2FA Authentication code has kept my email account safe several times in the past when I was still using a weak password, I always get a notification that someone is trying to access my Gmail account, they failed to get in because they need 2FA code access but thats not why I'm here, I'm just curious if there is any crypto wallet that has 2FA security? I've never seen one.
What 2FA you use with your gmail? Do you receive a mobile sms or you use secondary codes generated from your account settings?
If you want to receive an sms, you won't ever find this feature in a non custodial wallet because this required a third part confirmation and non custodial clients are not designed to be so.
If you are using login codes which you save securely elsewhere, then it's the same by keeping safe your seed phrase ; you will always use a strong password to access your non custodial wallet but the havker would need the seed phrase even he can get the password unless the device is hijacked.
Btw, if you are always receiving emails that someone is trying to login into one of your accounts, better to change it in all the accounts related with.
