+ 
When we are working with a private repository, we can modify the list of peers
+ 
we allow by using the `rad id` command with its `--allow` and `--disallow`
+ 
options. Both options can be specified multiple times in the same command line call:
+
+ 
Here we will add Bob and Eve's DIDs to the `allow`list:
+
+ 
```
+ 
$ rad id update --title "Allow Bob & Eve" --description "" --allow did:key:z6Mkt67GdsW7715MEfRuP4pSZxJRJh6kj6Y48WRqVv4N1tRk --allow did:key:z6Mkux1aUQD2voWWukVb5nNUR7thrHveQG4pDQua8nVhib7Z -q
+ 
...
+ 
$ rad inspect --identity
+ 
{
+ 
  "payload": {
+ 
    "xyz.radicle.project": {
+ 
      "defaultBranch": "master",
+ 
      "description": "radicle heartwood protocol & stack",
+ 
      "name": "heartwood"
+ 
    }
+ 
  },
+ 
  "delegates": [
+ 
    "did:key:z6MknSLrJoTcukLrE435hVNQT4JUhbvWLX4kUzqkEStBU8Vi"
+ 
  ],
+ 
  "threshold": 1,
+ 
  "visibility": {
+ 
    "type": "private",
+ 
    "allow": [
+ 
      "did:key:z6Mkt67GdsW7715MEfRuP4pSZxJRJh6kj6Y48WRqVv4N1tRk",
+ 
      "did:key:z6Mkux1aUQD2voWWukVb5nNUR7thrHveQG4pDQua8nVhib7Z"
+ 
    ]
+ 
  }
+ 
}
+ 
```
+
+ 
To remove a peer's DID, we can use the `--disallow` option. Let's remove both of them again:
+
+ 
```
+ 
$ rad id update --title "Remove allow list" --description "" --disallow did:key:z6Mkt67GdsW7715MEfRuP4pSZxJRJh6kj6Y48WRqVv4N1tRk --disallow did:key:z6Mkux1aUQD2voWWukVb5nNUR7thrHveQG4pDQua8nVhib7Z
+ 
...
+ 
$ rad inspect --identity
+ 
{
+ 
  "payload": {
+ 
    "xyz.radicle.project": {
+ 
      "defaultBranch": "master",
+ 
      "description": "radicle heartwood protocol & stack",
+ 
      "name": "heartwood"
+ 
    }
+ 
  },
+ 
  "delegates": [
+ 
    "did:key:z6MknSLrJoTcukLrE435hVNQT4JUhbvWLX4kUzqkEStBU8Vi"
+ 
  ],
+ 
  "threshold": 1,
+ 
  "visibility": {
+ 
    "type": "private"
+ 
  }
+ 
}
+ 
```
+
+ 
Note that using both `--disallow` and `--allow` with the same DID will result in
+ 
an error:
+
+ 
``` (fails)
+ 
$ rad id update --title "Remove allow list" --description "" --allow did:key:z6Mkt67GdsW7715MEfRuP4pSZxJRJh6kj6Y48WRqVv4N1tRk --disallow did:key:z6Mkt67GdsW7715MEfRuP4pSZxJRJh6kj6Y48WRqVv4N1tRk
+ 
✗ Error: `--allow` and `--disallow` must not overlap: ["did:key:z6Mkt67GdsW7715MEfRuP4pSZxJRJh6kj6Y48WRqVv4N1tRk"]
+ 
```
+
+ 
Allowing or disallowing the same peer twice will result in an error the second
+ 
call, since there is no update specified:
+
+ 
```
+ 
$ rad id update --title "Allow Bob" --description "" --allow did:key:z6Mkt67GdsW7715MEfRuP4pSZxJRJh6kj6Y48WRqVv4N1tRk -q
+ 
...
+ 
```
+ 
``` (fails)
+ 
$ rad id update --title "Allow Bob" --description "" --allow did:key:z6Mkt67GdsW7715MEfRuP4pSZxJRJh6kj6Y48WRqVv4N1tRk -q
+ 
✗ Error: no update specified
+ 
✗ Hint: an update to the identity must be specified, run `rad id update -h` to see the available options
+ 
```
+
+ 
If we attempt to change the list while also changing the repository to `public`,
+ 
then the command will fail since there is no longer an allow list to work with:
+
+ 
``` (fails)
+ 
$ rad id update --visibility public --allow did:key:z6Mkt67GdsW7715MEfRuP4pSZxJRJh6kj6Y48WRqVv4N1tRk
+ 
✗ Error: `--allow` and `--disallow` cannot be used with `--visibility public`
+ 
```
+
+ 
Let's change the repository to `public`:
+
+ 
```
+ 
$ rad id update --title "IPO" --description "" --visibility public -q
+ 
...
+ 
```
+
+ 
Now, if we attempt to change the `allow` list we also get an error with a
+ 
helpful hint:
+
+ 
``` (fails)
+ 
$ rad id update --allow did:key:z6Mkt67GdsW7715MEfRuP4pSZxJRJh6kj6Y48WRqVv4N1tRk
+ 
✗ Error: `--allow` and `--disallow` should only be used for private repositories
+ 
✗ Hint: use `--visibility private` to make the repository private, or perhaps you meant to use `--delegate`/`--rescind`
+ 
```
