Thank you. Changing wallet is a bit hassle for me. I already input all my seed phrase on different devices and on my physical seed phrase back up. Is there a way to imposed a security feature on Electrum that works like authenticator? I'm thinking a scenario that my laptop might get hacked so I want to prevent hacker to brute force my wallet through the use of authenticator something like that.
Since you've used your current wallet as a hot wallet, there's really no way to make more secure than it is right now. The only thing you can do is create a more secure wallet, and keep it more secure in perpetuity. If you have regular payments to an old wallet that you don't want to change, you can monitor it until the balance is more than you care to risk, and move it to a more secure wallet. Still more hassle, but the added security is worth it.
Take note that there's a third-party service fee for using Electrum's 2fa wallet.
It'll be automatically added as an extra output to your first transaction, then in every "
N" number of transactions. (
varies depending on your selection).

The fees for Electrum's 2FA provider aren't horrible, but in my opinion the money would be better spent on a hardware wallet. Also, the same thing can be done for free with a 2 of 2 multi-sig wallet. With each wallet on a separate device, such as one on a computer, another on a phone, you get the same level of security, and added privacy. A hardware wallet would still be more secure, however.
