Yes! You can log in into your old account but you should have any social account with the same email id which you have used earlier.
So for example, if you have used superstar@rajinikanth.com you should have a social account under the same email id
Facebook superstar@rajinikanth.com
Twitter superstar@rajinikanth.com
Amazon superstar@rajinikanth.com
Provided these accounts all have an identical validated email address. hence you could access your old account.
We key logins by email address, so generally speaking, logging in with the same email address, even using a different login method, will “just work”.
