A client notified us that with Wave.webaim.org Web accessibilitity test Forgot.password.php page is being 'marked' as having uncorrect Heading build 

I was able to add a H1 by changing a the language string for "to reset your password". 

But the H3 I had to change the moodle core file element-header.mustach (lib/form/templates) 

It would be great if the /login/forgot_password.php has a correct Heading build up with a 

• H1 for "Change password" (or something similar) 
• H2 for the Search by username and Search by Emailadress

So we can comply by WCAG rules.
