On Dec. 23, 2009, Hillary Clinton, who was then secretary of state, sent an email on her private server to her aide Huma Abedin asking how to switch her home phone to fax mode. In the long chain that followed, Ms. Abedin explained, more than once: “Just pick up phone and hang it up. And leave it hung up.”

Madame Clinton, c’est moi.

The former first lady and current presidential candidate is also like a lot of other men and women who were adults when personal computers came into use, and who to this day cannot scan, iChat, use Spotify or hook up their Roku, and would prefer not to let the world — or their younger colleagues — in on their tech inadequacy. It’s the kind of admission of age-based incompetence best shared with only the closest advisers.

Hillary has Huma. I have extension 2020.

That’s the number reporters here at The New York Times call when they are having trouble with the paper’s secure server; technicians are available 24/7 to help people who can’t remember their password, don’t understand iCloud or don’t know how to get past the locked-key icon that blocks intruders from getting in.

I know them by name, and they sigh when they hear mine.

Unlike Bernie Sanders, the Trump campaign is not sick and tired of hearing about Mrs. Clinton’s emails. Yet oddly, in all the failings hurled at Mrs. Clinton at the Republican National Convention during the past week — venality, murder and reckless disregard for national security — there was no mention of her internet ignorance.
