Without an account, 2key cannot incorporate your sharing activity in the campaign smart contract, and therefore cannot reward you for your activity.

If you just copy-paste a 2key SmartLink without using the “Refer and Earn” option, your sharing activity will go to that SmartLink account holder.

No worry though, opening an account only takes a few seconds and you can sign it with your Facebook, Civic, or Google account, or with your email.
