Just make sure not to add any 2FA that is connected with SMS and phone numbers, this is literally worst thing related with 2FA.
Now
I think the 2FA will be those of authentication apps like Aegis because it is the most secure and I like something about this forum, they know what not to go form.
Now that being said, people should be aware of risks when using 2FA, that means if you lose backup codes you will lose your account, and not even theymos with all his mighty powers will be able to restore it.
If an address is staked or has been used someehere before on this forum, signing a message with the address willnstill be enough proof and the account can be recovered. It would be done in a way that it would be recoverednasnitnisnfone elsewhere.
