Auto Login with Cloudflare

I am testing this plugin, I think Jetpack's secure login feature can be replaced with this plugin, this means I can remove Jetpack after my testing is done.

Good job, thank you so much.

Great Auth plugin

Clean, simple, and precisely what it promises.

I just configured my complete setup using Cloudflare Access with auth via AzureAD and auto-login to wp-admin. This plugin is gold!

Combined with the Authenticated Origin Pulls feature of CF, this is seamlessly intertwined enterprise-level security for free.

I love this! Thank you!

Super simple way to allow a single sign on to your Wordpress site when using Cloudflare Access.
