Passkey Wallets

A passwordless, non-custodial wallet secured by your device’s biometrics.

Passkeys are a modern, secure, and user-friendly way to create and access your Aura wallet. They eliminate the complexity of traditional crypto wallets while maintaining full self-custody of your funds.

What are passkeys?

Passkeys are a passwordless authentication standard (FIDO2/WebAuthn) supported by all major devices and browsers. Instead of remembering a seed phrase or password, your device’s built-in security (Face ID, Touch ID, Windows Hello, fingerprint, or PIN) acts as your key.

When you create a passkey wallet on Aura:

• A cryptographic keypair is generated securely on your device
• The private key is stored in your device’s secure enclave (it never leaves your device)
• The public key is used to derive your Alephium wallet address
• Only you can authorize transactions using your biometrics or device PIN

How passkeys work

1. Create your wallet

   Choose a username and authenticate with your device (Face ID, fingerprint, etc.).

2. Your keys, your control

   A unique cryptographic keypair is generated and stored in your device’s secure hardware.

3. Sign transactions

   Every trade, deposit, or withdrawal requires your biometric confirmation.

4. Cross-device access

   Passkeys can sync across your devices via iCloud Keychain, Google Password Manager, or Windows Hello.

Are passkeys non-custodial?

Yes, absolutely. Passkeys are fully non-custodial:

• Your private key is stored only on your device’s secure enclave
• Aura never has access to your private keys
• Only you can authorize transactions with your biometrics
• You maintain complete control over your funds at all times

This is the same level of security as traditional self-custody wallets, but without the risk of losing a seed phrase.

Security benefits

Property	Why it matters
No seed phrase risk	Nothing to write down, lose, or have stolen
Phishing resistant	Passkeys are bound to a specific website domain, making phishing attacks ineffective
Hardware-level security	Keys are protected by your device’s secure enclave (TPM, Secure Enclave)
Biometric protection	Every transaction requires your face, fingerprint, or PIN
No browser extensions	Reduces attack surface compared to browser-based wallets

Creating your passkey wallet

1. Open Aura

   Visit testnet.aurabets.io and click Connect.

2. Choose passkey

   Select Create Passkey Wallet.

3. Pick a username

   Enter a username (this is just for your reference).

4. Authenticate

   Approve with Face ID, Touch ID, or Windows Hello.

5. Done

   Your wallet is created and you’re ready to deposit funds.

Recovering your wallet

Since passkeys sync across your devices:

• Apple devices — synced via iCloud Keychain
• Android — synced via Google Password Manager
• Windows — synced via Microsoft account

To access your wallet on a new device, simply click Sign In and authenticate. Your passkey will be available if you’re signed into the same account.

If you lose access to all devices and your cloud account, you will lose access to your wallet. Consider adding your passkey to multiple devices as a backup.
