HTTPS
Why use HTTPS ?
If you sign in to WordPress.com via a non-secure Internet connection, like a public Wi-Fi connection at your local coffee shop, your account may be more vulnerable to hijacking. To keep the bad guys out, we recommend selecting the “Always use HTTPS when visiting administration pages“ option from your profile page which will SSL-encrypt your connection while in the WordPress.com dashboard. Save the change by clicking Update Profile. When you log back in, you’ll be rolling with SSL encryption.
doneDoes it slow down WordPress.com ?
With this option turned on, you may find that WordPress.com is more sluggish over the https connection. That’s because nothing that’s transmitted over SSL can be cached, so it takes some extra work to re-download all the information on a page.
To speed things up, click the Turbo button in the upper right corner of your dashboard. This will direct you to install Gears, which will dramatically improve the performance of WordPress.com in https mode.
How do I get those annoying security warnings to go away?
If you’re using Internet Explorer, you may receive warnings as you navigate around your admin with HTTPS enabled. To disable those, follow this process:
1) Go to Tools > Internet Options in your browser menu.
2) Add *.wordpress.com to your list of trusted sites under the Security tab. Make sure to uncheck the box for “Require server verification (https:) for all sites in this zone.
3) Set Internet Options> Security> Trusted Sites> Custom Level> Miscellaneous> Display Mixed Content to “Enable” (you’ll have to do lots of scrolling to get there).
3) Click OK on all windows.
