# \<PassGenerator />

If you specify contracts, the user will be presented with a list of all NFTs within the specified contract addresses. After selecting an NFT, the user will need to sign a message to validate ownership, which then allows the creation of a pass representing ownership of that NFT.

```
import { PassGenerator } from '@ethpass/sdk';
import { ethers } from 'ethers';
const provider = ethers.getDefaultProvider()

const NFTPassGenerator = () => {
  return (
    <PassGenerator
      provider={provider}
      contracts={[
        {
          address: '0x8765e43765fA715Af70A1e4483814660B48b497C',
        },
      ]}
    />
  );
};

export default NFTPassGenerator;

```

By specifying an array of policyIds, the user will see a button to generate a pass, but only if their connected wallet meets the criteria set within the policy.

```
import { PassGenerator } from '@ethpass/sdk';
import { ethers } from 'ethers';
const provider = ethers.getDefaultProvider()

const PolicyPassGenerator = () => {
  return (
      <PassGenerator
        provider={provider}
        policyIds={['07d79222-4dc8-4a1d-bb1e-0ce5608f2125']}
        showRequirements
      />
  );
};

export default PolicyPassGenerator;

```
