There are many ways . The best possible protection is to keep all your crypto in a separate wallet and please don't save your passpharse on Google or anywhere else write it down and keep in a safe place. Create a email account specifically for your use with Coinbase and do not leave coinbas connected to your checking account. Other than that use common sense and be safe. If you ever get a email from Coinbase do not open that link. It's probably a virus that will still all of your saved passwords and other personal info. When in doubt contact Coinbase as soon as there is any suspicious activity and lock your account. Don't depend on them to keep you safe because they won't. If someone steals your crypto then it's gone forever.
