I registered a Google account very long ago (maybe 10+ years), and I just remember it today.
I tried to log on it but got this:
The account name is a domain name, like firstname.lastname@example.org and I still have access to this domain. But I guess there's no luck for Google to take look for my case.
I am very sure the password is correct because when I input another one, it would not redirect me to this page.
Are there any tips? Really hope to get back this account.
BTW, I can even access the email sending to this inbox via another Gmail because I set up an auto-forwarding filter in this Gmail. Just tried it a few seconds ago.
