Note that your LikeCoin account is tied up with your digital wallet address.
If you signed up on a desktop/laptop computer, the wallet information is most probably stored under your MetaMask plugin. You have to open the Chrome browser, login MetaMask, and then visit like.co. You can then access your LikeCoin account.
If you signed up on mobile, your wallet information is stored under your trust wallet. Similarly, you have to open the trust wallet app, choose the "browser" tab and visit like.co to access your LikeCoin account.
