# Master Password

When using Particle Network on Wagon, security is paramount. You’ll encounter two types of passwords to help protect your wallet and assets:

## 1. **Master Password**

* **Purpose:** Used to encrypt and back up your local MPC (Multi-Party Computation) key shard.
* **Important:** This password is **only known to you**. Wagon or Particle **cannot recover** it if lost.
* **Recommendation:** Store your Master Password securely and avoid losing it — it's essential for account recovery.

## 2. **Payment Password**

* **Purpose:** Acts as an extra verification step before signing transactions.
* **Flexible:** Unlike the Master Password, this can be turned off or reset anytime via your profile settings.

These passwords ensure your account remains safe and fully under your control — even when using convenient social login options like Google or Apple.

For more technical details on password configuration and behavior, refer to the Particle Network docs.
