Lumia 640 won't sign in after hard reset

I had to hard reset a Lumia 640 but I cannot sign back in. Looks like the Reset Protection was on. The error reads "Hey! Looks like your phone was reset and you didn't turn off Reset Protection. You need to enter your Microsoft account Information to continue using this phone."

I removed the phone from the account already but got no recovery Key. Is there any other way to get the recovery key.

I am using the same account to sign back in but nothing happens.

Any ideas?
