Username masks
This feature allows you to define the information format that the participants must use when registering for the event, limiting the type and number of characters allowed as a valid answer to specific fields.
By creating username masks, the answer type plain text will be replaced by special characters defined by you, and the event will allow attendees to register using their social security numbers, registration numbers, among other options as their username.
How do I enable usernames?
To enable this tool, at the company level, go to Account > Tools on the left sidebar menu. When accessing the tools, look for the Login section. Then, you should enable Usernames by checking the checkbox. By doing that, the participants can be registered in the event by the admin and access the Virtual Lobby and mobile app with no need to type their email addresses.

How can I create username masks?
With the Usernames feature enabled, you can register your attendees without their email being their username to access the event.
You can choose different types of structures to use as a username, such as: passport number, ID number, social security number, enrollment number, among others. To do so, follow the steps listed below:
- Go to Settings > Headings

- Click in + Add heading on the left upper corner. A new window will appear.

- Choose the option Form - Username in the placeholder type field.
Below, in the Type heading value, you can add the new text that will appear to your attendees. For example, in case you have chosen to have Passport numbers as the username, the Type heading value can be: Passport number.
- As you can see in the image above, when choosing the option Form - Username, a third field will appear: Field Mask.
Under this field, you can add the mask value you wish to appear when your attendees register. Masking an answer box is changing the type and number of characters allowed as a valid answer to this question.
For example: when creating a question that requires the participant's passport number, you may want to limit these responses to 9-digit numeric characters.
When filling out the field mask, keep in mind that:
- The # character represents any number, allowing participants to enter only numbers in the question's answer. For example, ### would allow the user to enter only three numbers.
- The letter A represents any letter, allowing participants to type only letters in the answer to the question. For example, 'AAAAAAAA' would allow the user to enter only seven letters.
- The N character represents any "number or letter", allowing participants to type only numbers or letters in the question's answer.
- If you wish to use an official structure (with dashes, period) you can add it to the field, and this structure will appear on the registration form. Click here for further information on special characters.

How does the username mask affect forms?
On the registration form and custom forms, at the field username, the attendee must enter information based on the mask previously defined.
For example, if a username mask was created with 9-digit numeric characters, attendees will only be able to type nine numbers on the Passport number field for their username. Notice, on the image below, that the field name has already changed on the form.
On the image below, on the left, you can see the default text Username. On the right, you can see the username mask that was created by the event organizer.

How does the username mask affect lists?
- On custom lists, in the username field, you must enter information based on the defined mask.
For example, if a username mask was created with 9-digit numeric characters, you will only be able to type nine numbers on the Passport number field for their username.
On the image below, on the left, you can see the default text Username. On the right, you can see the username mask that was created by the event organizer.

- On the attendees list, in the username field, you must enter the information based on the mask previously defined.
On the image below, on the left, you can see the default text Username. On the right, you can see the username mask that was created by the event organizer.

How does the username mask affect the app login?
Even if you have created a mask, the username field on the app will still allow the user to type any information they want, but in case they do not type exactly what is registered in the attendees' list, they won’t be able to login to the app, as their access information is not correct.
In other words, the username information registered under People > Attendees must be identical to the one used to access the app.

Special characters
On the registration form and on the platform, if the event organizer has added "-" or ".", these characters will be automatically displayed, as shown below:

But the same doesn't happen on the app, the characters "-" or "." will not be automatically displayed on the username field on the app. Therefore, when accessing the app, the user must manually add the special characters, since they are not automatically filled.
