Disable the admin email verification

add_filter( 'admin_email_check_interval', '__return_false' );

How it works

Since version 5.3, WordPress asks administrators every six months to confirm that the site’s admin email is still correct. On sites you manage for clients, it’s a screen that confuses people. The admin_email_check_interval filter sets how often it appears. Returning false turns it off.

Before you use it

WordPress sends security, update and password reset notices to that address. Check it’s right in Settings → General before you turn the reminder off.

How to check it works

You won’t see the screen again after login. There is nothing else to check, it simply stops appearing.

How to undo it

Remove the line. The check comes back on its usual six-month cycle.

How to add this snippet

3. Save, then open the site and check that everything works. If something breaks, remove the code.
