Disable login to an application without deleting it

[dan]

Is there a way to disable logging into an application without disabling/deleting it?

Per https://github.com/FusionAuth/fusionauth-issues/issues/1810 I'm not clear what my options are.

You have a couple of options.

• If you use the hosted login pages/authorization code grant, disabling all grants in the application settings page will prevent people from logging in.
• If you use the login API and have customer-based API keys, you could turn on the 'require API key for login API' and then disable the customer's API key.
• If you have the Enterprise plan, you could set up an IP ACL for a unroutable IP range.

However, the easiest way to make sure an application cannot be logged into is to deactivate the application.
