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.

I don't recommend using a wallet with 2FA.
If you want to have 2FA, you have to use a custodial wallet and give a third party full control over your fund.

The only wallet allowing you to have 2FA and have full control over your fund at the same time is electrum which only supports bitcoin.
The 2FA wallet in electrum is actually a 2 of 3 multi-signature wallet in which transactions are signed by the user and trustedcoin (a third party)
Electrum gives you a seed phrase allowing you to disable 2FA at any time.

Note that for making transaction with electrum 2fa wallet, you have to pay additional fee to trustedcoin, so they sign your transactions. (Click here (https://trustedcoin.com/#/faq#fees) to see how much trustedcoin charge.)
The network fee will be also higher due to using multi-signature addresses. (The network fee will be still higher even if you disable 2FA using your seed phrase)

Warning:
Download electrum only from its official website (https://electrum.org/#home) and do not forget to verify your download (https://bitcointalk.org/index.php?topic=5240594.0).


Again, I don't recommend using a wallet with 2FA.
Bitcoin has been created to give you full control over your fund. With 2FA, you lose your full control.

Custodial wallets are always not the best of options but, they've got there advantages too which spans from, recovery passwords through some  verification process. A 2FA is an added security should you prefer this custodial wallet to non custodial but, the risk in using a custodial wallet is more compared to non custodial. Aside from the non recovery of details in the case of non custodial wallet, I think it's the more preferable as, your totally in charge of everything. Remember, not your keys, not your coins.

On the contrary, if your looking for a custodial wallet with a 2FA authentication enabled, you could try out Coinbase Wallet but, I'll st maintain that, its not for the bests although, its a multicoin wallet but custodial never the less. Non Custodial wallets like Electrum and Mycelium would serve you more.

2FA is recommended when you are making use of custodial wallet or custodial exchange as an additional protection of your account and  funds, before an hacker would be able to compromise your account after login details have been compromised, the attacker will need the OTP that your 2FA app or hardware is generating. Some users do not have option than to use custodial service especially when using custodial exchanges, especially, traders fall into this category of people because they trade often, converting from one coin to another to make profit (although trading is highly risky, which deserves to be noted).

But as hosseinimr93 pointed out, I do not see any reason you should use a custodial wallet when there are noncustododial available options, most 2FA wallets are custodial wallets, you do not have the private key of your wallet, the company that provide the custodial wallet has the private, and you are given only address generated by the private key, the reason the company have control over your account, they can decide to freeze your account or make some situation inconvenient for you. Unlike noncustododial wallet, you have your private key, you have full control over your coins. Also hackers like to target custodial service as it hold large amount of coins.

But Electrum wallet is a noncustododial wallet which is exceptional and have the 2FA setup but in a way you will have 2 keys while TrsutedCoin has one key. Two keys are required to make transaction, one from you and one from TrustedCoin, the 2FA OTP is required to make TrsutedCoin to provide key for transaction you want to broadcast. For me not to repeat much, hosseinimr93 has provided you necessary information. But try and read about the fee that would be changed by TrustedCoin which could be too high for your liking, but 2FA gives your Electrum wallet more security. There are other options you can even go for like using a multisig wallet, wallet on airgapped device or using buying an hardware wallet.

Not only this, with 2FA, you will have to pay more fee for your transactions because additional fee will have to pay for remote server. Electrum's 2FA (https://electrum.readthedocs.io/en/latest/2fa.html) guide.

In addition, normal or 2FA wallet, you are able to restore/ recover your wallet with seed you have. In the end, 2FA only secure that specific digital wallet file on one device, if you lose it (by a broken device, by whatever reasons), if you have seed, you can restore your wallet. It means that if you lose your seed, you lose your Bitcoin.

Zelcore allows using 2FA on its wallet, it's just that this wallet is complicated to use for a newbie but pretty secured, I use this wallet to store my Flux coins.

Almost all custodial web wallets where you have to create an account have the 2FA feature. But technically, 2FA here is used to protect your account not your wallet. Besides, it's not recommended to use custodial and /or web wallets (Not your keys, not you coins).
The closest thing to 2fa you can have with a non-custodial wallet is a 2-of-2 or 2-of-3 multisignature wallet and you need to keep each signing key on a different device

If a wallet is not open source and also complicated like the wallet you mention then it is a big no for me especially when the site uses Cloudflare.

If the 2FA protected the account automatically it also protects the custodial wallet.

2FA is good but its old and there are some ways to Bypass the 2FA codes now and we are talking about the cryptocurrency wallet which comes with private keys which is more secure and almost impossible to brute force so all you need to do is to keep your private keys safe and you also can try airgapped wallet which means your wallet is never connect to internet and you are going to broadcast the transaction from another device.

2FA is very important because sometimes I show my login password gotten anyone and he login in website, specifically when I save my password in Google chrome it’s Somehow password Lick so 2FA is best way to saved account.

Do you mean the same Zelcore^[1] wallet that runs on Solana blockchain? You are making things complicated for your self except if you want to use a multi bridge to switch between chains which is off point to what Op is searching for.
The best OP can use is to use a 2-3 multisignature wallet as advised above, you can still spend from your wallet with the right seed phrase and disable the option when you reinstall the wallet(Electrum) if anything happens in the future but I didn't see anything like that on Zelcore, not safe my friend.

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.

It is worth mentioning that a 2FA setup with a 2of2 multi-sig scheme is not a good option because of the risk it has. You are basically sharing the custody of your own money with a third party that if they refuse to sign transactions (eg. they could demand KYC first!) you will not be able to spend your money any more.

Wasn't khaled talking about non-custodial non-2fa wallet with multi-sig support? (based from "the closest thing")
In which case, instead of using a 2fa authenticator app, the second cosigner will be on that device instead.

Zelcore and security don't go hand in hand. The private key is not generated randomly. You create a username and a password, and the private key is based on that entropy. There is a good explanation of how it works in the posts in this thread > https://bitcointalk.org/index.php?topic=5035274.0.

You shouldn't give your passwords to anyone or log in using unknown devices. You should also not save your passwords in Chrome and other browsers because password-stealing malware know how to access these locations and got hold of the data. 

Honestly, I would like this idea of 2FA security but since this belongs to another company thats not even decentralized it automatically mean it's not safe for keeping assets or using with crypto wallets, maybe in future we will see something more secured and fully decentralized that we can use to add more security to our crypto wallets.

Hmm maybe; but all the 2FA wallets that exist and are considered non-custodial are using a third party. For example Electrum uses 2of3 and the third party is TrustedCoin or GreenWallet uses 2of2 and Blockstream is the third party.

Additionally if the user owns all the keys keeping them on separate devices, it is no longer called 2FA, it is just a multisignature wallet.

2FA is the best way to secure your accounts and websites login information but not for crypto wallet, you need to learn more about centralized wallets and none centralized wallet, if you see any crypto wallet that allows 2FA just know that your keys aren't completely yours.

2FA is very good one to apply on the exchange wallet platform to make password more secured, if the person is using weak password, 2FA can prevent from the account not been hack, which i have benefited from it in several time email notification trying to login account.

You can make use of multi-signature wallet (which requires more signatures to successfully process a transaction ).
Import second (or more) seed(s) to another device(s). Or hardware wallet(s) can be used as 2fa device(s) as well.

A crypto wallet that supports 2FA and gives you private keys is hard to come by, for example, Electrum is one of them but only supports BTC, just be careful on your hunt because any crypto wallet that supports 2FA and gives users no access to their seed or private keys are not safe, so don't confuse the two thinking they are the same thing, 2FA doesn't mean your wallet is safe.
