Per T308656, we want to collect data on certain high priority preferences so that we can understand the usage of this page on desktop and mobile. Currently, to the best of our knowledge, the only data available to us is of the allowlisted preferences defined for PrefUpdate.
We would like to track (anonymised) data points for how many users are making changes to:
* Their password (Special:ChangeCredentials)
* Their email address (Special:ChangeEmail)
* The checkboxes in the Notifications tab (The "Notify me about these events" section on en.wiki)
Because we don't want to store any identifying information for password and email changes (the only data points we need are that a change occurred, the date of that change, and a signifier for whether the change happened on mobile web or desktop), simply adding these options to the PrefUpdate allowlist may not be the path forward.
**Questions**
* How can we track changes to these three preferences while collecting the least amount of information possible about the user making the change?
