# set(_:for:)

Adds a credential to the credential storage for the specified protection space.

## Declaration

```swift
func set(_ credential: URLCredential, for space: URLProtectionSpace)
```

## Parameters

- `credential`: The credential to add. If a credential with the same user name already exists in space, then credential replaces the existing object.
- `space`: The protection space to which to add the credential.

## Discussion

Discussion If the credential is not yet in the set for the protection space, it will be added to it. If you override this method, also override set(_:for:task:).
