I recently wanted to delete one of my account on a website. And it turned out that it was associated to my gmail account (which I don’t use anymore). Is there a way to find all the website accounts that are associated with this mail address? (So I can delete my google account after that).
p.s.: I’ve already tried this solution but it’s surely not everything that I’ve had connected with my account
You could try waiting for a new change in laws concerning privacy, such as the GDPR and wait for the flood of incoming emails about companies which changed their privacy policy.
