What’s Wrong With The Tangem Crypto Cold Wallet? 

https://www.youtube.com/watch?v=a4XGy16hNDo
Transcript:
 There’s no shortage of videos on YouTube extolling the virtues of the Tangim Crypto  Wallet.  And for good reason.  It’s inexpensive, durable, portable, secure, wireless, and backed by a 25-year warranty.  What’s not to like, right?  I’m going to answer that exact question in this video.  The Tangim Wallet is a great wallet for sure, but it does have some drawbacks.
 I’ll be discussing those in this video so you have all the information you need to make  a decision as to whether the Tangim wallet is right for you.  Like I said, the Tangim crypto wallet is a fantastic wallet.  In fact, I have Tangim version 1 and Tangim version 2 right here.  I also have a discount code in the description below so that you can save 10% off the retail price if you decide to buy one of these  really interesting wallets.
 Oh, and while you’re checking it out, don’t forget to  hit the subscribe button. Okay, the basic idea for the Tangium wallet is that your  seed phrase is stored here on the card and you use the mobile-based application  to perform all of your transactions. Those transactions that require  authorization are signed by holding this card to the back of your phone.
 Tangent wallet cards use  NFC technology to communicate with most modern cell phones, and the seed phrase never leaves  the secure element chip hidden inside this card. It’s easy to set up, use, and store. It’s a great  wallet for the beginners  as the learning curve is very low.
 The big difference between Tangent version 1 and Tangent  version 2 is that while the first version only allowed for automatic seed phrase creation  and storage, the second version allowed the user to import their own seed phrase or let  the secure element chip create one and store it on the card for them.  Still, Tangent recommends users let the software and chip create a seed phrase for them during the  account setup process.
 They believe that seed phrase mismanagement is the number one reason  why people lose their crypto. And they’d be right. So if Tangent Wallet is so great,  what are the downsides? Let’s get to those. The first downside to if Tangent Wallet is so great, what are the downsides? Let’s get to those.  The first downside to the Tangent Wallet is it doesn’t allow for passphrases.
 A crypto passphrase  acts like a 13th or 25th word added to your seed phrase and adds an additional layer of security  to your crypto account. In my opinion, this is the biggest drawback to the Tangent Wallet and  the main reason I don’t keep much crypto stored on this wallet.
 While I opinion, this is the biggest drawback to the Tangem wallet and the main reason  I don’t keep much crypto stored on this wallet. While I was researching this video, however,  Tangem did announce that this is a function they are actively working on. So that’s great news.  Another feature they recently announced that they were working on is multiple addresses in the  account.
 Accepted privacy practice is for a Bitcoin wallet to generate a new Bitcoin  address every time you want to receive Bitcoin into the account. The Tangent wallet at the moment  does not allow for multiple addresses in the wallet. That means if you give someone your  address to send you crypto, they are privy to every transaction you’ve ever made in that account,  including the balance you hold on that account forever.
 That’s not good privacy practice.  And the third drawback to the Tangent Wallet  is no multi-sig capabilities.  While I don’t really think this is a big deal  for most individual users,  some power users think it’s absolutely critical  and therefore would avoid the Tangent Wallet altogether.  The fourth drawback to the Tangent Wallet altogether.
 The fourth drawback to  the Tangent Wallet is a big one. The security chip inside this card cannot be updated. The firmware  cannot be changed ever. The firmware it ships with is the firmware that will be on the chip  forever and ever. The crypto space is in a constant state of flux, and developers should have the ability to make changes to the base layer or firmware of the chip inside a hardware wallet to keep up to date with the latest changes in crypto technology.
 Tangent might point to the significant number of updates that they’ve made to the mobile application, and they should be congratulated for all the work that they’ve put into that app.  But it’s not a substitute for the flexibility of firmware updates to the chip on the card. My guess is that their  excuse would be that firmware updates to the security chip represent a security vulnerability.
 I’m not sure. And the fifth drawback to the Tangent wallet is seed phrase options. The company recently announced  that they’re going to give users the ability to generate a 24 or 12 word seed phrase during  account setup. But just like Lucy pulling the football away from Charlie Brown right before  he kicks it, Tangent also added that unfortunately the 24 word seed would have the same entropy,  that means randomness, as the 12 word seed, thereby nullifying  any increase in security that the longer seed phrase would provide. Again, another limitation
 to using a security chip that can’t be updated. And the next drawback to the Tangent Wallet is  that they use a mobile-only proprietary application. As I mentioned, the application  that interacts with these Tangent cards is mobile only, and the cards only work with that particular application.
 If you lose  access to that application, your crypto is gone forever, or at least stuck on the blockchain.  And the seventh drawback to the Tangent wallet is the hidden seed phrase option. In my opinion,  the default recommendation by Tangium to create a hidden  seed phrase and store it on the secure chip of this card without ever showing the user that seed  phrase is not a feature, but a bug.
 During the account creation process, the seed phrase is never  revealed to the user. Instead, it is kept private and securely stored on the chip in the card.  Instead, it is kept private and securely stored on the chip in the card.  Sounds great, but what if you lose the card?  No biggie, because the cards ship in a 2 or 3-pack.  I happen to have a 3-pack right here of the second version of the Tangent wallet.
 But if you happen to lose all of these cards, again, your crypto is lost forever.  There is no way to recover the seed phrase from the card,  and there is no way to get your crypto off the application without the card. They work together,  and neither one can work without the other.
 So it kind of doubles your vulnerability, right?  If you lose access to the application, crypto gone. If you lose access to the cards, crypto gone.  The solution, of course, is to use your own seed phrase during the account setup,  which you could restore to a third-party wallet in case you lose access to the application or the physical cards. If you need help creating your own seed phrase, check out this video for an explanation.
 Alright, the next drawback to the Tangent Wallet is a deal-breaker for most crypto purists.  And that is that the card doesn’t have a screen.  It’s just a piece of plastic. It doesn’t have a battery. It doesn’t have a screen or anything. Even this piece of  crap, the SecuX Shield Bio has an e-ink screen so that you can verify transactions before signing  them. Most other crypto wallets have a built-in screen so that you can verify transactions before you sign them.
 A double check, if you will.  If your mobile device gets compromised, it would be easy for an attacker to insert a crypto address into your Tangent app and hijack your crypto and have it sent to their address rather than the intended address that you were trying to send some to.  In other words, the application would show one address,  but in fact, the crypto was being sent to another address.
 And you can’t verify that address or even the amount you’re sending  on a card with no screen.  Do I think that’s likely?  No, but it is possible.  And without a screen, you’re just hoping that the app you’re using is safe and clean.  It’s not the best security protocol.  And the final drawback to the Tangent Wallet is that the new Tangent Wallet  has the ability to reset the access code using a backup card.
 In other words, if a thief got a hold of two of these cards,  it’s really easy for them to reset the access code  that acts like a password for your wallet account.  They even go as far as to put the  instructions to do so on Reddit. For some people, this may be a feature, but it dramatically reduces  the security of the whole system.
 This is why Tangent recommends storing these cards separate  from each other geographically, which for some of us is not possible, including me.  All right, I’m going to finish this list with a story. About a month ago,  I needed to reset the Face ID on my phone because I was having trouble recognizing  this super handsome face.
 After I did that, I lost access to many apps on my phone, including  Tangent. The other apps were easy enough to restore the Face ID login functionality, but the Tangent app would not let me in. So I thought, no biggie, I’ll just  erase the app, reinstall, and then restore the account using my card. No problem. Well, after  multiple, multiple attempts to restore the account with my Tangent card, I finally sent Tangent an  email and the title was Lost Crypto because without getting into the application, I can’t get  to my crypto. They still haven’t responded. I think it’s been about four or five weeks now.
 That is not impressive. I was able to restore the account to a third-party wallet because when I set  up the account, I used my own seed phrase instead of the one generated by the card.  And eventually I got the app to respond and restore the account using my backup card.  Crisis avoided. With no help from Tangent, of course.
 I couldn’t help but think during this entire process that if I had let the Tangent app create a seed phrase for me and store it on the card,  I never would have been able to restore it  to another third-party application and potentially would have lost the crypto forever. That is not  acceptable. Listen, there is no perfect wallet and no perfect crypto storage solution.
 In reality,  every storage solution offers a different combination of security, convenience, and privacy. For me, the Tangent wallet leans heavily towards convenience  at the expense of security and privacy. For smaller sums of crypto, I think it might be a  fantastic solution. But for me, for life savings of crypto, I really wouldn’t recommend it.
 And  I’d probably stick with more traditional cold storage wallets, like the Trezor or the OneKey Classic.  And I happen to have a video review of the OneKey Classic. I’ll put the link for it in the description below.  So let me know what you think of the Tangent Cold Storage Wallet and how it fits into your storage system in the comments below.
