I have a personal org where I used to try my trailhead challenges. Few days back I was getting email from Salesforce org about job I had been running on my personal email id. I opted for not receiving these emails so I went into salesforce > setup > email > email deliverability and I set email to - no email instead of system email only. And Now I have forgotten password to my org and I cannot receive password reset email from Salesforce.
What Can I do? I cannot go inside the org anymore.
