Passcodes are what attendees use to access your Pigeonhole on the Audience Web App (https://www.pigeonhole.at). It is therefore important to choose a suitable passcode.
When deciding on an event passcode, you can either randomly generate one, or enter one of your own. An event passcode can only consist of letters and numbers, and have a length of 4 to 20 characters. Spaces, underscores or hyphens are not supported. Event passcodes are also case-insensitive. If an active Pigeonhole has used a passcode, it cannot be used again in another Pigeonhole until that Pigeonhole has ended. A Pigeonhole will have ended once the complete Pigeonhole duration plus a two days buffer has elapsed.
If you want your Event Passcode to be memorable and related to the event name, you can either use the event name or an abbreviated form of your event name. It can also be helpful to append a number series or the year to the event passcode. Alternatively, if you wish for some security, you can choose a random or cryptic passcode.
Reusing Event Passcodes
You can reuse passcodes in your Pigeonholes with a caveat - Pigeonholes must have ended before the passcode can be reused. This means there also isn't a way to reserve passcodes in advance and passcodes are allocated on a first-come-first-served basis. To clarify, a Pigeonhole is determined to have ended only after the complete Pigeonhole duration (i.e. 7 days), plus another two days buffer has elapsed.
