Attributes are fields that let you get information from the user's profile.
Some of these attributes aren’t enabled by default. Here’s how to turn them on or make them editable for your users.
Turn on an attribute or make it editable
To do that you can head over to this link. https://app.signitic.com/settings/attributes. It lets you see the attribute list, disable them, make them visible, or editable.

The inactive labels show which fields aren’t enabled. The "Visible" labels mean the fields are on but can’t be edited. The "Editable" labels mean the field is visible and users can edit it.

To edit this status, you can just click on "Edit" and pick the value you want.
There are several important fields—it's up to you to see which ones you find most interesting.
Feel free to contact support in the chat that's available in the app.
