SCS plug-in to store credentials more securely and prevent your credentials from being compromised as a result of a malware attack or unlawful actions by others.
For detailed command, actions, and option documentation for this plug-in, see our Web Help (available online or as PDF or ZIP):

Note: Existing user profiles are not automatically updated to securely store credentials.
The plug-in introduces a new command group,
zowe scs, that lets you update existing user profiles and enable/disable the plug-in.
# Securing your credentials
User profiles that you create after installing the plug-in will automatically store your credentials securely.
To secure credentials in existing user profiles (profiles that you created prior to installing the SCS plug-in), issue the following command:
zowe scs update
Profiles are updated with secured credentials.
