ok thanks alot. i seen that coinbase recommends the yubico ones. i think its about $45 on amazon. i only have a grand in my trading account. should i get it you think? would i need it for both laptop and phone? i dont see how it would plug into phone since connections are different.
In that case I believe that in order to work in a phone you would have to get the NFC version -

Regarding your investment I really recommend you never disclose how much you hold - for your own safety. And regarding your question I always recommend 2FA whenever it's available - it's another layer of security that makes your account be more secure and I think that is never a downside.
