# init(user:password:persistence:)

Creates a URL credential instance initialized with a given user name and password, using a given persistence setting.

```
init(user: String, password: String, persistence: URLCredential.Persistence)
```

## Parameters

`user`

The user for the credential.

`password`

The password for `user`.

`persistence`

A [`URLCredential.Persistence`](/documentation/Foundation/URLCredential/Persistence-swift.enum) value indicating whether the credential should be stored permanently, for the duration of the current session, or not at all.

## Return Value

An instance of [`URLCredential`](/documentation/Foundation/URLCredential), initialized with user name `user`, password `password`, and using persistence setting `persistence`.

## Discussion

If `persistence` is [`URLCredential.Persistence.permanent`](/documentation/Foundation/URLCredential/Persistence-swift.enum/permanent), the credential is stored in the keychain. If `persistence` is [`URLCredential.Persistence.synchronizable`](/documentation/Foundation/URLCredential/Persistence-swift.enum/synchronizable), it is also stored to the user’s other devices.

## See Also
