1. Check if you are still unregistered or if you did register your EOS Account
First step is to go to this site, scroll down a little bit and then enter your Ethereum address (public key) and click Submit.
If you did not register, you could choose an EOS Account Name and create a new keypair for your EOS Account.
Follow this "older" video tutorial on how to do this.
How to register your ERC-20 EOS tokens (unregistered tokens) on the EOS mainnet and get your EOS tokens on the EOS blockchain
With Metamask:
With an alternative method (hardware wallet like Ledger/Trezor):
Note: The alternative method is more complicated. If you have a problem with the alternative method, you can follow the guide here on connecting your hardware wallet to Metamask to use the simple method with Metamask.
2. If your Account is not on the unregistered list, your EOS Account exists already, and you can use the Fallback or the Lostkey method
Fallback - In this case, use eoskey app with your Ethereum private key (it works offline), and it’ll give you your EOS private key. Then download the Anchor Wallet, set up an Anchor Account, then import your EOS private key to get access to your EOS Account. If the Fallback does not work, try as well the Lostkey Method.
Registered: In this case, use the EOS private key for registration. We recommend the EOS Anchor Wallet. After, download the Anchor Wallet, set up an Anchor Account, then import your EOS private key to access your EOS account.
Lostkey: If you forgot your EOS private key and never touched your EOS Account, you can create a new key here: https://eosauthority.com/lostkey. Attention: The lostkey method can be used only one time. Make sure you save your EOS private key this time, or you will lose access to your EOS Account. If you perform the lostkey method with another wallet other than Metamask, follow the how-to here.
The lost key recovery https://eosauthority.com/lostkey has been reactivated by the Block Producers on the July 12, 2021, and extended until June 30th 2026.
