In some cases you may want to always prompt for credentials, without using the Connect with Options commands. Similar to the Ad Hoc syntax (putting a ? as credential name), you can do this by configuring the Credentials settings like this:
A configuration as shown above (a ? character as credential name) will always display the Credential Picker dialog to either select one of the existing credentials or enter a username and password.
The credential picker can easily be controlled by keyboard and allows find-as-you-type as well as search (using CTRL+F) to quickly find the credential you need. Also note, that a reconnect of the connection (as long as it is not closed) will always use the specified credentials from the picker - not configured in the connection properties.
