## Why are two passwords needed?

When you create a Locker account, you will notice the system requires both an account password and a **Master Password**. This design separates **identity authentication** from **data encryption**.

### 1. Account Password (Login Password)

This password is used to verify your identity when you log in to the system.

* **Advantage:** Can be recovered at any time.
* **Limitation:** Does not use encryption technology to protect the data inside your Vault.

### 2. Master Password

This is your most important password — the only key that encrypts and decrypts your data.

* **Security:** No one (including Locker) can access your data without this key.
* **Important:** You must **NEVER** forget or share it with anyone, as doing so could result in permanent data loss.

## Simpler alternatives

Locker provides solutions so you do not need to enter multiple passwords while still keeping your data secure.

### Replacing the Login Password

* **Social accounts:** Sign up or log in with Google, Facebook, Apple, or GitHub.
* **Passkeys:** Log in quickly using biometrics (face, fingerprint) or your device **PIN**.

### Replacing the Master Password

Although the Master Password is required, you can set up faster unlock methods:

* **On Mobile:** Go to `Menu` > `Settings` > `Unlock with Face ID/Touch ID`.
* **On Web/Desktop:** Use a physical security key or Passkeys to decrypt your Vault.

<Note>
  Regardless of which alternative method you use, always remember or store your **Master Password** in a safe place, as it is your last line of defense.
