I am concerned I will lose my all Salesforce Certifications.
Actually, I have a Developer org with my personal email for which I had configured Salesforce Authenticator based two-way authentication. Last week I lost my old phone. Now, I'm not able to login into that personal developer org which is Connected to WebAssessor account and to trailhead account.
I have sent a couple of emails to "firstname.lastname@example.org" but didn't get any reply.
As 23 Aug is the due date for various certifications maintenance, If I won't be able to login into there then I'll lose my Salesforce credentials which need to be maintained by 23 Aug.
Any single suggestion to get this problem resolved will be highly appreciated.
