As described in this KB, Application Credentials give by default SFTP only access to a single application in your account. If you want to additionally enable SSH access with the same credentials, follow these simple steps.
Step 1: Login to Cloudways Console
Click here and log in with your credentials.
Step 2: Select Application
Tap on “Applications” on the top menu bar and then select your target application from the list (the one you want to enable SSH access for).
Step 3: Enable SSH access
Go to “Application Settings” in Application Management section and then enable “SSH Access” under the General tab.
That’s it! Now all the Application Credentials defined for this application will have SSH access to it, on top of the default SFTP access.
