+## Description
+
+To ensure secure storage of your login credentials when using the CLI, Infisical saves them to a password manager if one is detected. 
+If a password manager is not available, your credentials are stored in an encrypted text file. 
+
+
+<Accordion title="Supported password managers" defaultOpen="true">
+  By default, the most appropriate password manager is chosen to store your login credentials. 
+  For example, if you are on macOS, KeyChain will be automatically selected.
