In this article I explain quickly how you can change the administrator email address without having to worry about confirmation emails, databases and all sorts of other hassle.
Questions you may have in advance
No, you don’t need to access the database directly.
Nope.
Definitely not.

Here’s how to change the email address
Login to your WordPress admin dashboard and visit your “General Settings” page. In the url of your site you see something like this:

Now let’s modify that URL a bit and change options-general.php to options.php so it looks like this:

This changes the “General Settings” page into the otherwise hidden “All Settings” page. On this page you are able to change the admin email address without going through the confirmation process.

Just search for admin_email option, change your email address, scroll to the end and press the “Save Changes” button. All done! You now changed the admin email address without going through any complicated procedures.
Disclaimer
Although the process of changing the admin email address is fairly easy to go through, use it with caution. The “All Settings” page allows you to change a lot more than just the admin email, so be very careful. Things can break. Also, the security measure of sending out a confirmation email in the regular process is there for a reason. So only use this method if the current email address is no longer accessible.
The reason I wrote this article is because several posts on the internet describe methods where you need to access the database or install yet another plugin. I believe accessing the database method is even more dangerous than the method I mention and installing a plugin is overkill.
