3. What can I do with Ledger Flex?

With Ledger Flex, you get the best of all worlds—cutting-edge security, a sleek touchscreen, , and everyday convenience.

Manage your digital assets

You can securely view, transact, and manage over 15000 cryptos. Moreover, with the Ledger Live app, you can do much more with your device. Stake supported assets to earn rewards, swap and bridge crypto using integrated services, set a DCA strategy into your favorite tokens, and enjoy the benefits of multi-chain web3 with confidence.

Clear-sign on your Ledger device

Moreover, Ledger’s Clear Signing initiative makes transactions human-readable and verifiable directly on the secure touchscreen. Would you send someone a blank check to sign in real life? Taking this analogy to crypto, you’re actually risking your transactions if you’re trusting third-party screens or dApps to show you real information about your transaction.

Make no mistake, blind signing has led to loss of funds more times than you think. So now, with Ledger’s wider secure touchscreens, you don’t have to trust a third-party screen to show you information about the transactions you’re about to sign—you can actually verify the data at a glance and also sign the transaction directly on your Ledger Flex’s secure touchscreen.

Suppose you want to lend some Staked ETH on AAVE, you would need to make it clear that the intent is to execute this particular function. There also needs to be a link between what you intend to do and what will actually be executed on-chain. 

However, smart contracts don’t make it easy to help regular people understand what is going on because transaction details are presented to you (often on insecure screens) in an encrypted manner. Moreover, your hardware device must also be capable of relaying this information to you in a readable manner. This is why transacting on the Ledger Flex, with its wider secure screen, comes in. It makes understanding crypto easier, along with Ledger’s Clear Signing to give you confidence, visibility, and comfort when executing transactions.

Customizable lock screen

You can also make the Ledger Flex represent your digital identity in the real world—it allows you to manage and display NFTs directly on the device’s screen. But this functionality isn’t just limited to NFTs, you can also display any other image on the lock screen, adding an even more personal touch.

Ledger security key

You can also use the Ledger Security Key app for two-factor authentication and passwordless logins across supported platforms. Your Ledger Flex doesn’t limit its security to just crypto, it becomes your passkey across various apps and websites too!

4. What if I lose my Ledger Flex?

If you lose your Ledger Flex, your assets remain secure as long as your 24-word recovery phrase is safe. You can restore access to your funds on a new Ledger device using this recovery phrase. It’s crucial to store the recovery phrase in a secure and private location, as anyone with access to it can control your assets.

As an added layer of protection, you’ll be prompted to set a 4- to 8-digit PIN code when you first set up your Ledger Flex. This PIN acts as the first line of defense. If someone tries to access your device, it will automatically reset after three incorrect PIN attempts, making unauthorized access virtually impossible.

Alternatively, Ledger Recover helps you regain access to your crypto assets if you lose your Ledger Flex device or your 24-word recovery phrase. This optional, subscription-based service creates a secure backup of your Secret Recovery Phrase. It works by securely backing up your recovery phrase, encrypting and splitting it into three fragments, which are stored with independent custodians. Even Ledger can’t access it.

In case of loss, you can restore your private keys by verifying your identity via the Ledger Live app and setting up a new Ledger device. This optional service is especially helpful for users who want additional protection and reassurance around recovery phrase management.

5. Does Ledger Flex have any disadvantages?

Ledger Stax features Qi wireless charging, allowing you to power up your device effortlessly by placing it on any compatible charging pad—adding a layer of convenience to its premium design.

Unlike Ledger Stax, Ledger Flex does not support wireless charging. However, it’s equipped with a built-in rechargeable battery designed for extended use and easy USB-C charging.

6. How many apps can Ledger Flex hold?

Ledger Flex can support multiple apps, but has a slightly lower memory space compared to the Ledger Stax. Its 1.5 MB memory space is plenty of room to download apps that support crypto accounts across chains. 

In practice, users typically install a mix of larger apps (e.g., Bitcoin, Ethereum) and smaller dependent apps. The Ledger Live app shows you the exact distribution of your storage to plan accordingly.

For the Ledger Nano S (320 KB total), only up to 3–10 apps fit with a range of large to small-sized apps. Similarly, for the Flex, with a mix of larger apps (~100 KB) and optimized apps (~20–30 KB), it could reach a total of between 10-17 apps. The storage space for the amount of apps will vary depending on your usage.

Given that Ledger devices allow users to install and uninstall apps as needed via Ledger Live, the maximum capacity is a theoretical limit and practical usage often involves using fewer apps at once.

7. How do I set up Ledger Flex?

To set up your Ledger Flex:

1. Turn on the device by pressing the power button.
2. Download and install the Ledger Live app on your smartphone or computer.
3. Follow the on-screen instructions in Ledger Live to pair your device via Bluetooth or USB-C.
4. Set a PIN code on the device.
5. This is the most important step – write down and securely store your 24-word recovery phrase.
6. Complete the setup by installing the apps you need to manage specific cryptocurrencies.
