Currently, Talend does not have a built-in feature allowing the integration of password vaults.
Password vaults is a security requirement for some large companies.
The following documentation provides three possible workarounds:
Managing database access with HashiCorp Vault in a Job
Build an Enterprise Level Password Vault with Talend and CyberArk
You can create a custom routine using the How to set password encryption in Talend Studio documentation available in the Talend Help Center.
