Once you have taken all the steps to verifiy your email address, you can delete your Facebook account without losing access to your TicketSwap account.
Can I login at my old TicketSwap account with the alternative login method?
No, unfortunately that’s not possible. If you chose to remove your Facebook profile, your account on TicketSwap will be removed correspondingly. This means you cannot access your old account anymore if you removed your Facebook account without verifying your email address first.
