When an user register using facebook and want to delete the account they don’t have a password created so they have to logout and click the reset link, create a password, log-in and delete the account.
That’s a lot for an average user and someone can get really confused ending in more support request
Add a reset password link to “delete account” modal
write “delete” to confirm the account termination and not the password
or maybe they’re more solution to this that i don’t know
