The first thing to do is check that you submitted your email on the required page. The password reset process requires you to enter your email address twice - once to confirm that you have an account in the system, and then again to actually request the password reset email. Double check that you have entered your email address into both pages.
If you have entered your email address on both pages and still haven’t received an email the next step is to check your spam or junk folder. If the email isn’t there, then send an email to email@example.com and we can send you the reset link by a different method.
