# 2. Access

1DEX employs advanced access authentication mechanisms to ensure asset security while providing a seamless login experience:

## Passwordless Experience

* **OAuth Authentication:** Supports quick login via third-party accounts like Google and Apple, lowering the barrier to entry for users.
* **PassKey Authentication:** Using PassKey technology, users can authenticate their identity via biometrics (e.g., fingerprint or facial recognition) without traditional passwords. PassKey combines cryptography and device binding to prevent phishing attacks and ensure private key security.
* **Application Scenarios:** For key operations like depositing funds, placing/canceling trade orders, and withdrawing assets, users must verify their identity via PassKey to complete on-chain signature transactions, ensuring the security of each step.\ <br>

## Various Assets Support

Supports a wide range of mainstream blockchain assets (e.g., BTC, ETH, USDT), with smart contracts enabling transparent on-chain asset management and verification.
