How is Tangem Mobile Wallet secured on my phone?

When you create a Tangem Mobile Wallet, it is generated directly on your smartphone. The app generates cryptographic entropy and encrypts all sensitive wallet data using the phone’s built-in secure hardware — Secure Enclave on iOS or StrongBox on Android.

The encrypted data is stored in the system-provided secure storage: Keychain on iOS or Keystore on Android. This data is isolated from other apps and protected by the operating system.

Why is Tangem Hardware Wallet more secure than a Mobile Wallet?

The Mobile Wallet provides a high level of security using your phone’s secure hardware and encryption. It has passed an independent security audit by Cure53, a well-known German cybersecurity firm. Cure53 has audited products for Mozilla, Coinbase, NordVPN, Mullvad, MetaMask, and many other security-focused applications.

However, the Mobile Wallet relies on a general-purpose, internet-connected device. For the highest possible security, Tangem Hardware Wallet is recommended, as it keeps private keys fully offline.

Can Tangem itself access my funds on a Mobile Wallet?

No. Tangem has zero knowledge of your private keys. 

The keys are generated locally and stored in your smartphone's secure environment. Tangem cannot access, recover, or freeze your assets. True self-custody means you, and only you, control your crypto.

Does a Mobile Wallet use a seed phrase?

Yes. Tangem Mobile Wallet uses a recovery phrase (seed phrase) as its backup and recovery mechanism. 

A Mobile Wallet cannot be created without a recovery phrase.

How can I view the seed phrase for a Mobile Wallet?

You can view your recovery phrase in the app settings:

1. Open the Tangem app.
2. Tap the three dots in the upper-right corner.
3. Select the wallet.
4. Tap Backup.
5. Tap Recovery phrase.
6. Confirm with biometrics or access code.

Make sure to store it securely and never share it with anyone.

Where is the access code stored in a Mobile Wallet?

The access code is stored locally on your device. It is used to protect access to the Tangem app and authorize sensitive actions. It is never shared with Tangem or stored externally.
