How guest sign-in data is validated

Learn how validation rules help prevent fake email addresses, names and postcodes from being submitted during the guest Wi-Fi sign-in process.

Written by Stephanie Desveaux

Validation rules block the most obvious fake or invalid guest sign-in entries. They cannot prevent all fake data, but they significantly reduce the most common occurrences.

📌 Note: You cannot completely prevent fake data from being entered. Only a verification email with a clickable link could achieve this, but guests may not have internet access while signing in to Wi-Fi.


Validation rules

The following validation rules apply during the guest login process.

Email addresses

We apply the following checks to email addresses entered during sign-in:

  • We reject emails that appear on our list of clearly fake addresses. This list currently contains around 200 commonly used fake entries - such as [email protected], and is updated over time based on reports from our own systems.

  • We reject any email containing invalid characters.

  • We reject any email where the same character appears four or more times consecutively, for example, [email protected].

Names

We apply the following checks to names entered during sign-in:

  • We reject names containing invalid characters - such as numbers or dollar signs.

  • We reject names where the same character appears four or more times consecutively, for example, aaaaa.

  • We reject names entered as 'test', 'testing', 'unknown' or 'none'.

  • We reject names fewer than two characters long.

Postcodes

We reject postcodes entered as 'test', 'testing', 'unknown' or 'none'.


What guests see

If a guest enters any invalid information, an error message appears beneath the field on the login form, asking them to enter valid information.
