For the new wallet, would it be wise to add 2fa to the new electrum wallet?
To know more about 2fa enabled on Electrum, read this:
TrustedCoinThere are fee charges while making transactions which you can see in the link above, if you are okay with it, 2fa is another layer of protection. Make sure you backup your 2fa, I will recommend open source ones like Agies and andOTP. Backup your seed phrase, know that your seed phrase is not stored on your Electrum wallet if it is 2fa wallet.
