Authereum is a cryptocurrency wallet like MetaMask. Unlike MetaMask it does not require a browser addon, so works on any device like your phone or tablet. You can use your Authereum account to deposit money to Erasure Bay.
Authereum is a non-custodial wallet which means no one but you has access to your money. Authereum makes it easy for non-technical users to keep their currency secure while providing advanced features. Read here for a more advanced understanding of Authereum’s contract-account architecture.
Erasure Bay does not currently support MetaMask.
