# \&hash

General Option! ([`&push`](/advanced-settings/setup-parameters/push.md), [`&room`](/advanced-settings/setup-parameters/room.md), [`&view`](/advanced-settings/mixer-scene-parameters/view.md), [`&scene`](/advanced-settings/mixer-scene-parameters/scene.md))

## Aliases

* `&crc`
* `&check`

## Options

Example: `&hash=99e5`

| Value    | Description     |
| -------- | --------------- |
| (string) | Hashed password |

## Details

You can add `&hash=STRING` this to a guest's URL instead of [`&password`](/advanced-settings/setup-parameters/and-password.md) if you want to check the password. That means the password turns into another string.

If you added a password to your room, the guests' invitations in the director room get 'hashed' automatically:\
![](/files/Z5hipAQcrZh912ka2aIs)

If you want to hash your password manually, you can use this link:\
<https://vdo.ninja/examples/changepass.html>\
Just enter your room password and you get the hash value.

For example:\
<https://vdo.ninja/?room=roomname&password=password>\
->\
<https://vdo.ninja/?room=roomname&hash=99e5>
