# verifyPassword

> Verifies that a password is correct for the wallet's encrypted backup

## Function Signature

```typescript theme={"system"}
verifyPassword(params: {
  accountAddress: string;
  walletMetadata: WalletMetadata;
  password?: string;
}): Promise<void>
```

## Description

Verifies that the supplied `password` correctly decrypts the wallet's backup. Throws if the password is wrong or the cached metadata is stale.

## Parameters

### Required Parameters

* **`accountAddress`** (`string`) - The wallet address. Must match `walletMetadata.accountAddress`.
* **`walletMetadata`** ([`WalletMetadata`](/node/reference/types/wallet-metadata)) - The cached metadata for this wallet. Must include `externalServerKeySharesBackupInfo`.

### Optional Parameters

* **`password`** (`string`) - The password to verify.

## Returns

* **`Promise<void>`** - Resolves if the password is correct (or no password was needed).

## Example

```typescript theme={"system"}
import { authenticatedSvmClient } from './client';

const svmClient = await authenticatedSvmClient();
const walletMetadata = JSON.parse(await redis.get(`wallet:${accountAddress}`));

await svmClient.verifyPassword({
  accountAddress,
  walletMetadata,
  password: 'user-password',
});
```
