I was trying to set up a local (development) site for my personal blog. Since I enabled Jetpack’s SSO, the local site redirected to SSO page and took me to my live blog’s Dashboard page. So, I was looking for a way to disable Jetpack’s SSO.
Here is how to disable Jetpack SSO and login to your local/staging Admin dashboard.
Step 01: Disable the Jetpack plugin
You can rename the Jetpack plugin folder and this will disable the plugin without logging into the Admin dashboard.
Step 02: Access the login page
Once you disable Jetpack plugin, you can access the /wp-login.php (login page) of your local site.
