OneKey Mini Crypto Hardware Wallet and KeyTag Review

Today, we will be taking a look at the OneKey Mini Crypto Hardware Wallet and KeyTag Titanium Backup plate. When OneKey contacted me, and asked if I was interested in trying out their crypto storage products, I was intrigued. So said yes.

I have to admit, I’ve only heard about this company recently, but they have been around since 2019 and is well rated by Trust Pilot with 4.1/5 stars.

The first product we’ll look at is the OneKey Mini. This is a compact, mini-size hardware cold wallet. While the second product is the OneKey KeyTag, which is basically a solid metal plate made from Titanium that you can store your key and secret phrases. It’s resistant to corrosion and heat, with temperatures up to 1,688 °C.

The recovery phrase is the master key to your cryptocurrency funds. Never share it with anyone else.

If you lose access to your mobile or devices, you will be able to restore your wallet with your recovery phrases.

However, if you lose your recovery phrases, you will not be able to restore your wallet and you will LOSE all your cryptocurrency funds.

I’ve used other crypto wallets in the past, such as the CoolWallet Pro which I’m still using. I’ve also tried hardware wallets from Ledger and Trezor, both are very good products and I fully recommend them. It will be interesting to see if the OneKey Mini Crypto Hardware Wallet will be any good.

I’ll be transfering some of my cryptos to the OneKey Mini. I will be checking its functionality, the ease of use, and security. Before we start, here’s a little blurb taken from OneKey’s website …

OneKey hardware wallets and applications are 100% open source. You can either use the OneKey App alone or with a OneKey hardware wallet, which will complete the other. They are both friendly for beginners. Open source means that OneKey’s codes, with nothing hidden, are open to inspection by everyone.


  • We use both a secure chip (SE) and a universal chip for our hardware wallets. Again, everything from 3D source files to PCB circuit boards and, most importantly, firmware source code can be found in our code repository.
  • If a wallet doesn’t open source its code, you’re likely to worry that it’s hiding a backdoor that could compromise the security of your assets. Our code is fully publicly hosted on Github, so anyone can inspect or use our code
  • Wallet helpers and seeds created through OneKey are encrypted and stored locally so that only you can decrypt the information and our servers do not and cannot store any of the user’s private data. There are no more centralized institutions involved and you are in full control of your crypto assets.
  • Privacy is a top priority OneKey’s servers do not store any private data about users and do not covet their personal information.
  • No Bluetooth Requires USB Type-C connection for use.

The OneKey Mini

Package includes the OneKey Mini device, instruction manual, OneKey stickers, USB-C cable and 2 recovery sheets (BE CAREFUL with your private keys and recovery phrases)


A Closer Look

OneKey Mini is a compact mini-size crypto hardware wallet featuring a 1.44-inch screen. It measures 71 x 34 x 6.8mm and weighs in at just 15.6g. It’s powered by a USB-C connection, but unfortunately there’s no wireless or Bluetooth connectivity.

On the right side of the device, youi’ll find a “Lock” button, and on the front there’s 4 cursor buttons, up, down, left and right. These buttons allow you control and select the menu options on the display.


Setup and Configuration

The OneKey Mini was pretty easy to setup and configure. Just plug the included USB-C cable to power up the device and follow the on-screen instructions.

As soon as you power up the device, the first thing you need to do is to create a wallet. Next, use the included recovery sheet to write down the backup recovery phrase in the right order. You are given a choice of 12, 18 or 24 recovery phrase words.

Next, it will ask you to set your PIN number. Please be careful and REMEMBER your PIN. If you forget your PIN, you will NOT be able to access the OneKey Mini. However, you can change your PIN on the device after it resets (after 10 failed PIN attempts, the device will initiate a factory reset, and then you can reset your PIN, but do not forget the recovery phrase.

Once your recover phrases and PIN are verified. The OneKey Mini is ready to use. There are two ways of connecting the OneKey Mini …


Using desktop computer (Windows or MacOS)

Go to OneKey’s website and download the desktop application Install the app, and follow the instructions.

When you make any kind of transaction (buy, sell, send, swap etc), you will be prompted to verify your account with your PIN on the device.


Using Mobile App (iOS or Android)

Update: According to OneKey, it is not recommended to import your key phrases that was generated from the OneKey Mini in to the app. Only do it when the device is lost or broken, and you need to transport your cryptos to a safe place as an emergency or last resort.

Because the OneKey Mini does not have Bluethooth connectivity, the only way to connect to the mobile app is to import the key phrases manually.

Download and install the app n your mobiel phone and follow the instructions on how to manually import your key phrases.

The mobile offer the same options as the desktop application including, crypto markets, NFTs, Explore, and settings.

When you make any kind of transaction (buy, sell, send, swap etc) on the mobile app, you will be prompted to verify your account with your password (which you created during the setup).


The OneKey KeyTag Titanium Backup Plate

Next we have the OneKey KeyTag. It is not a hardware wallet for storing your cryptos, but a solid metal plate made from Titanium for storing your key and secret phrases as a backup. Insode the box, you’ll find a  user guide, 2 keytags, and an automatic center punch.


A Closer Look

The OneKey KeyTag is made of aerospace-grade TC4 titanium alloy, and it’s resistant to corrosion, water and heat, with temperatures up to 1,688 °C. It’s about 1/4 the size of a credit card and weighs in at only 14g, which means you take it everywhere with you.

All the wallet recovery phrases are generated from the BIP39 Wordlist. This alphabetical list contains 2048 words. You can store up to 24 recovery phrases on this backup plate.

Remember the secret key phrases that were generated for you when you first created the hardware wallet? Well, you can not store them on on this backup plate, rather than on a piece of paper.

Use the user’s guide to match the phrases from your hardware wallet, and then use the automatic center punch tool to punch in the corresponding dots on to the backup plate.

Instead of letters and words, KeyTag smartly help users to record the number of each recovery phrase. Each KeyTag has one extra row for passphrases.

Verdict and Conclusion

Overall, the OneKey Mini is a decent crypto hardware wallet, although I’ve seen better ones on the market. Mind you, this is their entry-level hardware wallet so it will lack some features found on their higher-end models, such as color touchscreen and wireless connectivity.

If you’re planning to use the OneKey Mini, we recommended you download and install the desktop application for the best experience, that’s because it only offers USB connectivtiy.

The only thing I wished it had, was Bluetooth connectivity. Without Bluetooth, you can not connect it with OneKey’s app wirelessly. However, you can manually import the OneKey Mini wallet in to app, using the recovery keys/phrases.

As for the KeyTag Titanium Backup Plate … Well, it’s one of the most intriguing product I’ve come across. Its robust constuction and indestructible features, makes if one of the safest and most secure backup you can use. Just try and not to lose it!

If you’re looking for an affordable and secure hardware wallet to store your cryptos, then the OneKey Mini is a decent product that will do just that. It’s compact, light-weight and easy to use, and you can get it for only USD $59.

If you have to import your key phrases to use the app, does that not defeat the purpose uf using a cold storage solution?
